Special Case: Mode Command
This "set"-command allows to put the sensor into a specific scan mode.
There are two currently available:
•
Mode 0: continuous scanning, the sensor scans its environment and
returns scan messages continuously. (No Ack)
•
Mode 1: single scan, the command triggers the sensor to scan only
once and return the corresponding scan message. (No Ack)
