Junk when running discover

[wxor]

Having a problem when running discover after a hijack. "@> b'SP'" looks to be echoed back on to the cli and after about 30secs there is a "L2CAPException". It also takes a few attempts to hijack. Thanks in advance, love your work. Your DEFCON26 talk was awesome :)
