Return value

- ESP_OK: Success - ESP_GATT_INVALID_HANDLE: Invalid GATT `start_handle`, `end_handle` - ESP_GATT_INVALID_PDU: NULL pointer to `count` - ESP_FAIL: Failure due to other reasons

Notes

1. This API does not trigger any event. 2. `start_handle` must be greater than 0, and smaller than `end_handle` if the `type` is not `ESP_GATT_DB_DESCRIPTOR`.
