By now you should have a good understanding of what the ESP32 is all about, and you must be eager to get hands-on with it. Git Repo link;)

I totally understand :-).

Let’s proceed with the next level, where I’ll show you how to set up the ESP32-IDF MESH Core on 6, yeah, six ESP32 Heltec V2 board, linked together in an auto-healing network.

JUST CHECK IT OUT:

Code’s Description

This program automatically chooses what node becomes root.
TO MAKE IT WORKS, We include the OLED library and set up all the links at
Directory C:\msys32\home\USER_PROFILE\esp\esp-idf\components;
To test disconnect one of the roots and in approximately 30 seconds a new root will be chosen. Return the node and you will see it associated with the new root. Nice & cool experiment!
Test with at least three ESP32 boards.
Enjoy /

Commands:

$ make menuconfig -> Set your project port, location, etc
$ make erase_flash -> To erase the flash; before taking the final two-digit MAC Address reported here ( as NODE_NAME)
$ make flash -j5 monitor -> Flash the ESP32 and run the Serial Monitor at the end :)
