I'm not sure if it is relevant to your situation but on the Raspbery Pi 3 I need to apply the following patches to BlueZ 5.43 for the BCM43xx https://gist.github.com/pelwell/c8230c48ea24698527cd The issue I see without the patch is that the controller has an address of all A's in bluetoothctl. E.g: $ bluetoothctl [NEW] Controller AA:AA:AA:AA:AA:AA RPi3 [default] [bluetooth]# show Controller AA:AA:AA:AA:AA:AA Name: RPi3 Alias: RPi3 Class: 0x000000 Powered: yes Discoverable: no Pairable: yes UUID: Generic Attribute Profile (00001801-0000-1000-8000-00805f9b34fb) UUID: A/V Remote Control (0000110e-0000-1000-8000-00805f9b34fb) UUID: PnP Information (00001200-0000-1000-8000-00805f9b34fb) UUID: Generic Access Profile (00001800-0000-1000-8000-00805f9b34fb) UUID: A/V Remote Control Target (0000110c-0000-1000-8000-00805f9b34fb) Modalias: usb:v1D6Bp0246d052A Discovering: no [bluetooth]# exit [DEL] Controller AA:AA:AA:AA:AA:AA RPi3 [default] > > 3) Is there any thing to do with this HCI type for scanning? > > With Regards > Raja > -- > To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
