Issue 24GHz mmWave Sensor - Fall Detection Module

Hello, I develop Fall Detection Module with seed XIAO RP2040. The Fall Detection Module connected to pins D7-Rx, D6-Tx in XIAO RP2040. But I didn’t receive raw data right from Module when the man fell. The Module didn’t terminate the human body position. Or I get data that the man fell after 1 minute. How can I get the right information from 24GHz mmWave Sensor - Fall Detection Module?
