Inter-device Communication

Hi everyone, I have a system with two distinct parts - the leader and the follower, both parts initially run on raspberry pi 4 model B, however, for AI capabilities the follower currently uses NVIDIA Jetson Orin Developer Kit. For a standalone project, the Jetson Orin works fine on the follower system. However, the next phase requires both systems to communicate, that is, the leader issues motion commands, which should be received and acted on by the follower.

My Question: How can I make the Raspberry Pi and Jetson Orin communicate together.

Thank you.
