Nero and Power drop out during FTP testing using Bluetooth

[dwtrux]

I have tried to use the FTP test on the My E Training app on my iPad a couple of times with my Nero connected by Bluetooth to the Nero and to my Favero Assioma power pedals. Everything starts off fine but somewhere around the 18 to 19 minute mark of the warm-up period, I notice that my Power/Watts are stuck on one number and is no longer matching my Wahoo Bolt power and power is obviously no longer connected in the My E app. The time and speed seem unaffected.

It appears that somehow, My E Training is loosing its BT connection to either the Nero or the Favero power pedals mid ride. Anyone else experiencing such instability?
