Hi,
I seem to have problems with the gsmframecoder. If I compare a cleartext burst
with a decrypted burst (they are the same) with the output from this tool,
there
are some differences. Can anyone please explain why this might be? Bug perhaps?
Example:
Where c is the cleartext burst, e is the encoded output from gsmframecoder and
d
is the decrypted burst.
