I am trying to decode gsm control channel using usrp+gnuradio+airprobe.
I get the cfile using ./gsm_scan.py -re -d164 -c643 -pe . But when i try
to decode this cfile, I get a file which is not properly decoded. I am
uploading part of the decoded file as I am not sure what the error is.
Instead when I decode wget
cfile, I get proper decoded file and output on wireshark.
Another small doubt is that when I run the ./gsm_scan.py -re -d164 -c643
-pe command, I do not get the sync initially, but when I change the
frequency up or down and come back to the c643 I get sync.
