Wahoo tickrx HRV

Really all you need to do is to put on the strap and it will go into its pairing mode with the blue light flashing and then tell your watch to look for sensors. After that you can start an activity and look for the banner that says Ext HR monitor connected.

I use the Tickr X with Elite HRV so it should work work well with the app you're using as well.

Thanks for the reply.
I did a run this morning.

Got all the information you mention. However, you don't bother verifying that the strap actually records r-r data? And records it well and accurately ?

do you mean you want it to record HRV data to use in a 3rd party app after your run?

If so you might want to check Settings, Physiological Metrics and enable Log HRV if not already done so

Thanks for this tip.
Primarily, I want to make sure hrv is well recorded with an adequate frequency. Because garmin is a bit low on explanation about how hrv is used for training status,lactate treshold, recovery,... Same on wahoo side they don't provide (to my knowledge) the accuracy and frequency compared to a lab test fort example.

AFAIK the Wahoo tickr X doesn't send (correct) r-r info over ANT+ (unless they fixed that) It however does send it over bluetooth. You might try connecting over bluetooth and see if that changes anything.

According to Elite HRV only the Wahoo BLE signal is HRV accurate (the ANT+ is only HR accurate):

I could not find any other sources confirming this but this is probably good enough reason to connect over Bluetooth.

Ok. Again thanks for the precise information.

Now, how can I be sure the tickrx is connected to my watch via BLE or bluetooth and not ANT+ ?
Sorry but I couldn't find this information on my own ...

Look at the status when connected, BLE=Bluetooth, ANT+=ANT+

Thanks for this. I was using the TickrX with Ant+ for the Garmin HRV stress test, and always getting very high stress numbers.

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?
