    help
        If this config item is set, raw binary data will be used to generate advertising & scan response data.
        This option uses the esp_ble_gap_config_adv_data_raw() and esp_ble_gap_config_scan_rsp_data_raw() functions.

        If this config item is unset, advertising & scan response data is provided via a higher-level esp_ble_adv_data_t structure.
        The lower layer will generate the BLE packets. This option has higher overhead at runtime.
