How to send BluetoothRFCommSocket with Scapy?

I set up a BluetoothRFCommSocket with this code:

    from scapy.layers.bluetooth import *
    from scapy.all import *
    bt = BluetoothRFCommSocket('68:A0:3E:CC:24:06',2)

And the error is:

    Traceback (most recent call last):
      File "test.py", line 3, in <module>
        bt = BluetoothRFCommSocket('68:A0:3E:CC:24:06',2)
      File "/usr/local/lib/python2.7/dist-packages/scapy-2.4.3rc1.dev120-py2.7.egg/scapy/layers/bluetooth.py", line 1229, in __init__
        s.connect((bt_address, port))
      File "/usr/lib/python2.7/socket.py", line 228, in meth
        return getattr(self._sock,name)(*args)
    socket.error: [Errno 22] Invalid argument

What is the correct way to set up BluetoothRFCommSocket and send it?

I also get this error.

From scapy source code:

class BluetoothRFCommSocket(BluetoothL2CAPSocket):
"""read/write packets on a connected RFCOMM socket"""

def __init__(self, bt_address, port=0):
    s = socket.socket(socket.AF_BLUETOOTH, socket.SOCK_RAW,
                      socket.BTPROTO_RFCOMM)
    s.connect((bt_address, port))
    self.ins = self.outs = s

Scapy uses SOCK_RAW to create the socket, but it seems like RFCOMM does not support this.(I have also tried to use c_types and libc, but the error still occured)

Replace SOCK_RAW with SOCK_STREAM will eliminate the error.This is the way PyBluez use.

(L2CAP support SOCK_RAW)
