ESP8266 not possible to connect to WiFi

petrklic16 · May 23, 2024, 7:56am

Hi,

i would like to ask you. I’ve bought this ESP module

and when i try connect to HA via ESPHome, after step “prepare for first use” everythink is ok, installation was completed, but after that when ESP will try to connect to Wifi, I’ve got “An error occurred. Improv Wi-Fi Serial not detected.”
I’ve tried it many times but still same.

I’ve checked serial monitor and there is log -

Do you know what is wrong?

Thank you so much.

Post your YAML code too.
I could be you have chosen a board type with too little memory.

petrklic16 · May 23, 2024, 8:20am

It’s without yaml. I’ve just click in HA to ESPHome -

and after that i’ve jsut click to Prepare for first use

Installation was completed and then i’ve got thsi message.

Interesting is that when i tried it first, it worked. I think i have to delete internal memory of ESP, bu i dont know how i can do it.

I have this ESP Universal e-Paper Driver Board with WiFi SoC ESP8266 onboard, supports various Waveshare SPI e-Paper raw panels

Upload a empty file to the esp and start again.

petrklic16 · May 23, 2024, 8:31am

how i can do it? :-/

Sandalman · May 23, 2024, 8:49am

Connect to the server/computer click “edit” delete the lines and click upload.

petrklic16 · May 23, 2024, 8:51am

ok i will try it. Thank you

There is a issue with esphome:

github.com/esphome/issues

ESPHome 2024.5.0 + D1 Mini + LD2410 = The connection dropped immediately after encrypted hello

opened 09:31AM - 15 May 24 UTC

### The problem The issue starts to happen after upgrading to ESPHome 2024.5.…0. My LD2410 presence sensors are working fine with version 2024.4.2. The firmware compilation log is attached: [logs_bedroom-presence-sensor_run.txt](https://github.com/esphome/issues/files/15319373/logs_bedroom-presence-sensor_run.txt) I will try to rollback now and see if i will be able to recover the sensors. ### Which version of ESPHome has the issue? 2024.5.0 ### What type of installation are you using? Home Assistant Add-on ### Which version of Home Assistant has the issue? 2024.5.3 ### What platform are you using?
