Hello,
It's been more than three weeks that i've been freaking out about this crash that occurs while establishing a BLE connection to a peripheral, scan wifi networks and connect to one of them via BLE.
Here is the crash's stacktrace and I hope that I can get some help in order to resolve this ungoing crash :
