3DR v2 Radios not connecting

Posted by Andros on July 21, 2015 at 3:05am

Hi there,

I've a problem with my new APM 2.6 and 3DR radios, they don't connect. The strange thing is that the radio on the quadcopter shows a solid green light (connected), wile the radio at the ground station is blinking green, so it doesn't seem to be connected. I've tried to change the NedID on both radios with no success. Baudrate is set to 57600 on both the APM and MissionPlaner. When I try to connect Mission Planer to the APM via radio, I get the "No Heartbeat Packets Received" message after 30 seconds.

Anyone has an idea? I've already tried to update to the master branch firmware of SiK but it still won't connect. I've attached my settings.

    Thanks guys, I think I've missed to tick Op Resend, it's working now!

    your "Op Resend" is not the same at both ends.

    Set same values for both radios (and if you're not limited by local regulations - set Tx power for 20, frequency range as wide as possible: 414-454, # of channels 20 or 30, duty cycle 100).

    Change NET ID for something different than default "25".
