diag-parser

Build Status

Parse the Qualcomm DIAG format and convert 2G, 3G and 4G radio messages to Osmocom GSMTAP for analysis in wireshark and other utilities.

Building and Using

Building on GNU/Linux with autoconf, automake, make, gcc, libtalloc, libtool already installed.

$ ./build/build_local.sh
# Use -i to configure logging using DIAG and write to net+file
$ ./diag_import -g A.B.C.D -p local_file.pcap -i /dev/ttyUSB0
# Use an existing diag file
$ ./diag_import -g A.B.C.D -p local_file.pcap trace.bin

Dependencies

The system is using libosmocore of Osmocom. The build/build_loca.sh will git clone and configure it.

Usage

-h: Display the help output

-g A.B.C.D: Send GSMTAP frames to A.B.C.D:4729

-p file.pcap: Write GSMTAP to PCAP file

-i: Initialize DIAG interface on the device

Wireshark has GSMTAP display support and will automatically display and decode GSM/3G for these frames.

Devices

Development is done using Quectel UC20 and Quectel EC20 modems inside a PCengine APU2 system.
