Command 
Name 
R/W 
Value 
OR 
Raw ADC Output On 
Write 
I and Q output buffers from the ADC will be 
sent. Data output will alternate between the I 
and then Q buffer. Or turns off raw ADC 
reporting. It’s not recommended to use OF 
with UART, especially at low baud rates. 
OL 
LED Control 
Write 
Turn the LEDs on (OL) or off (Ol). Turning off 
the LED’s can save approximately 10mA of 
current consumption. 
OM 
Magnitude Report 
Write 
Turn on reporting of the magnitude associated 
with the speed. The magnitude is a measure 
of the size, distance, and reflectivity of the 
object detected. Type Om to turn magnitude 
off. When turned on, magnitude information 
is reported before speed/range information. 
On 
Number of Reports 
Write 
Define how many reports to provide.  n is a 
number between 1 and 9. The number n 
applies to magnitude and speed reports. 
OT 
Time Report 
Write 
Turn the time report on. Time is reported as 
the seconds and milliseconds since the last 
reboot or power on.  For example, 137.429, 
3.6 is read as 137 seconds and 429 
milliseconds with a speed of 3.6 m/s. If 
magnitude is turned on, the data is provided 
as time, magnitude, speed. 
OU 
Units Report 
Write 
Report the current unit setting with each 
report. Default units is turned on. Use Ou to 
turn off. FMCW (-B) radar only. 
OV 
Range Report Order 
Write 
Changes the default order of the range 
reported to largest range value first to 
smallest as opposed to using largest signal 
magnitude. Use Ov to return to ordering by 
signal magnitude. Use O/ to report smallest 
range first to largest or turn back to largest 
first with O\. FMCW (-B, -C) radar only. 
BZ 
BL 
BS 
BC 
BT 
BV 
Blank Data Reporting 
Write 
If measured data does not meet filtering 
criteria, sensor will report out a character with 
every sampling interval. BZ will report zero 
value. BL will report blank lines. BS will report 
a space. BC will report with a comma. BT will 
report a timestamp. Use BV to turn off.
