Dear List I am trying to decode SDCCH. but I am not able to do it properly. Here is part of burst_ind app_ccch.c code. if (rv == 0) { uint8_t chan_type, chan_ts, chan_ss; uint8_t gsmtap_chan_type; struct osmo_phsap_prim pp; /* Send to GSMTAP */ rsl_dec_chan_nr(bi->chan_nr, &chan_type, &chan_ss, &chan_ts); gsmtap_chan_type = chantype_rsl2gsmtap( chan_type, bi->flags & BI_FLG_SACCH ? 0x40 : 0x00 ); gsmtap_send(gsmtap_inst, arfcn, chan_ts, gsmtap_chan_type, chan_ss, ntohl(bi->frame_nr), bi->rx_level, bi->snr, l2, sizeof(l2) ); here l2 is 23 byte. I need to remove send it to lapdm to decode it further then will pass it to RR. Please help me in using Lapdm for decoding :) -- Akib Sayyed Matrix-Shell akibsayyed(a)gmail.com akibsayyed(a)matrixshell.com Mob:- +91-966-514-2243
