I’m having some issues with Bluetooth on the Beaglebone Green Wireless. The wl18xx module seems to stop working after a period of time (still trying to work out exactly how long). It doesn’t start working again until I power-cycle the board.
I’ve managed to reproduce the issue with a fresh BBGW (straight out of the box) with the latest image from beagleboard.org ( AM3358 Debian 10.3 2020-04-06 4GB eMMC IoT Flasher) and no modifications.
Steps to reproduce:
- sudo hcitool lescan
- leave it running
- wait about 20min
Output stops. Running sudo hcitool lescan again has no output. Restarting the board is the only way to recover.
I also noticed that the wifi AP also goes down at the same time which seems to indicate it’s an issue with the wireless module.
I found one other person who had similar issues but no solution:
There’s nothing remarkable in the logs at the point where it fails that I’ve been able to see.
Is there anything else I can try?
