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:

idf.py set-target <chip_name>

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 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 (...) NimBLE_BLE_PERIODIC_ADV: BLE Host Task Started
I (...) NimBLE: Device Address:
I (...) NimBLE: xx:xx:xx:xx:xx:xx
I (...) NimBLE:

I (...) NimBLE: GAP procedure initiated: extended advertise; instance=0
I (...) NimBLE: instance 0 started (periodic)

I (...) main_task: Returned from app_main()

Note

• Periodic sync transfer is not implemented for now.
