ESP BLE Mesh Node demo

This demo shows how BLE Mesh device can be set up as a node with the following features:

• One element
• Two SIG models
  • Configuration Server model: The role of this model is mainly to configure Provisioner device’s AppKey and set up its relay function, TTL size, subscription, etc.
  • OnOff Server model: This model implements the most basic function of turning the lights on and off.

The default purpose of this demo is to enable the advertising function with 20-ms non-connectable interval in BLE 5.0. You can disable this function through menuconfig: idf.py menuconfig --> Example Configuration --> This option facilitates sending with 20ms non-connectable interval...

For a better demonstration effect, an RGB LED can be soldered onto the ESP32-DevKitC board, by connecting their corresponding GPIO pins are GPIO_NUM_25, GPIO_NUM_26, GPIO_NUM_27. Then you need to select the following option in menuconfig: idf.py menuconfig --> Example Configuration --> Board selection for BLE Mesh --> ESP-WROOM-32

Please check the tutorial for more information about this example.
