bluetooth.btcommon.BluetoothError: (2, 'No such file or directory')

Question

I'm simply trying to run the RFCOMM server example at https://code.google.com/p/pybluez/source/browse/trunk/examples/simple/rfcomm-server.py

$ python2 rfcomm-server.py
Traceback (most recent call last):
  File "rfcomm-server.py", line 20, in <module>
    profiles = [ SERIAL_PORT_PROFILE ],
  File "/usr/lib/python2.7/site-packages/bluetooth/bluez.py", line 176, in advertise_service
    raise BluetoothError (str (e))
bluetooth.btcommon.BluetoothError: (2, 'No such file or directory')

I am getting this error. My code is working on windows but I could not work Ubuntu 15.10.

Answer 1

I had the same problem on Raspbian, and solved by:

• Running bluetooth in compatibility mode,

  by modifying /etc/systemd/system/dbus-org.bluez.service,

  changing

  ExecStart=/usr/lib/bluetooth/bluetoothd

  into

  ExecStart=/usr/lib/bluetooth/bluetoothd -C

• Then adding the Serial Port Profile, executing: sudo sdptool add SP
