Connecting 3 Jetson Nanos for Agri-Robot IoT Applications

We are currently working on an agri-robot project which currently uses three Jetson Nano to run three different functions (i.e., navigation, pest detection, and spray application). We intend to capture the data from those three Jetson Nano using another Jetson Nano board. The fourth Jetson Nano board will then upload the data into the cloud for IoT applications. Our roadblock now, is how to connect the Jetson Nanos together or to create a communication between two Jetson Nano boards.
Any kind of help would be greatly appreciated.

I don’t have answer, you may google it or find if any more sharing projects at Latest Jetson & Embedded Systems/Jetson Projects topics - NVIDIA Developer Forums to see if can gain some ideas.

Thank you but unfortunately, we cannot find that much resources from google and from the shared projects which we can use as a reference.
If ever, is there a way on how to make a communication between two Jetson Nanos so that can transmit and receive data from each other?

Publisher/Subscriber type frameworks such as ROS or MQTT are preferred by engineers because they are easy to implement for communication.

MQTT is very simple and it is easy to execute hello world.
ROS is a very powerful framework, but very quirky. It requires a lot of professional study.
