Closed sverrham closed 4 years ago
I'm experiencing stability issues myself, and this even before your refactoring.
It feels like it's an underlying problem, possibly with gatttool or one of it's dependencies. Looking at the error message, gatttool returns an empty byte, and this without an exit code, which leads me to think that it crashes the thread altogether.
Yes, maybe it is fixed now actually since we do not use a threaded reader, I don't remember if this included that.
I will see if it hapens again, but I think you are right that it probably is an underlying problem, maybe it will be fixed when the bluetooth driver is updated.
What I'm noticing after upping the log level for pygatt is that it seems to hang on this command, but only after a few times.

So my guess is that this is HW related, I have not had any issues with this running on my raspberry pi 4.
Or maybe it is a conflict on using the Bluetooth, I don't have anything else accessing the ble hw.
(Because of the covid-19 situation I do not have time to work on this much, maybe not at all next couple of weeks)

Closing since this seems to be an isolated problem
Crashed on my system this is running from my fork sverrham. trying to read data from an Airthings wave plus. Worked stable for 6hours before it crashed.
