Wahoo tickrx HRV

This quote at https://elitehrv.com/ant-iphone-ipad seems a bit contradictory then
"If you want a heart rate monitor that is compatible with our app and also compatible with the other Garmin ANT+ products then we recommend getting the Wahoo TICKR because it has both Bluetooth and ANT+ so it can be used with your phone and your Garmin watch"
to "Only Bluetooth is HRV accurate, ANT+ is just HR accurate" on same site at https://elitehrv.com/compatible-devices

Whilst this maybe true (is it?) it seems odd to me. If a device can compute RR then how does it matter how it transmits said data. Clearly ANT+ devices can do RR as obviously the Garmin ones work.

https://www.dcrainmaker.com/2014/01/wahoo-fitness-tickr.html in the comments do sort of say this was true at least 2 years ago. If nothing has changed since then perhaps the Tickr isn't an ideal option for using with Garmin devices?

I guess "can be used with" just means you can get HR info.

I have used the TICKRX a bunch of times with Ant+, and haven't had any apparent issues just capturing HR. I don't typically log HRV.

But I have noted very high stress scores with the HRV stress test. After reading the post re the inaccurate HRV over Ant+, I ran an HRV stress test with an old Viiiiva strap, and got a very low number.

Doesn't prove inaccurate HRV with TICKRX Ant+ by any stretch, but makes you wonder.

Probably best to check with Wahoo support.

Probably best to check with Wahoo support.

So regarding the connection of TickrX to garmin 935 (and I guess other garmin watches supporting bluetooth), here is the procedure :

- Settings -> Sensors -> Add new
- Let the watch search for sensors
- Then when he has found the tickrX, the first one will be ANT+
You need to click on "show bluetooth sensors" to actually connect the tickrX via bluetooth and not ANT+

Regarding R-R data check, At the moment, I still don't know how to check the data correctness and accuracy. The only way I found to check R-R is transmitted is via the EliteHRV app on my phone. There, I get R-R readings (but don't know if they are accurate ...) and it is via bluetooth and not ant+

Firstly, you need to make sure that the RR is recorded in the FIT file: system->physiological metircs->log hrv

To measure the accuracy, you could use Firstbeat Sport analysis software. I believe they do a 15 day trial version.

I talked with Wahoo tech support.
Got the following clear answer

The TICKR X wasn't designed to support HRV, so it's not a matter of the HRM not working properly. This isn't a feature that we advertise or have put any work in to developing. We've heard reports of some apps like Elite HRV being able to calculate this data from the TICKR X. Although, the TICKR X doesn't transmit R-R data. This calculation is happening within the app.

Thanks,
Greg

So according to this person, wahoo tickrx is not designed to send R-R data. That's a bummer ... :)
According to another person from Wahoo tech support, discussion found on dcrainmaker comments section :

Hi Huub,

The TICKR does support RR/HRV via Bluetooth 4.0. There are a few apps on the iPhone that accommodate this. You will need to check with Polar to see if they have support for this. Please let me know if you have any other questions.

It seems to confirm R-R is only sent via Bluetooth

So now I shall run some tests with my garmin watch to see how it actually transmit R-R data. I will do that with Kubios software since it is free. Will keep you posted.
I will think after that if I have to exchange it against a garmin chest strap or not. However, to my knowledge, garmin HRM are not bluetooth enabled ... so no link to HRV4training and so on

Umm interesting - thanks for sharing. To me the latest response from Wahoo (which seems more relevant) suggests that it is not designed to work and there is no implication that it would but good luck to you if you get any meaningful results in any case.

Correct that the Garmin HRM-Run or HRM-Tri (best ones to use with a 935) are not BT enabled but equally you will know that they will work "properly" with the 935. Whether they also work with 3rd party apps is really more of an issue for those app providers.

I mentioned above how I believe you can record RR data in the FIT file the 935. As such if you feed that to these 3rd party apps then presume that is hopeful. Otherwise real time usage of 3rd party apps with 3rd party equipment is not a subject that has much merit talking about on a Garmin user forum.

No indeed but it would be useful if garmin straps could be used for everything ... As was the TickrX supposed to able to do, hence why I bought this one preferably. Will let you know!

No but it would have been a nice idea from garmin to make their HRM compatible to other apps. Two hits with a stone.
That is why I bought the tickrX in the first place, because I assumed I could use it with everything i.e. garmin watch & third party apps.
Will let you know about my research

Well TBH the one reason I also got a Tickr X was to be able to wear one HR strap when using Zwift running or cycling on a treadmill or Wattbike at my gym with an iOS device and still transmit HR to both Zwift and record on my Garmin. That said I have sometimes worn both a Garmin strap and a Tickr X so could get running dynamics as well but guess could now use the RD Pod. Training Status seems to have worked OK. You won't get VO2 Max updates on a treadmill anyway although don't think RR data is essential for that as you seem to get such updates from just OHR heart rate data.

What are you trying to discover from the RR data that the Garmin platform does not already do so?

Common sense suggests a company will make sure things work with its own products first and foremost and then follow standards (like the ANT+ ones) so 3rd party developers can hopefully use the data from them. There is of course the "competing" ANT+ or BLE communication protocols for devices like HR straps. Some have chosen one way or the other. You don't for instance see native ANT+ support in an iPhone nor a Polar device. Makes sense for Garmin to focus on ANT+ since they essentially own it but at least they are starting to allow BLE sensor connections although there is a big limitation with those in that you can only pair with one thing at a time so a BLE only sensor can never "work" in real time with both a Garmin and another other device regardless of who makes it.

TICKR Run ANT+

This thread explains why I get funny performance data when I use the TICKR Run HRM. I will try to connect by Bluetooth to see if that works.
