Im working on a project where I will be using multiple Arduino (pro mini)'s which emit sensordata through LoRa.
The problem I am currently facing is, when I have multiple sensors, how do I know what data is coming from which Arduino (given they all have exactly the same source-code)?
- Does the arduino have a UID like some sort of MAC code?
- What could be a solution to give the Arduino a UID?
- Do you guys have any other solutions for my issue?
In order to answer #2, I could add a random number calculator to create, but this doesn't feel right to me.
