FrSky SBUS to CPPM stops working after upgrade to 3.2.1

Posted by David Jackson on March 28, 2015 at 10:27pm

I have tried this 3 time now and all ways the same results. I have been runing 3.1.5 FW on my Pixhawk for some time. I have a Futaba R7003SB RX with a FrSky SBUS to CPPM to connect to the Pixhawk. When I upgrade to 3.2.1 my RX stops talking to the Pixhawk. If I down grade back to 3.1.5 everythings works again. I have tried taking the FrSky SBUS to CPPM out and using a streight connections form RX to Pixhawk while running 3.2.1 with no joy.

Any help to get me up and running on 3.21

    With the later versions of firmware you don’t need the converter. Just connect the R7003SB direct to the RC in port of the Pixhawk and you will have all 14 channels.

    I fly mainly airplanes and all the airplane versions have supported direst Sbus input up to 14 channels since last summer. I assume that the multirotor firmware has the save code Sbus code as the airplane firmware.

     

    Make sure that you are using Sbus and not Sbus2.
