doodle labs and joystick setup

@Eric-Katzfey could you please help me out here

@Jetson-Nano Let's try to walk through this and see where it is going wrong. Please provide answers to all of the following questions. Go to the joystick tab in QGC and press the button on the joystick that you want to use for turtle mode. Which number lights up when you press the button? Next, go to the MAVLink console and provide the output of these commands: ver all, listener manual_control_setpoint, param show VOXL_ESC_MODE, param show VOXL_ESC_T_ON, and param show COM_RC_IN_MODE. If VOXL_ESC_T_ON is not set to the number of the button you just discovered on the joystick tab then change it to the value you want. For example, by default VOXL_ESC_T_ON is set to 9. If you want to use button 10 instead then do param set VOXL_ESC_T_ON 10. If you had to change that parameter then reboot and verify that it is now set correctly. You should see the aux1 value in manual_control_setpoint change from 0.0 to 1.0 when you press the button that you have chosen. Can you verify that you are seeing that?

@Jetson-Nano If all that seems to be working then press the turtle button and arm (with drone right side up, not upside down) and verify that with turtle mode enabled the propellers are spinning in the opposite direction and the drone won't lift off. Of course, you must be extremely careful when running this test!!! Make sure that the drone is in a location where it cannot cause damage or injure someone if it goes out of control. It would be best to completely remove the propellers and just verify that the motors are spinning in the opposite direction of normal flight.

I followed the steps you suggested, i am attaching the Screenshots. I tried what you suggested the result is still the same, I am not able to arm the system. I tried with various options for VOXL_ESC_MODE, still the same.

I clicked the assigned button here, AUX 1 values are changing but only when i keep the voxl_ESC_MODE to UART passthorugh

@Jetson-Nano Here are the steps I am using for testing. Here are my VOXL_ESC parameters:

My VOXL_ESC_BAUD is set non-standard because I am using an ESC simulator. I have flight mode set to altitude mode. If I check the ESC commands I see no output:

Then I arm and check ESC commands and see values:

Then I disarm, press button 9, arm, move both sticks around and see these ESC commands:

Notice that most motors are 0 except for 1 or 2 and are of opposite sign than normal. In this case pitch was centered and roll was full right. Hope this helps.

Thank you for reverting back, I will check these out and get back to you. Also I will flash the FC once more and see if I have any luck.
I would like to know which is the version of PX4 you are using.

@Jetson-Nano I was using v1.14.0-8.106.1
