problem on registering osmocombb SDR PHY setup to my virtual bts
I want to implement osmocombb SDR PHY project on USRP N210 in Dragon OS. for this purpose i setup Yate BTS with Blade RF in ARFCN 1. i test this bts by making call with two phone in this network. then i ran grgsm_scanner by USRP N210 and the log is >> Found CCCH arfcn: 1 Dont capture immediate assignments, skip extract SDCCH/8 info and scan...
