Hello, can someone please post the sucessful 'rf_conn' dump with debug switch on, so we can compare the packets exchanged(UI, UIH, PN, etc...) on our respective platforms. This would be a great help for those trying to debug RFCOMM.

Hello, I have even sent an e-mail concerning this subject but no answer and it is quite urgent for me. The problem : I am using a digianswer PC card (commercial version) on omnibook PC : this is the master. I am using CSR HW driven by an ARM (containing AXIS stack : version should be something like 20010108) : this is the slave. I first search for services with the PC on the remote CSR HW. I found audio and serial :-). That is to say SDP is Ok as well as L2CAP since I established the SDP connexion ! Then I try to connect to remote COM port (RFCOMM). The L2CAP connection/configuration is OK, the PC card sends a SABM packet and I answer with a UA (which is acknowledged). BUT, that's all ! The connection hangs and a message is displayed on the master Screen (PC) : "failed to open com port..." I used a protocol analyser to check what was wrong but I did not find anything : It is exactly the same packets which are exchanged between two digianswer PC cards and the configuration I have talked about above. the different is that the RFCOMM connection establishment does not stop just after the UA packets... Is this an interoperability problem ? Is there anyone who has tried such a connection ? (commercial product versus Axis Stack driving other hardware ?). Do you think Digianswer is not totally "opened" ? Thanks in advance. Please do not hesitate to contact me would you require any further information (e.g I can send yoo excell files which includes the packets exchanged in the two cases...) Best regards.
