Hey, osmocom has changed a bit, layer23 has been replaced by ccch_scan, the easiest way would be to open the patch file and patch those files manually, most of the changes will fit if you look for those rows, as I said, patch app_ccch_scan instead of layer23 and you should be fine. lukash On Thu, Oct 20, 2011 at 10:17 AM, Dario Lombardo <dario.lombardo@libero.it>wrote:

- Prepare OsmocomBB's burst_ind branch
cd ~/gprs_sniffer/osmocom-bb
git checkout origin/sylvain/burst_ind git checkout d1cb8ea9b784c7acbafbb2fdcedbdf4655c2f6f5
At this point I get
fatal: reference is not a tree: d1cb8ea9b784c7acbafbb2fdcedbdf4655c2f6f5
Next step fails too... pretty obvious...

another question: who can I use more than 2 phones? mo1: ./host/osmocon/osmocon -m c123xor -p /dev/ttyUSB0 ./target/firmware/board/compal_e88/layer1.compalram.bin mo2: ./host/osmocon/osmocon -m c123xor -p /dev/ttyUSB1 ./target/firmware/board/compal_e88/layer1.compalram.bin If if use only one mobile, ttyUSB0 / ttyUSB1 is working, but if I started both at the same time, only one mobile is working. Same with 2 different firmwares. How can I set up more phones to get the whole frame / up- and downlink. -- View this message in context: http://baseband-devel.722152.n3.nabble.com/GPRS-decode-tutorial-tp3437051p34...

1) You must launch everything twice, including launching ccch_scan (or layer23 for older version). 2) Look in the command line option of osmocon and ccch_scan, you will find an option to specify the l2 socket. Each pair of software needs a different socket. 3) There is a software in the gprs git to then 'combine' both output in a single file
thank you for your fast reply. Now both mobiles are working. For the downlink-frame should I use 2 different firmwares with different schedulers? -- View this message in context: http://baseband-devel.722152.n3.nabble.com/GPRS-decode-tutorial-tp3437051p34...
