Error when starting service

[wishbone1138]

I'm getting stuck on a attribute error when it tries "starting service". It pairs with my slave fine and looks up all the info it seems to need. I get a pairing successful message on my slave. It looks like it's having an issue polling the services?

I'd love to get this working as it's the only MITM BDR/EDR tool that I know of!

So "running ['hciconfig', 'hci0', 'piscan']" returned this object:

{'protocol': None, 'name': None, 'service-id': None, 'profiles': [], 'service-classes': ['1200'], 'host': 'E4:22:A5:0B:DF:8B', 'provider': None, 'port': None, 'description': None}

And the protocol is None and the script expects it to be a string, hence failing at if service['protocol'].lower() == 'l2cap. I suggest running hciconfig hci0 piscan to see if that is the correct results the parser is getting. If not, patch the parsing of the commands output. If already correct, figure out if RFCOMM or L2CAP is the protocol to be used. Then patch the script at mitm.py:260 to use the right protocol.
