I’m about to start a project where four Arduinos will be talking to each other every other minute and also to a central server ~100 times a second and haven’t really found a satisfactory way to handle the communication. Had been hoping to use ZeroMQ as I have some experience with that but it looks like there are no Arduino compatible libraries available.

However, this looks just like the thing I’ve been looking for. Serial communication and TCP and CRC checking!

You could also use ROS Arduino serial library -

You could also use MQTT, which is a lightweight messaging protocol intended for embedded devices.
