9.2.4 Tracking with buffering – Start (sNf)
Triggers continuous measurements of the distance with internal buffering in the device (buffer for one measurement). The rate of
measurements is defined with the sampling time. If the sampling time is set to zero, the measurements are executed as fast as possible
(Measuring speed depends on target conditions). The last measurement can be read out from the module with the command sNq. The
measurements are continued until the 'sNc' command is issued.

Parameters

9.2.5 Read out - Tracking with buffering(sNq)

After starting "tracking with buffering" with the command sNf, the latest measurement can be read out from the module with the
command sNq. This command does not work if the tracking with buffering is not started.
Command
Return successful
Return error
Parameters

9.2.6 STOP/CLEAR command (sNc)

Stops the current execution and resets the status LEDs as well as the digital outputs.
Command
Return successful
Return error
Parameters

9.2.7 Signal measurement (sNm)

Signal measurement can be done continuously or with a single measurement. The signal strength is returned as a relative number in the
typical range of 0 to 40 millions.
The value for the signal strength is just an approximate value, it differs from device to device and also depends on environment conditions.
