# BLE Multi Adv Example
|
||
|
|
|
||
|
|
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||
|
|
|
||
|
|
This example support legacy as well as extended advertisement for all phy. For multi advertising, random addresses are generated for each instance.
|
||
|
|
|
||
|
|
It starts 4 types of advertising:
|
||
|
|
* Non connectable extended
|
||
|
|
* Connectable extended
|
||
|
|
* Scannable legacy
|
||
|
|
* Legacy withe specified duration(5 sec)
|
||
|
|
|
||
|
|
## 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:
|
||
|
|
```
|
||
|
|
idf.py menuconfig
|
||
|
|
```
|
||
|
|
|
||
|
|
To configure number of advertising instances:
|
||
|
|
|
||
|
|
* Component config → Bluetooth → NimBLE Options → Enable BLE 5 feature → Maximum number of extended advertising instances
|
||
|
|
|
||
|
|
### Hardware Required
|
||
|
|
|
||
|
|
* A development board with ESP32-C3 SoC,ESP32-S3/ESP32-H4/ESP32-C2 SoC and BLE5.0 supported chips (e.g., ESP32-C3-DevKitC, etc.)
|
||
|
|
* A USB cable for Power supply and programming
|
||
|
|
|
||
|
|
See [Development Boards](https://www.espressif.com/en/products/devkits) for more information about it.
|
||
|
|
|
||
|
|
### Build and Flash
|
||
|
|
|
||
|
|
Run `idf.py -p PORT flash monitor` to build, flash and monitor the project.
|
||
|
|
|
||
|
|
(To exit the serial monitor, type ``Ctrl-]``.)
|
||
|
|
|
||
|
|
See the [Getting Started Guide](https://idf.espressif.com/) for full steps to configure and use ESP-IDF to build projects.
