I just got the 3DR radio today and am trying to get it working. Following the instructions I get to the part where it says to click on the load settings tab in the mission planner and this error comes up every time.See attached screen shot.
I have a solid green light on both, On the air unit the red light is flashing. ON the ground unit the red light does not come on other than very faint when I first plug into the USB port.
Please let me know if there is something I can try. I am lost.
please download the latest mission planner 1.1.90
Works perfect!!! Thank you very much for the fast reply. The new mission planner looks great. Cant wait to spend some time on it.
