Up until this point we have interfaced with the flight controller using a direct connection via USB cable. This is fine for adjusting parameters of the flight controller, but we have not been able to monitor the vehicle while it is in flight. In flight monitoring has not been necessary so far, but for GPS based flight modes, it is very beneficial to have quick and easy access to the flight controller. With this connection we can do things like view the aircraft's position on a map, or upload new way point missions remotely.

Adding a telemetry is easy, as they should come in pairs so communication out of the box will not be an issue Connect one radio to the USB port of your computer, and another to the “TELEM 1” port on the flight controller. Once this is completed, the process for connecting your ground control station is the same as if it were via direct connection. If multiple vehicles are in flight using telemetry radios, it is necessary to make sure they are paired correctly, via the radios ID number. TO check the ID number of your radios, open Mission Planner, and without connecting to your aircraft go to the Initial Setup menu, and under the Optional Hardware select “3DR Radio.” Press “Load Settings” to see what the current Net ID of each radio is. You can then switch to whichever ID you please and load the setting by pressing the “Copy Required Items to Remote” button.
