3DR modems connected but won't do mavlink

Posted by Michael Walker on July 9, 2014 at 9:07am

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

But...

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.

Thoughts?
