Telemetry radios won't stay connected

I plug in the air module and then the ground module, everything connects fine and I get steady blue lights. I connect Mission Planner, set the correct COM port and baud rate, and select Connect, and everything connects fine. After 3-4 minutes, the two modules disconnect, and both go to blinking blue status. The only way to get them to reconnect, is to disconnect power to quad and reconnect.

The really odd part is that if I don’t launch Mission Planner, the two modules will stay connected with no issue (steady blue lights on both). It’s only when I launch MP that things go wrong.

Any ideas?


There is no blue LEDs on 3Dr radio, so this may be between you and whoever made them
