Have a project that involves around 80 arduino-based puzzles and I’d like them to talk to one central control board - not sending much data, just status updates back and forth, so only a couple of bytes every few seconds per puzzle.
What’s the best way to do this? I have looked at NRF24L01 but was interested to know if anyone’s done anything similar/what you would try/other options. Distance is probably 10-20 metres across a large room at worst. Mainly looking for something with decent reliability, have never had great results with ESP32.
