Pixhawk cube And Jetson Nano Connection

Hello there,

I have Pixhawk Cube and Jetson Nano, I want to communicate with each other, but I could not communicate with each other. When I connect the Jetson Nano to the Telem2 pin of the Pixhawk Cube, it does not work and the GPS does not work. But when I don’t connect the Jetson Nano, the GPS light works. Can you help me ?
