• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

When the gatt_security_client connects to a Bluetooth mouse, it will not trigger the secure pairing process, and it will automatically disconnect after about 110 seconds of connection.
the configure:

#define GATTC_TAG             "RAPOO 5.0MS"
#define REMOTE_SERVICE_UUID   ESP_GATT_UUID_HID_SVC
#define REMOTE_NOTIFY_UUID    ESP_GATT_UUID_HID_REPORT

@jjj19950710
thanks for report the issu,I will check.

[esp-zhp]

The API for initiating pairing is 'esp_ble_set_encryption,' which is not actively called in the 'gatt_security_client' example. You can modify the example to initiate pairing when ESP_GATTC_CONNECT_EVT occurs.

[jjj19950710]

Now the client can initiate pairing requests proactively.Thanks very much！
