I'm trying to set up tethering for my Zero with an Android phone. So far I can login and use the terminal over Bluetooth but now I would like the Zero be able to access the Internet but I get this message: 'failed to obtain ip address on bnep0'. This is what I have done so far: go to Bluetooth manager in GUI mode, click 'Devices', right-click on the device then select 'setup', chose 'Connect to group network'. First a message says 'Device added successfully' but then it says 'failed to obtain ip address on bnep0'. Do I need to add bnep0 in /etc/network/interfaces with an IP address?
@goldilocks is right, the phone needs to provide IP address. Android setup: Settings -> Tethering & portable hotspot -> Bluetooth tethering ON
Once the BT tethering is on, the RP can connect (use the Bluetooth manager).
