I followed the Serial/UART tutorial here and everything worked fine; I can send data over USB using the Serial interface. I then based myself off of the getAccelerometerData.m file to test passing data back and forth between the Holybro Telemetry Radios while both are connected to my laptop; I've attached the .m file here. I've also attached the Simulink model.
My challenge is sending the same data, but between the Pixhawk 4 and my laptop (where one telemetry radio is plugged into the pixhawk and the other is plugged into my laptop); even though the LED indicator on the radios indicate they're communicating (which they do when I open QGroundControl), I can't get any kind of data to transfer over them. I've tried using both the TELEM1 and UART & I2C B ports on the Pixhawk (and changed the corresponding Simulink Model parameters to communicate over /dev/ttyS1 or /dev/tttyS4. I've verified that I selected both the appropriate port on my laptop, and on the Pixhawk, and tried different combinations, to no avail. In short:
Does anyone know how to allow data transfer over the Telemetry Radios between the Pixhawk and my laptop?
I'm running Windows 10 1809, Ubuntu 16.04 WSL, Pixhawk 4 with latest firmware (v1.9.0, I think), MATLAB R2018b, and the Telemetry Radios have been flashed using QGroundControl with the latest firmware.
Edit: This is literally something that is recommended to try in the Simulink documentation here: Configure the PX4 Serial Transmit and Receive model to exchange data over other serial ports of the Pixhawk Series controller.
So how do I actually do that?
