Hi everyone:
I wonder if someone can explain to me what the heck is LRRP and how do you use it. It looks like the MAP files for FMP, but nothing seems to happen. The Map files work as they should and show on the map whatever frequency I enter into DSD+. I have been wondering about what LRRP is and how to use it for months now, just never got around to posting it to ask. Any information you can give would be greatly appreciated. Thanks!

LRRP stands for Location Request Response Protocol.
You first must find a DMR system that is using LRRP, which will show up as location (LOCN) reports with GPS coords in DSDPlus).
If you find such a system, you would open LRRP.exe and the location data would be plotted on the map.

That's it in a nutshell.

Additionally, I have a couple of conventional DMR channels belonging to local school districts that broadcast LRRP data for their buses.

There is a NEXEDGE system here with subscribers broadcasting AVL data. When DSD+ sees an update, it gets displayed immediately in the LRRP program.

Thank you SlicerWizard:
I was wondering if you can post a screenschot of what the DSD+ event screen window is receiving when receiving LRRP data. I don't think I have ever known about it until now and I would like to recognize it the next time I see it. Thanks so much.

DMR LRRP and NXDN AVL:
Thanks again slicerwizard. That's looked very interesting to watch. I have found one frequency here that I
have seen LRRP in DSD+, but didn't know what it was at the time. I've been monitoring the freq for several
days and whatever it is, is very inactive. Maybe I'll get lucky and find something that I can test it out on. I will be looking for LRRP and LOCN lines in my logs from now on!

They are the data points.

Yellow = last update

Green = older update (don't know why there are several shades of green - old and very old?)

Circle = stationary

Wedge = moving

Wedge size = speed

Wedge orientation = direction
