One ESP32/E220 (gateway) and two ESP32/E220 (Endpoints/Sensors)

[George]

I’m studying the forum tutorials about EBYTE modules (thanks Renzo for the tutorials).

How to configure One ESP32/E220 (gateway) to receive sensor readings from Two ESP32/E220 (endpoint) sent every 5 minutes?

Is it necessary to make some code to avoid collision of messages sent by the ESP32/E220 (endpoint) to the ESP32/E220 (gateway)?

The examples I’ve seen on the internet only show examples with expensive commercial gateways to accomplish this task.

Thank you so much

Hi George,
For E32, I develop a gateway with a graphical user interface that uses WebSocket (not MQTT).

EByte LoRa E32 gateway: manage via REST and WebSocket (esp8266, esp32) – 1
EByte LoRa E32 Web Manager: description, configure and demo (esp8266, esp32) – 2

You can add MQTT with a few codes, and if you have some patience, I will develop It for E22 and E220, but now I must finish the E220 library and documentation.

If you have some time to spend, we can collaborate for the E220 gateway, the conversion of the E32 version Is pretty fast, but the web interface to control it needs more time.

I think that spending more than 10$ on a gateway It’s a stupid thing :P.

Bye Renzo
