rfcomm bluetooth permission denied error raspberry pi
<p>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 <a href="http://people.csail.mit.edu/albert/bluez-intro/" rel="noreferrer">http://people.csail.mit.edu/albert/bluez-intro/</a> tutorial. I got the simple RFCOMM and L2CAP protocols working. I'm having trouble running the SDP protocol. The server code is - </p>

<pre><code>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()
</code></pre>

<p>The error I'm getting is -</p>

<pre><code>Traceback (most recent call last):
  File "rfcomm-server.py", line 7, in &lt;module&gt;
    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')
</code></pre>

<p>Here are some steps I have taken-</p>

<pre><code>Add the user 'pi' to lp group
run piscan on hciconfig hci0
Add --compat option to bluetoothd in bluetooth.service
</code></pre>

<p>Any help would be appreciated. Thanks!</p>
