I'm quite new in the world of drones and would like some help for a project I have.
I have an Iris+ with a Pixhawk and my project require to send the GPS coordinate to another on board board.
I firstly thought to use one of the free UART port on the Pixhawk but that require to change the code and I don't want to alter anything because I need a robust system.
So I thought that I can receive the GPS coordinate on Mission Planner for example so, without any modification, the port TELEM necessarily send this info (among others things).
So here are my questions:
- What is the protocol used to communicate between the port TELEM and the 3DR Radio module?
- There are 2 TELEM ports. I understood that one is for the radio (TELEM 2) and the other is for OSD: so what are the differences between these two ports?
Thank you very much for your help.
