Pair code is not used by my plugin (altough it used to be in the ini file). I tried for a while to get that part working but gave up and thought it was ok to just pair the phone in Bluesoliel instead. Have you done this?
It may also be worth setting your debug level to 5 in the ini file and rerun. It gives more info and may give you some better ideas.
edit: Looking more closely at the error its still something to do with your address. I think its a pairing problem rather than a code problem. Have a look in the bswrapper.log as well. That may help. There is a debug level setting for that too so set it to 5 and rerun (it in the bswrapper.ini file)
