Speedybee F405 Wing Telemetry Not Working

ArduCopter Copter 4.6
1

Hello all,

I am building a bicopter that uses a Speedybee F405 Wing as its flight control computer. I cannot get my telemetry units to cooperate with the board. I am using RFD 900+ Modems, and I know that the boards will talk to each other (I tested them on a CubePilot Orange and they worked fine). I’ve narrowed down the problem to the Speedybee itself, but I don’t know where to go from here. I checked the pinouts and adjusted the baud rates, but that didn’t help anything. Does anyone have any insight as to what to do from here? Any help would be appreciated.

Thanks,
Seth

Hi

Is the RFD modem powered by the FC itself ?
Check that you didnt configure the modem for too high power, maybe your FC cannot supply enough current

The RFD modem is getting power directly from the servo rail, so I wouldn’t think it’d be an issue of power.
