# BLE Periodic Advertiser Example
|
|
|
|
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
|
|
|
This example starts periodic advertising with non resolvable private address.
|
|
|
|
It uses Bluetooth controller and NimBLE stack based BLE host.
|
|
|
|
This example aims at understanding periodic advertisement and related NimBLE APIs.
|
|
|
|
|
|
To test this demo, any BLE Periodic Sync app can be used.
|
|
|
|
|
|
Note :
|
|
|
|
* Make sure to run `python -m pip install --user -r $IDF_PATH/requirements.txt -r $IDF_PATH/tools/ble/requirements.txt` to install the dependency packages needed.
|
|
* Currently this Python utility is only supported on Linux (BLE communication is via BLuez + DBus).
|
|
|
|
## 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
|
|
```
|
|
|
|
In the `Example Configuration` menu:
|
|
|
|
* Select I/O capabilities of device from `Example Configuration --> I/O Capability`, default is `Just_works`.
|
|
|
|
### 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.
|
|
|
|
## Example Output
|
|
|
|
There is this console output when periodic_adv is started:
|
|
|
|
```
|
|
I (313) BTDM_INIT: BT controller compile version [2ee0168]
|
|
I (313) phy_init: phy_version 912,d001756,Jun 2 2022,16:28:07
|
|
I (353) system_api: Base MAC address is not set
|
|
I (353) system_api: read default base MAC address from EFUSE
|
|
I (353) BTDM_INIT: Bluetooth MAC: 84:f7:03:08:14:8e
|
|
|
|
I (363) NimBLE_BLE_PERIODIC_ADV: BLE Host Task Started
|
|
I (373) NimBLE: Device Address:
|
|
I (373) NimBLE: d0:42:3a:95:84:05
|
|
I (373) NimBLE:
|
|
|
|
I (383) NimBLE: instance 1 started (periodic)
|
|
```
|
|
|
|
## Note
|
|
* Periodic sync transfer is not implemented for now.
|
|
|
