Hello,

I had a crash with this stacktrace:

Right before I did several BleManager.writeCharacteristic() with the data param containing 180 bytes

I have asked internally about this, do you have any other info to share?

I haven't found a way to easily reproduce.
Info: I save the log in a database before logging it with Timber.
I removed the override from BleServerManager.log() and BleManager.log() and I haven't noticed any crashes for the last 24 hours.
I will continue in this direction.

Regards,

Thibaud

Hi Thibaud, 

Not sure what to recommend so have asked internally and will update if I have something.
