diag-parser

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.
