I just got my APM2 and 3DR radios. I got the radios setup, and have the APM talking to the Ground Station. Telemetry and gps is being sent to the GCS and all seems well until I tried to "play around" with the terminal mode.
The terminal shows a bunch of scrolling garble. I was once able to get into AT command mode once using +++ in the 3DRConfig tool, at which point the garble stopped, but I cannot consistently enter command mode.
Is this garble normal? If not, what is causing it? Why can't I consistently enter command mode?
Thanks in advance.
