RAP and SNF documentation


I’m working on a project to integrate RAP14 reports (*GPSR = 0x14) from GX4x0 devices to our existing GIS systems.

I have been able to receive and parse location data (*GPSR = 0xE1) and device id using NMEA over UDP. But when SNF is enabled or when GPSR is changed (0x11 thru 0x14) the datagrams are no longer plaintext.

Are the packets being sent in a binary format? Is there a library or spec that I can refer to parse these packets? I’m looking for any kind of documentation on the format for Event Reports.

Thank you!
