Hi, when I use wireshark I see mostly "GSMTAP header ARFCN(525),Downlink TS0,channel BCCH0, which probably is normal since the phones do not register or see the network.Manual search is done with phones after removing and reinserting batteries. Shouldn't there be seen sip invite messages also.?Sipauthserve starts normally as well as smqueue.
When watching the 29c3 video,after finishing configuring transceiver file, before launching openbts, it looks like a command related to an ARFCN is given from inside the directory where the transceiver is residing, which command is that?
