I'm using a bluetooth dongle to try and send information from ubuntu 15.04 to raspberry pi b+ running the latest debian jessie image. I'm just following the http://people.csail.mit.edu/albert/bluez-intro/ tutorial. I got the simple RFCOMM and L2CAP protocols working. I'm having trouble running the SDP protocol. The server code is -
from bluetooth import *
server_sock = BluetoothSocket(RFCOMM)
server_sock.bind(("", PORT_ANY))
server_sock.listen(1)
advertise_service(server_sock, "SampleServer",service_classes=[SERIAL_PORT_CLASS], profiles=[SERIAL_PORT_PROFILE])
client_sock, client_info = server_sock.accept()
print "connection from: ", client_info
client_sock.send("PyBluez server says Hello!")
data = client_sock.recv(1024)
print "received: ", data
client_sock.close()
server_sock.close()
The error I'm getting is -
Traceback (most recent call last):
File "rfcomm-server.py", line 7, in <module>
advertise_service(server_sock, "SampleServer",service_classes=[SERIAL_PORT_CLASS], profiles=[SERIAL_PORT_PROFILE])
File "/usr/lib/python2.7/dist-packages/bluetooth/bluez.py", line 176, in advertise_service
raise BluetoothError (str (e))
bluetooth.btcommon.BluetoothError: (13, 'Permission denied')
Here are some steps I have taken-
Add the user 'pi' to lp group
run piscan on hciconfig hci0
Add --compat option to bluetoothd in bluetooth.service
Any help would be appreciated. Thanks!
This solution worked for me:
sudo chmod o+rw /var/run/sdp
