Hi everybody,
I am developing a free/open source implementation of HDP using sancane's MCAP
implementation. I am using ERTM and STREAMING mode provided by Gustavo's
patches from 3th October. I've been testing my implementation between two
computers (both of them using the previously mentioned profiles). This test
seems working correctly but I am also trying to test it against a Nonin Onix
II 9560BT PulseOximeter (certified by Continua). This device is using HDP but
when I try to test my HDP implementation I've observed that the MCAP control
channel L2CAP connection is not correctly opened (see trace bellow)

There is a thread waiting for incoming connections on this psm, but it is
never waked up from the recv system call.

This part of the trace is repeated until local host closes L2CAP connection.

What am I doing wrong? Why the connection to this socket is not finished?
If you are interested in the complete trace I can send it to you.
Thank you very much.
Regards.
Jose.
