I am a new user of ESP32 and I need your help to understand this fantastic product

Sorry for my English language who isn't perfect and top of taht my 68 years aren't an advantage

I have some experience with industrial automation but you can considere that I am a newbies

I had already used Arduino Uno and my inteerest for ESP32 is the communication WiFi.

My firts question is about version of my ESP32 (normaly Expressif) =>
https://www.amazon.fr/dp/B0B4DPKJTQ?ref ... tails&th=1

I don't find if it's C2, C3 ... ?

Seconde question about the message of serial communication IDE Arduino :

14:26:43.567 ->
14:26:43.567 -> rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
14:26:43.567 -> configsip: 0, SPIWP:0xee
14:26:43.567 -> clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
14:26:43.567 -> mode:DIO, clock div:1
14:26:43.567 -> load:0x3fff0030,len:1344
14:26:43.567 -> load:0x40078000,len:13964
14:26:43.567 -> load:0x40080400,len:3600
14:26:43.717 -> entry 0x400805f0
14:26:43.843 -> E (179) psram: PSRAM ID read error: 0xffffffff
14:26:46.076 -> Connecting to WiFi
14:26:46.076 -> ....
14:26:50.078 -> WiFi connecté
14:26:50.078 -> 192.168.1.2 : 192.168.1.198

What's this read error ?

I hope your understanding and your help.

No worries, your English is better than my French

That board has a (clone of an) ESP-Wroom-32 on board, which contains the 'classic' ESP32.

ESP32 chips can have external PSRAM attached, which enables you to use more memory than the 500'ish K of internal RAM. Your module does not have that, and the read error is the Arduino environment trying to probe that chip. You can ignore it.

Thank a lot for your help but I need your help beacause when I try to load the following program inside my esp32

Code: Select all

esphome:
  name: esphome-web-e36494
  friendly_name: ESPHome Web e36494

esp32:
  board: esp32dev
  framework:
    type: arduino

# Enable logging
logger:

# Enable Home Assistant API
api:
  encryption:
    key: "souR3/tpme3dh3z4Dg5hsQy476J1kxf+U0jCPpXLg6Y="

ota:


wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Esphome-Web-E36494"
    password: "mg4kfyu9qmtC"

captive_portal:

web_server :
  port: 80

  # Example configuration entry
dallas:
  - pin: GPIO14

# Individual sensors
sensor:
  - platform: dallas
    address: 0x1C0000031EDD2A28
    name: "Temperature Piscine"

I get the following message :

Do you have an idea about this problem ?
