Radar setup

There is a command called cansend, that belongs to can-utils, used for sending configuration messages to the radar. Here are some messages proposed, but other messages can be sent (watch the manual ARS40X_Technical_Documentation_V 1.8_18.10.2017 inside documentation folder).

Installation of can-utils

sudo apt-get install can-utils
candump can0 // Watch the raw data received once the peak CAN bus is installed and connected to Radar

Configuration messages to choose between cluster detection or object detection

cansend can0 200#F8000000089C0000 // Objects detection with all extended properties
cansend can0 200#F8000000109C0000 // Clusters detection with all extended properties

Configuration messages for applying different filters.

cansend can0 202#8C0000012C // Maximum distance of objects detected 30 meters
cansend can0 202#AE06800FFF // Minimum value of object RCS -10 dBm2
cansend can0 202#C600030007 // Minimum value of objects probability of existence 75%

Other option to configure the radar is to modify the values of configuration_vars.h inside the header folder of socketcan brige. Please remember that is necessary to build the package again in order to save the values chosen in the configuration header file.
