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-se         


        

Answer 1

I ran the same problem even after @GozzoMan's solution because /var/run/sdp file was not being generated at all after calling sudo sdptool add SP. The problem was the location of daemon service file was different on my system (Raspbian Buster on Raspberry Pi).

If you experience the same;

• Check the status of bluetooth daemon and look for the service file path (2nd line)

sudo service bluetooth status

# alternative: 
# sudo systemctl status bluetooth

In my case the service file was run at /lib/systemd/system/bluetooth.service, NOT FROM /etc/systemd/system/dbus-org.bluez.service.

• Then modify the correct file (which was /lib/systemd/system/bluetooth.service in my case) to add -C to the ExecStart=/usr/lib/bluetooth/bluetoothd line as instructed in the previous answer.

• Do not forget to reload daemons and restart bluetooth service before running sdptool:

sudo systemctl daemon-reload
sudo systemctl restart bluetooth

sudo sdptool add SP

Now /var/run/sdp should be generated.
