Hello everybody Not sure if someone has pointed it out already, but I'm getting stuck following the gprs decode tutorial [...] - 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... # patch -p1 < ~/gprs_sniffer/gprs_multi.patch can't find file to patch at input line 5 [...] Can someone drive me to the right direction? Thanks! Dario

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.
