What is the status of this project?

[ajsrikanthaj]

I want to use HLK-LD2461 in my smart home and I want to know the current status of this project like, is it in a working state or not.
I am developer by profession and I shall contribute if I can.
My sensor is getting delivered in a week, waiting to try out.

[Chreece]

You are free to continue this work.
I have stoped developing on this project since I read some tests on this sensor that didn't quite have good results.
If you need any documentation please inform me and I can also help you with testing. I'm only a hobbist and don't have excellent developing skills...

[ajsrikanthaj]

Thank you for the response. I would like to continue this project and need some info from you.
What is currently working and what is not?
Links to the resouces you used to develop this.
A brief code walkthrough if possible.

[Chreece]

The official manuals + serial protocol exist here: https://drive.google.com/drive/folders/14_KgZpL4Th2LTRuq_W0X_ePjHu_Z6lcS
Unfortunately it's long ago since I used the code and can't tell any more what works and what doesn't.
I just tried to adapt the code to: https://github.com/uncle-yura/esphome-ld2450

[Chreece]

hey :)
how's your project doing? need any help?

[ajsrikanthaj]

I am waiting for my sensor to get delivered. I will test once I get the device and update you on this.
Thank you.

[Chreece]

it should compile now but i don't think you will get any results

[ajsrikanthaj]

Still getting same compilation issue

[ajsrikanthaj]

What do you think it will not get any results?

[Chreece]

Sorry, I'm a hobby programmer and not a professional developer like you. I don't get any compiler errors but the sensors don't get any values.
Can't help you much with the code, but I can help you testing your code if you need help
