This example shows how to use the APIs to connect in secure manner with peer device and use encryption for data exchange.
To test this example, you can run [ble50_security_client_demo](../ble50_security_client), which starts scanning, connects to and starts encryption with `ble50_sec_gattc_demo` automatically.
Please, check this [tutorial](tutorial/ble50_security_server_Example_Walkthrough.md) for more information about this example.
## 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>
```
There are some important points for this demo:
1.`esp_ble_gap_set_security_param` should be used to set the security parameters in the initial stage;
2.`esp_ble_set_encryption` should be used to start encryption with peer device. If the peer device initiates the encryption,
`esp_ble_gap_security_rsp` should be used to send security response to the peer device when `ESP_GAP_BLE_SEC_REQ_EVT` is received.
3.The `ble50_sec_gattc_demo` will receive a `ESP_GAP_BLE_AUTH_CMPL_EVT` once the encryption procedure has completed.
