@michaeldwilson I will do so by the end of August. Now almost everyone is out on vacation. The sensor does not shut down (no zero reading). Instead it seems having a hard time reading the HR and for as long it keeps the last read value.
I guess with arrival of PXDZ.201119.005.A1 this one should be closed, it’s fixed
P.S. And thanks for all who contributed to the subject, I believe it helped solving the issue and workaround was really helpful in the meantime
