Esp32 c3 super mini + ld2410c Unable to read value

[ljeffyl]

I tried for about 4 days until I succeeded on one on the third day.
But after running for about 26 hours, I couldn’t read the data.
Other same hardware and software couldn’t read it either.
I got a bit crashed. I need help.
My English is not very good

I tried TX=RX RX=TX or TX=TX RX=RX but it doesn’t work
I also encountered a problem during this process. I was wondering if it is possible to replace the RX and TX interfaces through software without having to swap hardware? I don’t know if it is possible.

Hi
May be because of ESP board definition.
see this post:

Getting Esphome to Work With an Esp32-c3 Board

I have an Espressif esp32-c3-devkitm1. I wanted to add it to esphome running in Docker. I tried all sorts of different ways to get it recognized without success. I finally got it work by connecting it to the box running ubuntu and the Docker image. In the add device process there’s an option to use the host on which esphome is running. It didn’t work right off. I had to change the compose file to allow it to find the esp32-c3. This is my compose file: services: esphome: container_name: e…

Old thread but I thought I’d chime in. I am having success with the following UART settings.

uart:
  id: ld2410_uart
  tx_pin: GPIO0
  rx_pin: GPIO1
  baud_rate: 256000
  parity: NONE
  stop_bits: 1
