How does a Raspberry Pi talk to an ESP8266?

In this project, I will explain what the MQTT protocol is and how it is used to communicate between devices.Then, as a practical demonstration, I will demonstrate how to setup a client and brocker system, where an ESP8266 module as well as RPi talk to each other or send message when a button is pushed. 1. Raspberry Pi 3 2. NodeMCU 3. LED 4. Button

Is there a way to communicate between ESP8266 modules?

UPDATE – If you need to need to make ESP modules talk each other but in totally different networks here is a new method to communicate between ESP8266 modules using Blynk Bridge. If you are a hobbyist / geek you definitely need to give ESP8266 a chance before trowing your money on high end monitoring systems.

When to send RTC readings to ESP8266?

If the closest AP middleman was not available the workers ESP were programmed to keep up to 10 readings in the internal ESP826 RTC memory during the DEEP_SLEEP, and send them whenever the AP gets back.

Can a 5km field be covered by ESP8266?

Yes, 5km, its a huge area, but it can easily be covered if you have imagination. How he did it? So this farmer spliced his 5km field in 4 area parts, and in each part has build a sub-network of 9 ESP8266 s.
