So, I had finally gotten GUI to connect wirelessly to drone, but when I go to VMC Control, and try to “open all servos” nothing happens, and if I try to change LEDs to red, green, or blue they don’t even turn on.

Do you have a USB-A to Micro-USB connection from your Jetson to your PCC?

Yes I do, weird thing is that it works sometimes, and then it sometimes does not work…

My team had this exact same issue. Check the micro USB cable between the Jetson → PCC as it likely is loose. Try replacing the Micro USB connection cable.
