      @Eric-Katzfey Thanks Eric! It definitely sort of works. Two things I note as I modified: 1.) The topic streaming rate appears to be double what you set using the '-r' argument in the 'mavlink stream' command. Also, 2.) I was hoping to get RC_CHANNELS and interestingly, that particular topic isn't showing up at QGC. HIGHRES_IMU, ATTITUDE, ATTITUDE_QUATERNION, ATTITUDE_TARGET, LOCAL_POSITION_NED, and ODOMETRY all stream back (at double rate). RC_CHANNELS has nothing...

        @JoeC Okay, interesting, I'll have to look into that.

          @JoeC The RC_CHANNELS message relies on the input_rc topic. Are you sure that that is being generated? Can you see it being logged in log files? Can you see it with px4-listener input_rc -n 1 when PX4 is running?

            @JoeC @Eric-Katzfey following. I'm using the VOXL 2 flight deck, Spektrum receiver, and Spektrum DXs transmitter. They are bound and I'm getting MAVLink messages in QGC, but no RC channels. PX4 is not publishing RC messages. Any feedback is appreciated!

            voxl2:/$ px4-listener input_rc
            never published

              @Taylor-Presley How are you starting px4? Is it being started via systemd service or are you starting it from the command line? Are you using the voxl-px4 script or calling px4 directly? You need to make sure that the script is trying to start the spektrum_rc driver otherwise it will produce no output. Can you verify that the spektrum_rc driver is in fact starting and not some other RC driver?

                @Eric-Katzfey I've tried both, below is the output after I disable px4 and then start it using voxl-px4. It does appear to try and start spektrum_rc and then returns the errors "Open failed on 8" and "dsm init failed." I also get "px4io read failed," is it possible they are related? Thanks in advance for your help!

                  @Eric-Katzfey Hi Eric and @Taylor-Presley you might find this helpful as well, I just had a chance to setup the Spektrum bind cable and a Spektrum receiver/xmitter. I AM now indeed getting RC_CHANNELS so I think my situation was because I didn't have the RC transmitter on the last time I was testing.

                  @Taylor-Presley I note in your posted photo, most services are not running; on mine that is working at the moment, I've got camera-server, cpu-monitor, imu-server, mavlink-server, portal, px4-imu-server, and vision-px4 all running. One thing you can try as well is to ensure you ran 'voxl-configure-mpa -p --family sentinel' and see if your setup starts working.

                    @JoeC I did try that because I figured I may have screwed something up during HITL testing, but input_rc is still not publishing, sensor_gps is not published, and px4io is still failing to read. I'm open to trying anything that may work, all comments appreciated!

                      @Taylor-Presley px4io will fail to read if you do not have a px4io board attached to VOXL2.

                        @Eric-Katzfey You can see in the script that if it fails to detect the px4io board (as you saw) then it will attempt to start the Spektum RC driver instead. However, your output shows that it fails to initialize uart 8. That doesn't look right.

                          @Eric-Katzfey Sounds like you have 2 issues here that are not related to the original post. Can you create 2 new forum posts for the Spektrum issue and the GPS issue? Then we can try to solve those independently. Thanks!

                            @Eric-Katzfey Thanks Eric, for future readers, I've created a new post at Voxl 2 Spektrum RC Issue.
