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>
Configure the project
Open the project configuration menu:
idf.py menuconfig
In the Example Configuration
menu:
- Select I/O capabilities of device from
Example Configuration --> I/O Capability
, default isJust_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 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.
