I do have a question about the pixhawk mini and Qgroundcontrol
I wan to calibrate the RC transmitter (Graupner mz-12) and the Receiver (Graupner hott, 2400) by means of Qgroundcontrol under ubuntu 16 over the Pixhawk mini.
I have connected ch6 from the graupner receiver to the RCIN on the pixhawk mini.
I have binded ch1 to ch 5 (transmitter and receiver), and set up to “ON” the RF transmit from ch1 to ch5 on the receiver. In other words, RF sett->rx = R06 (which means is binded) and RF->RF = ON. In every channel from 1-5 and channel 6 is set to “free”
Then on my Graupner mz-12 I went into the Telemetry->Settings & Data View menu, scroll to bottom where it says SUMD on ch6 and change to yes
When i click in the radio icon on QGroundcontrol
I always get "detected 0 radio channels. to operate px4 you need at least 5 channels
Good day,
Spektrum and DSM receivers must connect to a SPKT/DSM input of the pixhawk mini,
PPM-Sum and S.BUS receivers must connect directly to the RC ground, power and signal pins typically labeled RC or RCIN
PPM receivers that have an individual wire for each channel must connect to the RCIN channel via a PPM encoder like this one (PPM-Sum receivers use a single signal wire for all channels).

Which one of the three cases is my case? And, how can I solve it.
Would you mind explaining more according to my setup
I wan to calibrate the RC transmitter (Graupner mz-12) and the Receiver (Graupner hott, 2400) by means of Qgroundcontrol under ubuntu 16 over the Pixhawk mini.
I mean:
settings in the RC transmitter
which channel in the RC receiver
is there anything I need to set up in the QGroundcontrol
I have the same issue with mine. My setup is Pixhawk, Lemonrx plugged into Spektrum/PPM port. Receiver binds fine with my Spektrum DX6 by itself. When I try to bind through QGroundControl, bind fails in any of the three modes. With the rx bound, I get the message that 0 radio channels are detected. What do I do next?
From my experience, I’ve found it best to bind the satellite Rx first with a regular receiver first and test to make sure all outputs are working there. From that point, transfer the satellite Rx to the Pixhawk then do your RC calibration in QGC.
There is a massive hole in my knowledge. I am very new to the drone/quad world. All of my previous RC experience has been in sailboats, and they all use ‘standard’ configuration rx & servos. I have no experience with satellite Rxs. I think I understand that the satellite is bound through another rx with a PPM port. Do both have to be on board, or do I run with the satellite only on the quad after binding? Is there a tutorial somewhere I can read on this? Thanks for putting up with this overly-long post.
Mount the satellite rx as far as possible from other electrical/electronic components.In my case, I used a 3ft extension and mounted it on the vertical fin.
Depending on the airframe you chose during your initial setup, you can assign up to two RC channels to AUX1 and AUX2 ports of the Pixhawk. For example, you can use these channels control a camera gimbal.
In your first case, after bind and unplug the satellite rx from the reveiver and plug into the DSM port of the Pixhawk, what should you do with the receiver?
After I plug the satellite rx into the DSM/SBUS RC port in Pixhawk 4, I can use QGoundControl to set the rx into bind mode again, but still I cannot calibrate the transmitter(no channel found, and no signal show on the screen of transmitter).
You don’t need the receiver anymore since your Satellite Rx is now your receiver.
Once you bind the satellite Rx with the main receiver, then plug the Satellite Rx to the FC, you don’t need to bind again since your Tx is already bound to it. You should be able to just go to the Radio tab and perform the calibration.
Maybe it lost its bind with the Tx when you tried to bind again in QGC. Rebind it using the main receiver and then just plugin to FC. Make sure the Tx is on before powering the FC. Once it’s powered up (via USB), confirm that the Satellite Rx LED is solid (not blinking) to indicated it’s bound/connected to the Tx. Calibration should work at that point. If the Satellite Rx is blinking, check to make sure the wiring is correct in reference to the pins of the FC.
By the way, you didn’t say what Tx you’re using; is it a Spektrum or Taranis? If it’s Taranis, I believe you have to modify and extend the range. On my QX7, I’ve had to set it up with 22.5ms and -400u.
I bought the Holybro QAV250 kit with the Pixhawk 4 mini. It also came with the R-XSR reciever. I hooked the reciever up to the RC IN port and binded it with the a FrSky X-Lite successfully. When I enter QGroundcontrol, I get the same message as mentioned above. PLEASE advise!
