It seems like when your phone initiates a connection something is not working properly. could you please repeat pairing procedure when PC initiates a connection and send me HCI dump? i just want to see the message sequence.

It's comparable to ordinary modem. cool, so seems like you got advertised 43kbit/s = ~5.4 kBytes/sec (if you consider overhead on L2CAP/RFCOMM/PPP/IP/TCP/HTTP :) > I putted together a webpage where I wrote step by step what I had to do > to get this working.
