No heart rate data with external HRM on Apple Watch

Steps:

  • Connect external bluetooth HRM (in this case polar’s arm band) to Apple Watch
  • Do a workout on Apple Watch using apple’s app.
  • Import to Strava

Workout on Strava did not contain any HR data! I do get HR data if i don’t use an external HRM though. If I look at the workout in the apple fitness app, i do see the HR data from the external HRM.

I believe this is an issue with Strava only selecting the HR data from the Apple Watch source. In Health App → Heart Rate → Data Sources & Access, you can see the Data Sources, including any external HRM.

 

Note: this happened today, but yesterday it did work.

Note 2: just did a test again and seems to work 💀still weird why that one run didnt

@Jana_S I suspect it can be fixed by simply re-importing the activity. I had one activity only upload partly once and when deleting it and then importing again, it was fixed.

To answer your side question: armband works great! AW stops using its own HR sensor and solely uses the armband. Only ‘issue’ i’ve had is that you have to manually connect it in the bluetooth settings, but once connected, it does not lose connection!

Hi ​@leonw, just out of curiosity, have you found out what the problem was? It might be useful for the next person looking for the solution of the same issue.

(And, a side question if you don't mind - how do you like the armband so far? Does it work well with the AW?)
