# BLE Mesh example
|
|
|
|
This example is part of upstream mynewt-nimble implementation and not maintained by Espressif.
|
|
|
|
IDF maintains ESP-BLE-MESH as the official Mesh solution. Please refer to ESP-BLE-MESH guide at:
|
|
https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/esp-ble-mesh/ble-mesh-index.html
|
|
|
|
(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](https://mynewt.apache.org/latest/network/mesh/index.html#bluetooth-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:
|
|
|
|
```bash
|
|
idf.py set-target <chip_name>
|
|
```
|
|
|
|
### Configure the project
|
|
|
|
Open the project configuration menu:
|
|
|
|
```bash
|
|
idf.py menuconfig
|
|
```
|
|
|
|
* Select `Enable BLE mesh functionality` under `Component 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.
|
|
|
|
## Example Output
