A Python interface for communicating with a Lego Mindstorms EV3 over RFCOMM.
Verify that your sdp includes an SP:
-> % sdptool browse local
...
Service Name: Serial Port
Service Description: COM Port
...
If you don't see an SP entry add one:
-> % sdptool add SP
Then:
-> % hcitool scan
...
XX:XX:XX:XX:XX:XX EV3
...
-> % sudo rfcomm bind /dev/rfcomm0 XX:XX:XX:XX:XX:XX
Now /dev/rfcomm0 can be opened and closed like a normal serial port. The opposite action is:
-> % sudo rfcomm release /dev/rfcomm0
