NOTE
If you cannot be sure that the scan data can be processed at the same speed as it
is output by the device, you should only query the scan data individually. The scan
counter, telegram counter, and time stamp in the output of measured values can serve
as an indication that processing is too slow.

RSSI values
RSSI (Received Signal Strength Indicator) is the measure of the energy that the sen‐
sor receives. This value is determined for each measurement and has a logarithmic,
arbitrary unit. The RSSI values have a resolution of 8 bits with whole-number values
between 1 and 255, where 1 stands for the weakest signal and 254 for the strongest
signal (e.g. with one reflector). A value of 255 means “dazzled”. The value 0 (zero)
means that the received energy was too low to produce a valid RSSI value. A valid
distance measurement has at least an RSSI of 1.
