I am trying to connect Pixhawk 6X to Jerson Orin Nano. I am facing many issues.
I am not able to communicate Pixhawk to Jetson.
I am using QGround Control for Pixhawk.
I set all the parameters to Pixhawk. I am using TELM2, but not able to communicate.
Please someone suggest some answer.
Hi @Smalkhed, welcome to the forum 
I have moved your comment to its own post, because it was not relevant to the original topic you posted it in. I have also reformatted it to use normal text casing, to make it more readable and not feel like you’re shouting.
You have provided very limited information about your system, including what software/firmware you’re running on the Jetson Nano and the Pixhawk, and how you’ve tried to connect and configure things.
I’d suggest you start by searching the forum for setups similar to yours, and if that doesn’t help you to resolve your issue then please provide more context about your setup, how it’s connected, and what you’re expecting to happen that is not occurring.
