============
opensuse linux 10.1
bluez 2.24
hcidump 1.29
============
Problem:
My program's logic:
(1) have 1 thread named sensor to discover other bluetooth devices
(2) have at most 7 threads named workers, each worker will push a file to
the scheduled device.
(3) have 1 thread to scheduler the found deivces to the workers.
the problem is,
Each worker,
first to search the obex service in its target device. (use sdp_connect
to create a connection, in fact a l2cap connect)
if obex service found, then push the file by OPENOBEX. (use
Bt_TransportConnect to create a connection)
For the coccurent workers, the l2cap connections are created coccurently.
So there is some error occurs such like errcode 103, errorcode 113,
errcode 16,timeout
In the former discusstion in the maillist, sem_t could be used to sync the
call of connect
so, I use a sem_t conn_sem to sync, but I found that no improvement.
Who can give me a nice suggestion?

the baseband page can't be done simultaneously. Run "hcidump -X -V" to
see what error will show up.
