Comment 42 for bug 1674509

@korad, well, i would assume that 90% of the IoT boards we will support will have such a UART based setup, so i would lean towards having generic serial tty support in the BT rules without having to define it for each single board in the gadget... i.e. simply by adding rw support for /dev/tty[A-Z]*[0-9] to the apparmor rules ...

else just installing the bluez snap on devices that didnt take that setup into account in their gadget proactively will simply not work.
