hi, i am no shure if i already sent this mail, but i can't find it anywhere. this fixes the delay of audio caused by stalling of the openbsc process. the use of 'usleep(100000)' for slowing down transmission to nanoBTS is replaced by the tx-delay timer. i did this on bs11 code, so i did it the same way. it actually queues frames for transmission not nanoBTS. on transmission a timer is started and when this timer expires, the next frame in the queue is transmitted (timer restarted) until the queue is empty. regards andreas
