[bluetooth-dev] Whats the difference between btduser and btd (digianswer/axis)



Hello,

I'm using 20010108 stack together with Digianswer's
Bluetooth Software Suite.
(Axis stack running as server).

When running the btduser I succeed in connecting to the axis side
successfully
to for example the serial port profile.
But when running btd it will fail.


-> LTP : transmission
*(...) ... : reception (length) packet type.

Has anyone succeded this in kernel mode. Does it work as it should so?
Seems to me that the "only" difference is that in kernel mode
it somehow tries to send 2  ACL packets after setting the timer.
while in user mode it sends one does a do_cmd_backupup
sends another starts the timer (L1976).
receives two num_compl_packets

BTW it works when using only 1 acl packet.


Best Regards
Stefan Thomasson
