Best advice is not to use it - at least not in a production environment. The driver that the Bluetooth relies on is very flaky (in particular the Broadcom driver). I discussed briefly with mr-manuel in the past 36 hours about it - it was never stable. Many people report that they can get a BMS working on the Cerbo with Bluetooth, but it randomly drops and never recovers unless you reboot - typically segmentation faults or "connection caused software abort" via the BLEAK module.

[Marvo2011]

Bluetooth is very complex, I got my JBD stable with my patch on a raspberry pi and an external usb device. I don't now if JBD has swapt the protocol with this new device. Has somwere more informations for this device ?

[warwickchapman]

@Marvo2011 May I look at your patch?

@IamSierraCharlie in the logs, it looks like it finds the device, but does not recognize it. I will try a Bluetooth dongle and see if that makes any difference.
