Oh i am sorry. I think i got it. osmobts-trx was not running. There was simply no configuration being distributed from layer2 to layer1. (as far as i understand it) That guide is quite useful but also quite lengthy :D http://openbsc.osmocom.org/trac/wiki/network_from_scratch
cheers, Christian

Now i wanted to communicate with a second phone and have tried setting up a BTS following this guide
http://openbsc.osmocom.org/trac/wiki/network_from_scratch (using a single phone)
My problem is that the phone doesnt transmit anything. Yes i have enabled the transmitter flag in the Makefile. ;) When i use osmocon to load the TRX into the phone and start the osmocom-transceiver i get this debug output from osmocon.
... Synchronize_TDMA =>FB @ FNR 26585 fn_offset=2002505 qbits=4924 LOST 1910! BTS MODE: 255 65535 {0,0,0,0,0,0,0,0} TX 0..7 RX 0..7
After taking a look at the code the values seem weird and they come from the transceiver function l1ctl_tx_bts_mode() like that. /host/layer23/src/transceiver/l1ctl.c:120
As a test i got the phone to transmit something by overwriting the values on the TRX side.
I havent gone further yet but wanted to ask if someone could maybe point me to an obvious mistake i did before i spend more hours on this issue. A hint as to how i enable the different logging settings would be great as well.
thanks, best regards, Christian
