 Hi
I have problems with a connection through RFCOMM. I have ACL and L2CAP
channels but when I'm trying to make connection using RFCOMM it doesn't want
to answer - I mean remote BT device.
I'm sending SABM packet to start multiplexer working. According to
specification I should wait for UA packet but I can't get this packet.
Remote device is silent until it sends me disconnection request and is
closing ACL channel.
What can be the cause of this, why the remote device doesn't want to answer
with UA.
If any one knows why it's happening like this then please tell me because I
looked almost every where and I couldn't find a solution.
It's very important to me !!!

Regards

Maciej

please stop posting non BlueZ related question like this to our mailing
lists. I already told you that I am not going to answer them and as you
have seen nobody else do. Everything you need to know is written in the
Bluetooth specification and with hcidump you can see how BlueZ treats
RFCOMM connections.

Marcel
