This morning I did a HRV test with my 945 connected to my Tickr HRM in BLE mode (bluetooth) and got a really low result in the 20ies - i then disconnected and directly connected to the same HRM in ant + mode and got a high result in the 70ies. Pulse bpm was about the same during both tests. I did not move other than moving a finger to reconnect the Tickr HRM. This has to be a bug. Can anyone replicate this problem with a dual band HRM strap
