Readers of this forum may recall the post I sent in some time ago seeking advice about Cell / nRF24 communication between a remote sensor set and a base station.
previous posting : guuooo-tech-iot-ga6 / nRF24L01 comms
Anyway I subscribe to another thread about ESP32 and received these links, showing that Espressif have recognised the need and addressed the issue :
ESP-NOW is a fast "connectionless" communication protocol developed by Espressif that features short packet transmission and allows multiple boards to exchange data without using Wi-Fi
RandomNerds : ESP-NOW getting started
Learn how to establish a two-way communication between two ESP32 boards using ESP-NOW communication protocol. As an example, two ESP32 boards will exchange sensor readings (with a range in open field up to 220 meters ~ 722 feet)
RandomNerds : ESP-NOW link 2
This appears to be an elegant solution to my project (just as I am getting back into the middle of it!) though the range made be just at the limit of what I want to do.....
