I am using an 3DR RadioV2 for my telemetry connection on a plane build that connects to an APM2.6. I can properly connect the APM to my computer and upgrade the firmware and do calibrations and such in Mission Planner. However, when I disconnect the APM and reinstall it back into the plane and hook all the wires back up and then attempt to connect via telemetry I get an error that says, " No Heartbeat Packets Received." I have the baud rate at 57600 and I am on the correct COM port. The light on the radio has two led lights on when I try to connect: One solid green and one flashing red (on both radios). I am able to “load settings” in the 3DR Radio tab under “Optional Hardware” and both the local and remote radios populate with values that are identical.
Does this mean a faulty radio? Or is this a firmware/settings issue?

Any help would be appreciated and thanks in advance!
