Hello great program, Here in Australia orux is used alot for 4wd maps. Alot of these 4wd's have uhf radios installed in them for comunication. There is a certain radio GME XRS that can send location data over uhf to another user when ever they talk into the headset. It would be great to be able to see the location of another user on the map whenever they talk through the radio. I believe it is done through AT commands with a bluetooth serial connection from the GME XRS radio to the phone and app (orux in this case). The at command set can be found here - https://www.gme.net.au/app/uploads/XRS-Connect-AT-Command-Reference.pdf and information about the radio and its location service can be found here https://www.gme.net.au/au/getxrs/ thankyou very much.
