# BLE peripheral example
|
||||
|
||||
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||||
|
||||
This example creates GATT server and then starts advertising, waiting to be connected to a GATT client.
|
||||
|
||||
It uses ESP32's Bluetooth controller and NimBLE stack based BLE host.
|
||||
|
||||
This example aims at understanding GATT database configuration, advertisement and SMP related NimBLE APIs.
|
||||
|
||||
It also demonstrates security features of NimBLE stack. SMP parameters like I/O capabilities of device, Bonding flag, MITM protection flag and Secure Connection only mode etc., can be configured through menuconfig options.
|
||||
|
||||
For RPA feature (currently Host based privacy feature is supported), use API `ble_hs_pvcy_rpa_config` to enable/disable host based privacy, `own_addr_type` needs to be set to `BLE_ADDR_RANDOM` to use this feature. Please include `ble_hs_pvcy.h` while using this API. As `ble_hs_pvcy_rpa_config` configures host privacy and sets address in controller, it is necessary to call this API after host-controller are synced (e.g. in `bleprph_on_sync` callback).
|
||||
|
||||
To test this demo, any BLE scanner app can be used.
|
||||
|
||||
A Python based utility `bleprph_test.py` is also provided (which will run as a BLE GATT Client) and can be used to test this example.
|
||||
|
||||
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
|
||||
|
||||
### Configure the project
|
||||
|
||||
```
|
||||
idf.py menuconfig
|
||||
```
|
||||
|
||||
* Select I/O capabilities of device from 'Example Configuration > I/O Capability', default is 'Just_works'.
|
||||
|
||||
* Enable/Disable other security related parameters 'Bonding, MITM option, secure connection(SM SC)' from 'Example Configuration'.
|
||||
|
||||
### 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
|
||||
|
||||
There is this console output when bleprph is connected and characteristic is read:

* NVS support is not yet integrated to bonding. So, for now, bonding is not persistent across reboot.
