With an ArduCopter setup, I have:
- a pair of Modems (hextronix ones -- i'm not sure if that is a problem or not)
- Updated the firmware
- Solid green lights
- Exact same settings on both on 433Mhz
- Default settings and latest firmware
- I have connected them both to a computer at the same time and linked one to the other and then used Putty to send characters -- so the radios work and are paired
When I connect them to Copter, Mavlink won't connect despite using the right com ports and baud rates. I have copied the settings from one to the other with MP.
