4iiii’s Viiiiva ANT+ to Bluetooth Good Bridge & Center Fee Strap In-Intensity Evaluate

Somewhat beneath a yr in the past 4iiii’s introduced the primary tool available on the market to bridge the distance between ANT+ equipment and Bluetooth Good enabled telephones.  In doing so, they doubtlessly spread out the door to saving customers from having to re-purchase pricey equipment merely to make use of them with apps on their telephones.  However the query is: Is that this tool the saving grace people had been searching for?

I’ve been the usage of the tool for months now, checking out each and every conceivable mixture.  As a result of I wish to be clear about my evaluations, as soon as my analysis duration with the Viiiiva has elapsed, I ship it again to 4iiii’s in Calgary.  Easy as that.  Sorta like climbing in wasteland trails – depart simplest footprints.  In the event you in finding my evaluate helpful, you’ll use any of the Amazon or Suave Coaching hyperlinks from this web page to lend a hand make stronger long run evaluations.

Finally, on the finish of the day be mindful I’m similar to some other common triathlete in the market.  I write those evaluations as a result of I’m inherently a curious individual with a generation background (my day task), and thus I try to be as entire as I will.  However, if I’ve neglected one thing or should you spot one thing that doesn’t moderately jive – simply let me know and I’ll be at liberty to get all of it taken care of out.  Additionally, since the generation international continuously adjustments, I try to return and replace those evaluations as new options and capability are added – or if insects are fastened.


Let’s get this child unboxed.  Don’t fear, this received’t take lengthy.  First, is the field:


At the again is a diagram that explains the way it all works and a fragment of the apps it really works with.  However I’ll speak about what the other compatibility ranges are later.


Pulling out the center of the field, we discover a plastic shell with the center price strap and transmitter pod, at the side of a quickstart information.


Right here’s the 2 pieces within the field putting out in combination like BFF’s:


Like maximum middle price straps, it’ll are available in two items: The strap and the transmitter pod.  The transmitter pod pops into the little steel snaps and holds the entire thing in combination.  It’s adjustable after all, so you’ll regulate the strap as you notice have compatibility.


At the again you’ll realize each the ANT+ and Bluetooth Good emblems.  The battery sits in that little door you notice underneath.  When you’ve reached  200 hours (or when it makes a decision to prevent pairing in your tool), you’ll wish to change out the battery.  Because it simply makes use of a CR2032 user-replaceable battery, it’ll simplest take a couple of seconds and about $2-3US.


Subsequent up is that quick-start handbook.  It’s beautiful elementary, however that’s nice. By way of time you end right here in this publish, you’ll be neatly versed in methods to use it.  Or, you’ll be asleep. Or each.



With that, let’s get into why this strap is so distinctive.

Background and figuring out what the product does:


Adequate, so that you get that the strap is by hook or by crook other, however what’s it in reality doing?  Smartly, let’s beginning off with the core situation: ANT+ to Bluetooth Good.  The explanation that is attention-grabbing to parents is that during the upward push of telephone apps, ANT+ equipment had been reasonably restricted for app integration.  That is due (basically) to the loss of ANT+ chipset make stronger inside the Apple gadgets (that means, no ANT+ within the iPhone).  To get ANT+ at the iPhone, you’d in a different way want an adapter putting out the ground of your telephone.  At the Android platform we see a handful of gadgets that natively make stronger ANT+.  However maximum Android gadgets that need ANT+ connectivity wish to accomplish that by way of OTG adapters (extra issues putting off your telephone).

With the expansion of telephone apps and the loss of any local ANT+ solution to get into the Apple platform, you begin to see the upward push of Bluetooth Good within the health house.  Bluetooth Good is determined by Bluetooth 4.0, which began being offered into telephones about 18 months in the past.  Bluetooth Good adoption has been in large part catapulted ahead by way of Apple, while on Android it lags considerably in each and every side.

Inside the well being house, the primary Bluetooth Good tool profile we noticed used to be for the Center Fee strap, ahead of even the primary Apple tool used to be out that supported Bluetooth Good.  A ‘tool profile’ is basically some way for a given tool variety to keep in touch in an ordinary type.  ANT+ has them, and Bluetooth Good has them, although after all whilst identical they don’t communicate to one another (other protocols).  Standard examples of tool profiles come with the center price strap, bicycling pace/cadence sensor, bicycle energy meter, operating footpod, and so on… All of them have quite other technical names (i.e. ‘stride sensor’ as an alternative of operating footpod), however in the long run they’re beautiful identical between the 2 wi-fi protocols.

Taking a look at marketplace position up till this level, ANT+ middle price straps had been ubiquitous with gadgets like Garmin, Timex, CycleOps and plenty of others.  On the similar time, so have plenty of biking equipment like the rate/cadence sensor and the ability meter.  The problem is that whilst there are many Bluetooth Good middle price straps – they received’t paintings together with your present Garmin tool (or in reality virtually the rest rather then a telephone).  At the biking accent facet, there are just one or two corporations making Bluetooth Good pace/cadence sensors (such because the Wahoo Blue SC), and so they too received’t paintings together with your present ANT+ motorcycle computer systems.  And after all, at the energy meter facet, there’s just a unmarried corporate that lately produces an on-bike Bluetooth Good energy meter – the Levels Energy Meter (which is twin ANT+/Bluetooth Good).  That signifies that everybody else with pricey $1,000-$2,000 ANT+ energy meters is not able to make use of them with telephone apps natively.


For the reason that, you’ll obviously see the marketplace for an affordable tool so that you can convert ANT+ into Bluetooth Good, permitting people to make use of their present ANT+ equipment with each ANT+ and Bluetooth Good computer systems/presentations.  No one needs to re-purchase a $1,500 energy meter merely to attach it to a telephone app.  And the similar is going for inexpensive equipment as neatly.

Thus, Viiiiva.  Viiiiva acts as that conduit between one international and some other, enabling one to take ANT+ information resources and convert them in real-time to Bluetooth Good – all whilst nonetheless appearing as a typical middle price strap.

How the Viiiiva is other than a typical middle price strap:


So whilst Viiiiva would possibly glance similar to some other middle price strap, the Viiiiva is in reality the combo of 3 other core purposes – which might in most cases be 3 other merchandise.  Most often, that is the way you’d divide it up:

1) ANT+ Center Fee Strap: Maximum Garmin customers are aware of the ANT+ strap, and the Viiiiva may be an ANT+ strap that may even broadcast ANT+ in your Garmin unit (all the time).

2) Bluetooth Good Center Fee Strap: For the ones customers with newer telephones, the Viiiiva similtaneously announces your middle price over Bluetooth Good to supporting apps.

3) ANT+ to Bluetooth Good Bridge: It’s this ultimate piece that’s in reality the place the magic filling is.  Inside of that little pod it receives ANT+ tool transmissions and rebroadcasts them as Bluetooth Good gadgets.  Call to mind it like a stay translator going from one language to some other.  With this capacity we will be able to now bridge the distance between ANT+ gadgets equivalent to energy meters, and get in touch with apps on platforms just like the iPhone with out local ANT+ make stronger.

To position this in a extra easy analogy, it’s necessarily like a ANT+ strap and a Bluetooth Good strap were given in combination one night time, did the romance dance, and had a child.  And even if the fogeys didn’t discuss every others languages, that child ended up being bilingual.  Kind of.

Now, let’s speak about what the Viiiiva isn’t:

1) It’s now not an analog middle price strap: Which means, that it received’t paintings with gymnasium apparatus or treadmills.  However given you’re studying this publish, I believe you’ve most probably were given your personal tool you’d use anyway.

2) It doesn’t paintings with legacy Bluetooth same old: That signifies that you must have a telephone that accommodates Bluetooth 4.0 in it should you’re connecting to an app.  These days that’s principally the rest after the iPhone 4s, plus third technology iPad and past.  As of this writing, there are nonetheless no Android or Home windows Telephone apps that make stronger Bluetooth Good for software utilization round well being profiles.  Regardless that each telephone platform corporations have introduced plans to take action, it’s nonetheless many ways off.

3) It doesn’t paintings with Polar gadgets: Polar has their very own proprietary W.I.N.D. protocol to be used at the majority in their fashionable gadgets, and this received’t paintings with that (nor the gadgets that use the analog or virtual non-WIND straps).  Alternatively, within the tournament Polar develops a Bluetooth Good succesful tool (which they are saying they’re going to do), then it might paintings simply nice with that.  Extra on that later.

Now that we’ve were given that out of the way in which, let’s dive into the usage of it.

The use of with the 4iiii’s App:

There’s a couple of alternative ways you’ll use the Viiiiva, however I’m going to begin off with essentially the most typical approach, by way of the 4iiii’s app.  The App is loose at the App Retailer (iDevices simplest as of late).

When you’ve were given it spread out you’ll be capable of create an account to save lots of settings in.  It simplest takes a 2d.

From there you’ll hit the tab within the higher proper nook to look the entire choices.  For now, we’re going to dive into the only titled ‘Viiiiva Configuration’.

When you do this, you’ll be introduced right here.  That is the display that permits you to pass out and in finding your Viiiiva.  You’ll press the ‘Attach’ button to begin the hunt.  If for some explanation why you’ve disabled Bluetooth, it might now be regarded as vital trail to permit it.


Inside of 5-10 seconds it’ll come again with a list of within sight Bluetooth Good gadgets.  For many of you, you’ll simply see the underneath with a unmarried sensor discovered (the only categorised ViiiivaB9EC in my case).


In the event you occur to produce other Bluetooth Good gadgets round, you’ll see one thing like this:


Regardless of, make a choice the Viiiiva one and it’ll pass forward and hook up with it:


When you do this you’ll see the tool enumerated and that you’ll then pair to ANT+ gadgets.


Subsequent, we’ll faucet “Pair Viiiiva to ANT+ Units”, which initiates a seek of ANT+ gadgets for your neighborhood. For many of you, you’ll most probably simply have a unmarried pace/cadence sensor or energy meter.  Or for runners, an ANT+ footpod.

In my case each my motorcycle and The Lady’s motorcycle popped up within sight.  Needless to say ANT+ sensors go to sleep when now not in use, so give your motorcycle wheel or crank a handy guide a rough spin to turn on them.


When you’ve discovered a number of gadgets you’ll faucet the checkbox subsequent to them to ‘pair’ to them.  Since ANT+ helps a couple of sensors paired to a couple of gadgets, this may haven’t any affect in your present GPS gadgets (i.e. a Garmin).  They may be able to run similtaneously.


When you’re executed, then pass forward and faucet ‘Carried out’, which confirms it to reminiscence within the Viiiiva.  Subsequent we’ll dive into the usage of the app.

Word that should you’re doing a footpod, it’s precisely the similar procedure – simply choose footpod from the checklist:


What’s cool this is that you’ll pre-pair your other gadgets for each biking and operating.  In order that when the ones sensors turn on, it’ll routinely beginning passing information via on them – no wish to ever once more contact the config app.

Word that you’ll simplest pair a unmarried sensor variety although, that means pairing just one footpod, one energy meter, one pace/cadence combo sensor, and so on…


Now that we’ve were given the whole thing setup, faucet the menu button and alter to ‘Exercise’ mode (prior to now referred to as ‘Reside Information’).  This may increasingly carry you right here:


Prior to you get began, you’ll wish to temporarily configure you’re wheel circumference should you’re the usage of a pace sensor for distance.


You’ll be able to additionally trade from imperial to metric right here, and for energy meter customers you’ll begin an ordinary ANT+ energy meter calibration request.  Finally inside the settings you’ll give you the option to have the app routinely transfer between operating and biking mode dependent at the sensors activated.

As soon as out of the settings, there’s yet one more possibility – which is whether or not or to not use GPS for distance/pace.  You’ll be able to see the little GPS on/off button.  Inside of, I’d pass with off.

With the whole thing set, we’re able to journey!  To start out, simply hit the ‘Get started’ button.


You’ll see that my energy, cadence, and pace are all appearing up.  Word I’ve were given no ANT+ adapter hooked up to the telephone, the whole thing is simply routing throughout the Viiiiva.

If I wish to create a lap, I will merely faucet the lap button, which resets the timer and marks a lap within the report for later research.

Or, in my case, I will simply proceed to journey on.


As soon as the journey is entire I hit ‘Prevent’ to pause the timer.  You’ll be able to press begin to resume once more.

As you’ll see, the knowledge is sort of similar to that of my Garmin.  You’ll see the HR values (present) are just about similar (they differ inside of 1-beat of one another), and the ability averages are inside of 1w (utterly commonplace for various head devices even recording the similar circulation), and after all my distance is identical – however I had the Garmin set for a quite other circumference.


When I’m executed with the journey, I’ll faucet ‘Save’, which makes it to be had inside the historical past menu.  The historical past menu will display all historic rides (or in my case, all rides since I had ultimate loaded a distinct beta app to check new pieces).


From an iPhone perspective, whilst indoors you’ll position your telephone any place within sight and it’ll pass forward and file and relay the knowledge.  In my case I simply put it in this instructor stand I constructed that you just see above somewhat.

Outdoor, I typically depart it both in my again pocket, or on an armband that’s in a different way beneath my jersey.


However there’s a groovy trick that’s now not widely recognized.  In the event you don’t care in regards to the HR portion, you don’t in fact must put on it.  The Viiiiva will routinely stay the relationship at the Bluetooth Good facet alive so long as the ANT+ information continues to circulation information.  Which means that so long as your energy meter, footpod, pace/cadence sensor ship information, Viiiiva will proceed to relay information.  Most often, that’s every time you’re actively doing one thing with it.


So you’ll in fact toss simply the transmitter pod in a motorcycle bag after which have the knowledge circulation in your telephone that means.  The one factor you wish to have to do is to wake-up the Viiiiva.  To take action, simply rub the 2 contacts:


Then, simply stash it any place you wish to have.  That may be for your again pocket, or in a motorcycle bag, or duct taped to the handlebars.  No matter floats your boat.


As soon as e-mailed to your self you’ll take a look at the knowledge for research in any program you notice have compatibility.  It’s same old .FIT report formatting, which is identical that Garmin and plenty of different corporations use nowadays.  So you’ll add it to Strava, Garmin Attach or somewhere else.

Right here’s a pattern report from Garmin Attach of the Viiiiva information paired to the Quarq.


And, right here’s the similar report from the Garmin Edge 800 paired to the similar Quarq unit:


In evaluating the information in additional element, I’m discovering them just about similar.  With energy meters, you in reality wish to take a look at whether or not an app is processing the knowledge as it should be.  To that finish, there’s open-source energy meter head unit exams evolved by way of Quarq that a lot of the business is the usage of now (without reference to which energy meter you hook up with).

In speaking with 4iiii’s, they’ve handed all however one of the vital exams (Check #3), and for that check they’re taking a look to factor a repair within the coming days.  That exact check isn’t an enormous worry although because the situation is basically overlaying a case the place somebody is pedaling at sub-60RPM  and a worth isn’t written till the top of the stroke (which at say 20RPM could be 3 seconds later).  In apply, this can be a beautiful excessive edge-case, and to in reality see the affects you’d should be making a fairly large leap in wattage as neatly.  However, a repair is coming for an issue that I’d wager affects .0001% of the inhabitants.



Subsequent up, operating!

This will likely be faster, since we’ve already coated the configuration and setup.  In operating mode, you’re principally speaking in regards to the ANT+ footpod, after which after all the center price data equipped by way of the Viiiiva strap itself.

Word that you’ll configure the calibration of the footpod inside the app if you recognize your calibration price.  Since you’ve got an ANT+ footpod already, that most likely method you’ve got an ANT+ show unit (i.e. Garmin watch), so you’ll simply glance within the settings there and re-type the four-digit calibration price.

Assuming your footpod is unsleeping, you’ll see ‘0’ displayed for cadence should you’re status nonetheless originally of a run.


As we begin to run you’ll see my tempo, middle price, and cadence information is all displayed – at the side of the space.  In my case I’ve decided on to nonetheless use GPS information, however cadence is coming from the footpod.


You’ll see I nonetheless have the potential to set lap markers as neatly right here by way of urgent the large lap button.


When I’m executed with the run, I will press the prevent button and practice the similar process to save lots of the knowledge and e mail it to myself.

Preferably I’d like to look some integrated sharing choices inside the app itself so I may save the hassles – as an example, posting without delay to Strava or Garmin Attach, and so on….

As soon as posted, you’ll see the run information similar to some other:


Of specific observe this is the the cadence information from the footpod, and the lap information from me urgent lap button, each sporting via.


Astute readers will realize there used to be a HR strap spike on this report – the place it spikes upwards of 210bpm (the spikes later within the report are right kind as I used to be doing periods).  I requested 4iiii’s about this, and so they’ve made some firmware adjustments since this actual run with the intention to higher filter those faulty spikes.  In newer checking out I haven’t noticed any problems.


General, this can be a nice approach for purchasing footpod information into your telephone if you have already got a ANT+ footpod.  Word that this isn’t only for out of doors operating, but in addition indoor/treadmill operating the place it’s maximum acceptable.

At this time the one footpod available on the market that’s Bluetooth Good is the brand new Polar Bluetooth Good footpod, however that’s beautiful large in comparison to the ANT+ editions which can be the scale of 1 / 4.  So this is helping bridge that somewhat.

Working out the other modes the Viiiiva strap transmits in:


Now that you just’ve were given a take hold of on how the platform works when it makes use of all 4iiii’s elements, let’s dive into somewhat extra element at the other modes Viiiiva helps – in the long run segueing into third birthday celebration make stronger.  Working out those modes is important to getting correct information – particularly for energy meter customers.

When the Viiiiva strap announces your ANT+ information again out as Bluetooth Good, it’s doing it the usage of Bluetooth Good tool profiles.  Those are standardized, and neatly understood – merely strategies of transmitting a given form of data (i.e. middle price information, or energy information, or cadence information).  Usually, maximum sensors simplest transmit one form of information at a time.  A middle price strap transmits middle price information, and a pace sensor transmits pace information.  And for the reason that, they’re simplest the usage of one tool profile at a time.

Since they’re simplest the usage of a unmarried tool profile at a time, apps and gadgets see the sensor information from a unmarried particular ID (a GUID technically, however call to mind it as a telephone quantity).  The Viiiiva strap simplest has one telephone quantity (in impact) and will simplest take one name at a time.  So, what occurs when you wish to have to have two channels of data equivalent to energy and middle price?

Smartly, let’s first beginning with the most simple operation – simply transmitting middle price information.  If that’s the case, the Viiiiva strap isn’t doing any ANT+ conversion, however somewhat appearing as an ordinary Bluetooth Good middle price strap.  Most significantly although, it’s simplest handing over a unmarried information channel: Center price data.  So apps paintings nice and the paintings is going round.

Now we layer in energy data.  If that’s the case, the 4iiii’s builders had been in somewhat of a pickle.  How do you get two times as a lot data while you’ve already were given a unmarried ‘telephone quantity’ taken up?  Smartly, they went forward and added further channels of data.  The telephone quantity stayed the similar, however extra information used to be layered on best.  The issue this is that apps have to understand to search for the extra information channel.

Now what occurs in the event that they (third birthday celebration apps or gadgets) don’t find out about that information channel?  Smartly if that’s the case the Viiiiva strap is going into alternating mode.  It transmits one information channel (i.e. middle price) for a 2d, after which shifts and transmits the following information channel (i.e. energy).  Rinse and repeat perpetually.  However what’s the issue there?  Smartly, you get part as a lot information.  For middle price customers, that is probably not terrible, however for energy meter customers, that’s as unhealthy as creating a care for the satan.

So the place does that put us?  Smartly, two modes that the Viiiiva helps:

1) Complete Compatibility: On this mode, the third birthday celebration software or tool has been up to date to know the a couple of information channels and can obtain all information channels similtaneously with none lacking information

2) Rotating Compatibility: On this mode, the third birthday celebration app hasn’t been up to date but, and thus will obtain a rotating (round-robin) information set, ensuing within the other sensors rotating live-data to the appliance.

Now you notice the significance of getting complete compatibility.  Clearly, the default Viiiiva app has complete compatibility.  From there, we take a look at the third birthday celebration apps.  4iiii’s has evolved an inventory right here of absolutely suitable apps [PDF], however in the long run as shoppers we wish to see each and every app as it should be parse the a couple of channels of data.  The checklist of apps examined with no less than middle price compatibility is right here.  And after all, for builders, you’ll beginning right here.

The excellent news this is that the business goes to drive this factor beautiful temporarily.  Different merchandise like the brand new/up to date Bluetooth Good PowerCal from PowerTap want this similar capacity to ship energy information along middle price information.

A temporary take a look at third Birthday party Apps:

Now that I’ve coated the other modes to be had, let’s take a short lived take a look at how this works in apply.  First up I’ll take a look at a running-focused app – iSmoothRun.  This app helps the Viiiiva absolutely, and does right kind parsing of knowledge from each channels, so it doesn’t must skip information issues.

Putting in the app you’ll dive into the ‘Settings’, the place you’ll see the 4iiii Viiiiva indexed:


While you faucet on that it’ll pass forward and seek for the Viiiiva, in the long run discovering it:


When you faucet at the Viiiiva it’ll display you the configuration choices.  You’ll be able to see that it helps each biking and operating sensors.  Maximum notable you’ll choose whether or not the space comes from the stride sensor or the GPS.  The quantity you notice above (1.012) that atmosphere is the calibration issue.


In my case, I left the space off, however sought after cadence.

From there I went forward and created a brand new free-workout operating job.  Mainly a non-structured exercise to file information:


As soon as operating, you’ll  see my cadence indexed underneath, in addition to the center price coming from the strap.


If I transfer into a distinct view, you’ll see extra averages.


The app helps splits as neatly, permitting me to separate up chunks of my exercise.  Inside of that you just’ll once more see the cadence and middle price information coming from the Viiiiva.  If I had set it to off for GPS, you’d have the tempo/distance information as neatly from Viiiiva:


When I’m executed I will save the job and export it to a slew of various services and products:


As you’ll see, it’s all beautiful immediately ahead and works precisely as you’d be expecting for an up to date app.

Now, let’s see the way it works inside of a non-updated app.

I’ll check out the default Wahoo Health app for a biking exercise.  Most often talking that is my go-to app for any health information recording job at the iPhone, because of it having in reality excellent information cleanliness/processing practices and third birthday celebration integration.  On this case although, it doesn’t but make stronger the multichannel information streaming that the Viiiiva supplies, so it has to make use of the round-robin approach.  On this check, I had already setup the ability meter inside the 4iiii’s app, after which pressed the ‘Unencumber Viiiiva’ button in order that different apps may use it.


Then, over within the Wahoo app I went forward and created a brand new job profile and referred to as it ‘4iiii’s Viiiiva’.  You’ll be able to name it Macaroni should you’d like although:


Subsequent, I tapped to pair the HR and Energy Meter sensors.  You’ll see the ability meter sensor pickup first:


Then, a 2d later you notice the HR sensor remove darkness from:


Now take note I’m about to turn you an instance of an app that isn’t but up to date for dual-channel make stronger.  Thus in impact, I’m appearing you the non-ideal situation.  I don’t imply to pick out on Wahoo, it’s only a transparent and easy instance.

After beginning an job, you’ll see the center price information streaming into the Wahoo app.  Alternatively, you’ll observe that the ability information is lacking – appearing null:


Then, a 2d or two later, the ability information will seem (on this case, a very easy pedaling of 72w), but if it does, the HR information remains stagnant.


This round-robin will repeat time and again.  Because of this, your whole information issues will most likely display part in their exact price (and even much less, should you round-robin in different gadgets).  From an influence meter perspective, this makes the tool unnecessary – as energy meter information is all about having as correct information as conceivable.

The excellent news this is that I feel we’ll see adjustments to apps, most commonly since the wave of coming near near Bluetooth Good gadgets will just about call for/require it.  As an example, CycleOps has introduced a Bluetooth Good variant in their PowerCal middle price strap, that may in flip be transmitting each energy and middle price information – thus requiring the similar compatibility ranges.

I’ve showed with Wahoo that they do plan on imposing make stronger for this situation, inside of their apps, however don’t have a timetable but for doing so.  That will additionally most likely imply imposing it inside of their API’s, making it near-instantly to be had for 150+ software builders in the market at the Apple platform (just about each and every software at the iOS platform as of late that does ANT+ or Bluetooth Good well being information makes use of the Wahoo Health API’s).

An excellent briefer take a look at Bluetooth Good third birthday celebration tool make stronger:

I used to be sorta excited to put in writing this segment, as I believed I’d be capable of display some cool product integration that this might permit.  Except for, in spite of everything, there’s in fact not anything as of late to reveal.  The whole lot remains to be within the ‘doesn’t but paintings’ degree, now not in the course of the fault of 4iiii’s or the Viiiiva strap, however merely on account of {the marketplace} nonetheless now not having any non-phone gadgets that in fact make stronger Bluetooth Good equipment apart from the Bluetooth Good middle price strap.  Or even then, that’s extremely restricted.

(Word: The entire underneath gadgets aside from the TomTom make stronger ANT+ and thus make stronger the Viiiiva HR by way of ANT+, this segment is solely speaking in regards to the Bluetooth facet of items.)

In many ways, Bluetooth Good is the the child that everybody needs to name their good friend, however no one in reality solutions the telephone after they ring to play.

As an example, I sought after to take a look at it with the Leikr GPS watch, however as of late in beta that doesn’t but make stronger Bluetooth Good connections:


After which I sought after to look if the TomTom Multisport unit would display the possible right here, however one thing isn’t moderately running in the market and it wouldn’t pair.  Since that product remains to be in beta (TomTom Multisport), I’ll allow them to type it out – I’m certain they’ll get it found out in a while.  However that may no less than permit people changing from ANT+ primarily based gadgets (i.e. an older Garmin watch) with the ANT+ pace/cadence sensor to transport over to the TomTom unit with no need to shop for a brand new cadence sensor.


And naturally, I will’t use it with the Garmin Edge 510/810, since whilst they have got Bluetooth, it’s old-school Bluetooth, and now not Bluetooth 4.0, and thus now not Bluetooth Good suitable.


And after all, whilst the Garmin Fenix has Bluetooth Good, it doesn’t make stronger Bluetooth Good equipment.


Alas, for now, you’ll must stay ready.

In reality, the one tool that it does no less than connect to as of late is the now-discontinued Motorola Motoactv (only for middle price).  However for the reason that tool has each ANT+ and Bluetooth Good already, it doesn’t in reality lend a hand a lot there.  And figures that the one tool that works is the one who’s discontinued.

However I believe as we hit Eurobike and Interbike in past due August and mid-September respectively, that you just’ll begin to see Bluetooth Good gadgets hit the marketplace that may take inputs from Bluetooth Good equipment.  As I famous previous, Polar has lengthy mentioned it’s plan to transport to Bluetooth Good (for 2 years now) – so I’d must think that their subsequent liberate of gadgets (every time this is, I don’t know) would come with make stronger for Bluetooth Good equipment.  Much more so since they not too long ago launched the Bluetooth Good footpod, after which have prior to now launched each the H6 and H7 Bluetooth Good HR straps.

As soon as we have now gadgets that make stronger Bluetooth Good profiles equivalent to pace/cadence, and gear meters, then we’ll begin to see the true energy of the strap – equivalent to with the ability to path ANT+ energy meters to non-ANT+ motorcycle head devices.

Common Upkeep: Firmware Updating and Battery Swapping:


The Viiiiva firmware is updatable, and over the process the previous few months they’ve made updates to the firmware of the center price strap transmitter pod.  Those updates have so far focused on minor trojan horse fixes, however long run, it will additionally carry new options (loose or paid).  The explanation they might wish to come with options within the firmware as an alternative of the app is that the center price strap is designed to paintings with out connectivity to the app (aside from for preliminary configuration).

The method is moderately immediately ahead.  When a brand new firmware replace is made to be had, the Viiiiva app will notify you that it wish to replace the firmware in your Viiiiva:


Assuming you press ‘Sure’, it’ll then obtain the firmware from the interwebs.  This simplest takes a 2d.


Following that it’ll set up the firmware.  This takes possibly 20-30 seconds to finish.  The little 4iiii’s brand will fill-up with grey as the share will increase.


After that, the strap will reset itself and also you’re excellent to move.  No settings are misplaced right through the firmware replace (no less than, none have for me to this point).

Converting the battery is set so simple as it will get with an electronics tool.  You received’t wish to do it incessantly although, about each and every 200 hours of energetic use.  First up, you’ll want a CR2032 battery (in most cases $2-3US).  Given the sheer amount of gadgets I check, I purchase them in bulk (all $9 of them!).  You’ll additionally need some form of straight-blade screwdriver, knife, or, in my case, a random motorcycle tire-iron I had inside of succeed in.


Merely twist the battery and it will have to come out.  If now not, simply flip it over.


Inside of you’ll see the outdated battery putting out.


Unload the outdated battery out and toss.


Plop the brand new one in and tighten again up.


Venture entire!

On the whole, the way in which I do know the battery goes is that the tool will pair to start with, however you then’ll see it drop out.  That is beautiful true of virtually each and every CR2032-powered sports activities accent/tool I’ve examined.  The tell-tale indicators are random drops in information (right down to 0), particularly somewhat into the job.  I all the time stay a couple of CR2032 batteries available, and one in my backpack and suitcases for after I’m travelling.

The Long term and Doable:

What’s attention-grabbing in regards to the strap is the firmware updating side. I chatted with 4iiii’s round what they’d at the radar for the long run.  Right here’s the place issues stand for Q3 (the following 2-3 months more or less).  Word that those may finally end up being paid options, principally paying a small charge to unencumber those further features, sorta like in-app purchases works as of late for getting further ranges in video games.

– Obtain .FIT information without delay from Garmin gadgets to iPhone (by way of Viiiiva)
– Viiiiva report saving – the power to save lots of information to the strap without delay from ANT+ sensors (or HR) with no tool, as an example, right through swimming or simply out climbing for an afternoon, then obtain later
– Upload Health apparatus profile for workout apparatus, enabling customers to sync to gymnasium apparatus with “ANT+ Hyperlink right here” brand (eg. BodyBike, Concept2, Nautilus, Schwinn, Startrek, Tacx, and Woodway)
– Stand by myself Liiiink Mode without a Center Fee, supplies cast pass-thru of energy as an example.  Thus no rotation of knowledge to the telephone should you don’t need HR, ultimate for non-conforming apps
– Auto-Calibration for Energy Meters (Auto-Calibration serve as works on its own in Viiiiva, however isn’t prolonged but to third birthday celebration apps by way of Viiiiva)

Long run, they’re taking a look to leverage the integrated accelerometer that the Viiiiva in fact has in it (permitting them to hit upon movement and orientation).  This may permit the next situations:

– Process Tracking
– Cadence/Step Counting (Operating & Strolling)
– Person programmable Tip-Faucet: This may permit the power to easily faucet the HR strap to cause occasions in an app, equivalent to laps, converting display show, or anything an app sought after to cause.

On the similar time, they stressed out that as a fairly small corporate (in comparison to say, Garmin or Polar), they had been in reality searching for situations that customers had been considering and recognize any comments.  I’m excellent with concepts being dropped underneath within the feedback.



I’ve been serious about the Viiiiva strap since I first heard about it just about a yr in the past at Interbike.  Whilst they launched it again in February, it’s in reality been within the ultimate month or in order that I think the insects had been labored out, and that it’s reached a degree of adulthood the place I will now suggest it.

From a knowledge perspective, the local app could be very cast – and I’m not seeing problems I noticed again within the previous releases.  Particularly for cyclists, which is the place I’d in reality suggest this product (and particularly, the ones energy meter customers in the market).  Taking a look down the street, I’m positive this tool will most likely force extra cross-platform integration – which is a great factor for shoppers.

For the reason that the unit follows the entire Bluetooth Good specs, it enjoys beautiful large third birthday celebration make stronger within the app international for middle price information.  As a basic rule of thumb, if the app helps the Wahoo Health (indexed on their web site), this tool will no less than paintings with it from a elementary capability perspective (HR + rotating information from sensors)

The one space this is problematic alternatively is the loss of make stronger from third birthday celebration apps at the complete dual-channel make stronger (i.e. greater than two gadgets paired directly).  As famous, just a few apps make stronger that as of late, and I’d in reality like to look that grow to be common.  I’m now not extraordinarily apprehensive there, as a result of in the long run, the ones apps could have to take action since tool adoption within the Bluetooth Good house on the whole will force that.

As the ones packages replace, I expect we’ll see Viiiiva grow to be core to bridging the distance between ANT+ and Bluetooth Good gadgets for moderately a while.

Right here’s my take a look at the Professionals & Cons:


– Converts ANT+ accent transmissions to Bluetooth Good simply
– As it should be data information, particularly energy information
– Provides you with each ANT+ & Bluetooth Good HR strap (can use similtaneously)
– Can use with present ANT+ show gadgets for middle price


– Doesn’t but have large third birthday celebration make stronger for all complete multichannel transmission mode
