XENSIV™ 60GHz BGT60TR13C Radar System on Module MCU4
Set and get configuration
4 Set and get configuration
The user can set or get the configuration of the radar under the “Parameter” tab. The following items are
currently available:
the firmware version in MCU.
[0.66 to 10.2]
Get or set the maximum detection distance for presence detection.
The setting would be stored in Flash; default is 1.00 m.
Get or set the sensitivity level presence detection; higher
means more sensitivity to small movements. Changing the sensitivity
would change the macro and micro threshold values. “Max”
sensitivity is a special setting that will extend the observation time to
10 s, which means the response of changing from presence to
absence will have a delay of 10 s. The setting would be stored in
Flash; default is high.
Note: The user is recommended to use a “max” sensitivity setting for
optimal performance at angles and for use cases such as a person
sitting on a chair behind a table.
Enable/disable active output command of presence or absence event
change. The setting would be stored in Flash; default is on.
Get current presence detection result
on or off. Default is on. When set to off,
radar chip power would also be set to off.
Enable or disable the RF continuous wave mode for FCC test.
Presence detection needs to be off before enabling this mode.
Disable: Disable RFCW mode.
Low: Set RFCW output at 61.02 GHz.
Mid: Set RFCW output at 61.25 GHz.
High: Set RFCW output at 61.48 GHz.
Low TX off: Set RFCW test at 61.02 GHz with TX off.
Mid TX off: Set RFCW test at 61.25 GHz with TX off.
High TX off: Set RFCW test at 61.48 GHz with TX off.
Perform tests related to the radar chip. Presence detection needs to
be off before enabling this mode. Self-test covers SPI checking and RF
test utilizes internal test hardware. Please run the self-test in an
environment where there is an empty space of 50 cm in front of the
radar.
Set the radar module to deep sleep mode. The module w
again when data is received at the UART RX pin. A preamble byte such
as 0x00 is needed to add in the next command so the command is
correctly received at the module (to compensate for wake-up delay
time).
Enable/disable active output command of calibration message. A
calibration message would output periodically when enabled. The
message would contain the activity level used to compare with the
macro/micro threshold value at that time. This mode is mainly used
for measuring the background noise of macro and micro detection, to
tune for an optimum threshold value for the environment.
