Unable to Connect to WIFI

ESPHome
1

Hello!

I am struggling to install ESPHOME onto a NodeMCU esp32.

Originally I believed the error to be coming from my wifi password, as it contained special characters which may have caused issues with the string parsing, so I changed that, but am still getting stuck in the same place. It compiles and then the following error happens after it tries to connect to wifi:

Serial output error:

Here is my configuration:

ESPHome v2021.11.4

I’m new to ESP32 and home-assistant, and debugging these errors. I’m unfarmiliar with how to parse these logs, I am interested in learning how/using a tool to do it.

Can anyone help provide me with a direction on what I should try next next? A link to a debugger script/tool would be useful too.

Thank you

Edit:
Things I’ve tried without success:

  • Swapped boards (I have a spare of the same board)

  • Erasing flash memory via esptool.py github download and running erase_flash on dev/ttyUSB0. I’m not sure that it has worked as I get this:

[16:38:35][C][ota:452]: There have been 5 suspected unsuccessful boot attempts.

Is there another way to clean out the board, as now I suspect this is the issue?

What version of esphome are you running?

3

Version: ESPHome v2021.11.4

If you have a link to your device, please post it.
There are so many variations of “NodeMCU” like devices those days…

Try with the generic ESP32 config and see what result you get:

esphome:
  name: test

esp32:
  board: esp32dev
  framework:
    type: arduino

or this:

esphome:
  name: esp32
  platform: ESP32
  board: esp32doit-devkit-v1

Which works for all my cheap ESP32 clones.

The issue is may be the S in esp-32S.

ESP-IDF framework¶

This is an alternative base framework for ESP32 chips, and recommended for variants of the ESP32 like ESP32S2, ESP32S3, ESP32C3 and single-core ESP32 chips.

Thank you @zoogara - I updated ESP Home to v2021.12.3, and used the configuration you recommended, then performed a hard reset by holding down the Boot button (GPIO0) and the EN button (EN (CHIP_PU)) at the same time, power cycled, and we’re online!
