Device control turns off the APP camera and exits the photo preview function

Note: After receiving this command, the app must call the following event to reply to the camera preview shutdown result when the preview is successfully or unsuccessfully turned off

Flutter example:

/// Reply to the camera preview pause result
replyDeviceStopCameraPreviewRequest(
evtBase: _VBusEvtBase.base_app_set,
evtType: _VBusEvtType.app_ble_to_app_stop_camera_preview)

/// Reply to the camera preview pause result
libManager.send(evt: CmdEvtType.replyDeviceStopCameraPreviewRequest, json: jsonEncode(json));

JSON fields sent by the App:

Example:

{
"error_code":0x00
}
