Common Configuration Commands.

Configuring Detection Range:setRange、getRange
4.1.1
Describe:
 The 5.8GHz microwave radar module supports a maximum detection distance of up to 11m.
 The 5.8GHz microwave radar module has a transition zone of 1m, which means that if the maximum
detection distance is set to 3 meters, it may detect targets between 3 and 4 meters. At around 4
meters, significant movement may be necessary for detection, and it's possible that targets may not
be detected at this distance (depending on the target's characteristics). However, beyond 4 meters,
such as at 4.5 meters, no targets will be detected. Therefore, users need to pay special attention
to this feature when configuring the maximum distance parameter to accurately define the detection
area.
Note: The 5.8GHz microwave radar module is not designed specifically for distance measurement and the current version has
not been calibrated for distance, so the distance can only be used for reference and may involve some deviation or error.
