772 +If the sensor receives correctly, the data is returned along the original path.
773 +Note: If you forget the original address of the sensor, you can use the broadcast address 0XFE instead. When using 0XFE, the host can only connect to one slave, and the return address is still the original address, which can be used as a method of address query.
