Import gprsdecode utility from SRLabs
This change introduces a modified version of gprsdecode utility, which is intended to decode the GPRS burst captures and forward decoded packets to the GSMTAP sink. The following modifications were made: - use shared libosmocoding library for GSM 05.03 coding; - use optget for command line options parsing; - use a single application select loop; - use GNU automake as the build system; - add regression tests (GNU autotest); - clean up and comment the code; - add license headers; The code is based on work of SRLabs: https://srlabs.de/ git://git.srlabs.de/gprsdecode.git Related: OS#1672 Change-Id: I12234d37c66b83b8abd60f7511fa1d7837db1856

GPRS decoder for OsmocomBB
|

|
||||
Usage: ./gprsdecode <burstfile>
|
||||
|
||||
The burstfile should contain samples, captured using burst_ind branch.
|
||||
An example of decoded output as well as few sample capture files could be found in tests/
|
||||
|
||||
Based on the version from git://git.srlabs.de/gprsdecode.git
