[bluetooth-dev] rfcomm connection establishment / porting to arm
I try to port the stack on ARM7. I am working with CASIRAs and digianswer PC cards.
My configuration is the following :
- PC card is the master
- CASIRA is driven by the arm.
First I am looking for services on CASIRA (SDP) : I found serial port and audio.:)
Then I try to connect to the serial port : The L2CAP connection procedure is fine (connection and configuration). This is the second L2CAP channel( the first is for SDP).
I receive then a SABM packet to which I answer with a UA packet. Then I don't receive anything and the connection gets down.
As I got an analyser I checked that it was exactly the same packets exchanged between two PCMCIA cards (until the UA packet : I should receive then a UIH packet...).
Has anyone ever faced this problem ?
I don't think this is a hardware problem. Nevertheless, I am sure the things I send are right.
I wonder if my answer (UA packet) was not to late : I noticed it was really fast on PCMCIA cards. Is there any timer in this?
In advance, thanks a lot.
