@jelkner I would rather have you working with us on the problem if you like. It might be some insights for you in how UT works, and for us an opportunity to recruit a new community contributor Would you mind bringing one of the OPOs back to Android, to see whats the MAC address there? We definitely need to find out where Android gets it from. Also for Bluetooth, see this bug: https://github.com/ubports/ubuntu-touch/issues/955
