I have now currently 3 devices that are being read with the Bridge and have run in a strange issue - sometimes some devices stop responding (not always the same one, though some more often than others).
But its immediately fixed with restarting the waveplus bridge python script.
so for now, I just have a cronjob that restarts it hourly...
I realize this is difficult to diagnose, with all the variables of different hardware, range and bluetooth in general...
maybe you have some idea though ?
