This updates the minimal supported version of CMake to 3.16, which in turn enables us to use more CMake features and have a cleaner build system. This is the version that provides most new features and also the one we use in our latest docker image for CI. |

BLE Mesh example
(See the README.md file in the upper level 'examples' directory for more information about examples.)
This example implements Bluetooth Mesh node that supports On/Off and Level models. It has suport for both Advertising Bearer and GATT Bearer.
For more information on NimBLE MESH, please visit NimBLE_MESH.
It uses ESP32's Bluetooth controller and NimBLE stack based BLE host. This example can be starting step to get basic understanding on how to build BLE MESH node. To test this demo, any BLE mesh provisioner app can be used.
How to Use Example
Before project configuration and build, be sure to set the correct chip target using:
idf.py set-target <chip_name>
Configure the project
Open the project configuration menu:
idf.py menuconfig
- Select
Enable BLE mesh functionalityunderComponent config --> Bluetooth --> Enable NimBLE host stack.
Build and Flash
Build the project and flash it to the board, then run monitor tool to view serial output:
idf.py -p PORT flash monitor
(To exit the serial monitor, type Ctrl-].)
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.

There is this console output on successful BLE provisioning:
