I have been playing with my LD2410C, and had the same lack of serial communication, until setting the baud rate to 9600.
Check that your LD2410 device is operational with the HLKRadar tool - this operates via bluetooth
Test the serial connection on using either:
(1) https://github.com/vjsyong/LD2410
with the baud rate to 9600
In the `example.py` file:Output of `example.py, on Rpi5B`:
(2) Alternative python code: https://github.com/csRon/HLK-LD2450, again 9600 baud:

I am not sure whether the serial 9600 baud requirement is an issue with my sensor.(py312)[Rpi5NVMe:.+10C/HLK-LD2410B]$ python plot_targets.py
