@isazi Hi, I want to add my point of view.
I have Suunto Race and I was testing the connection today, since a big race is coming. Until now, I was not using the HR sensor for races, but now I was curious. My HR strap is unfortunately not waterproof enough to wear during the swim. Therefore, I tested, if I can connect it after the swimming part. Once I ended the swim in Triathlon sport mode, I turned on the HR strap. The watch beeped and the strap seemed connected. But, when watching the HR, once I removed it from the wrist, HR vanished. This means, even if the sensor is apparently connected, it still shows the HR data from the watch optical sensor. That’s what I am asking: Is it possible to somehow change the settings to show the HR from the strap rather than watch?
Thanks!!
