Finally
i get the solution. I had seen that a guy is waiting 1.5 s after boot to activate Wifi and his comment is for 5V line stabilisation.
I have inserted a time.sleep(5) before wlan.active(True)

IT'S WORK

From my point of view it's not related to Thonny as with IDE Arduino ESP32 i get Wifi freeze

With micropython i am using Thonny connected to ESP32 board with USB cable

I have tested wifi connexion with esp32 Arduino IDE Using Wifi library #include <WiFi.h> void setup() { WiFi.begin("myNetwork","myPassword"); serial.print(WiFi.status()); } void loop() Serial.print("."); } I can see my ESP32 board connected to myNetwork, but ESP32 never reaches the print instruction...

I have tested STA with

import network
wlan= network.WLAN(network.STA_IF)
wlan.active(True)

Same error message
So in AP and STA mode wlan.active(True) instruction do crash

Tomorrow i will test Wifi using C code to see if DEVKIT V1 board Wifi works

Good evening With this simple code with ESP32 DEVKIT V1 board ( 2 units tested) with esp32-20210902-v1.17.bin import network wlan= network.WLAN(network.AP_IF) wlan.config(essid='MyESP', password='12345678') wlan.active(True) In console the following message appears : Connection lost(EOF) Use Stop/Re...

I had seen that SIM800L circuit requires a lot of current during initialization.

Is your battery delivering enough current ?
