I’ve been trying to set up the LD2410 sensor with a D1 Mini V4.0
But sadly enough without any positive results…
I already order an second LD2410 with the thought the first one would be malfunctioning.
Also tried a different min connector cable but also no success.
Only thing that I have not tried it is a different D1 Mini module…
Although both I can read you through bluetooth with the chinese app on my phone.
Here is a small read out of the logs regarding the sensor:
I’ve enabled the UART debbugging to see the data coming in but that seems not usable?
I also notice that sensor gets pretty warm/hot dont if any users experience this?
Hope you guys may have any tips

Alright I’ve got it working !
Apperently the physical RX/TX pins aren’t that good.
Luckly we have another option on the D1 board so I’ve moved over tx_pin: GPIO15 and rx_pin: GPIO13
That didnt work right away and that was because I was powering the board with USB from my laptop so that must have used something regarding the communcation which interrupted the UART
So now powering it just through a power source its working fine
Just a guess but, as USB also contains data cables which connect to the UART (probably). I would say they have either powered from just a USB wall plug or power only cable.
Mine are all powered from a USB cable but the wires are soldered to the power pads on the board. I do this because it takes up a lot less space.
I think the main reason for getting it to work from my side was switching from GPIO01 / GPIO03 to GPIO15/GPIO13
And after that I had some troubles becacuse I was powering the board through a USB connected to the laptop
And therefore there must have been some data interference on the UART bus
I tried to connect LD2410 with pins on it to d1 mini. At first it worked. I connected GPIO1 and GPIO3. But as I messed something up it stoped working and I’m unable to make it work with d1 mini. I tried GPIO13 and GPIO15 but nothing changed. Try to reverse tx and rx wires, the same. It doesn’t work. I changed the board to esp32 wroom and it’s working flawlessly for a few days now. I connected board to 3.3v and GPIO1 and GPIO3 pins on esp32. In my opinion there is probably problem with connection on d1 mini. This is the only thing that comes to my mind. For a price difference of 1.5 € its better to get esp32 board. I ordered a BH1750 light sensor and will connect it to the board. If this work it will be a pritty neat presence sensor.
This is my working code for esp32

Most likely cause, both for you and maybe others above too:
TX and RX stand for transmit and receive. When you connect them to another device, tying TX to TX and RX to RX won’t work, because both devices send on the same line, and both devices listen on the same line. Those need to be swapped. If one side transmits (TX) the other side must listen (RX) on both lines.
So: swap pin 1 and 3 and try again. It will probably work.
Another thing to note:
If you have an ESb32 device with a USB port, then the USB almost always also uses pin 1 and 3 for serial communication. So, while you flash over USB, don’t connect the LD2410 to the same pins (that is one of the reasons why another uart might be more convenient).
Once you flashed and discunnect USB from a PC (an adapter is fine, that won’t use the uart). Now you can connect to pins 1 and 3, and do firmware updates OTA.
And last but not least, if you post yaml, format it correctly, between three backticks:
Tnx for heads up, but I know that and probably do others. For me d1 mini just doesnt work,
But I found out better board.
esp32-c3-devkitm-1
is in my opinion is the best, at least for my small projects. There is a lot info online about this board, but what I like the the most is that this board is running on low temperature compared to esp32.
It runs on basically the same firmware and the same hardware attached to it nearly 50% cooler.
And this is great because it will harder cache fire than high temp running esp32.
I cannot look in your head to see what you know and I’m not trying to offend. I just read a lot of posts of people who had trouble getting the LD2410 to work, until they switched RX/TX.
If you are worried about temperatures then maybe you should know LD2410 will feel hot to the touch when operating. Hotter than an I ever experienced with all of my esp32’s, mini or otherwise.
Yeah I know, I tried it and it is hot. But speaking about the board I was really impressed with esp32-c3-devkitm-1. And it works better than a standard esp32 board.
I’m not offended, dont worry about it, just saying. If you done one upload using cables you will never ever forget to swap tx/rx.
Hi to all again at last the d1 mini works stable , looks like this chip have memory issues … or something else have no idea , sort the code more and works very stable now.
