Hi,
I used Arduino IDE.
I have a ESP-32S and when I’am trying to do the example ” Wifiscan” I have this message :
Arduino : 1.8.8 (Windows 7), Carte : “ESP32 Dev Module, Disabled, Default, 240MHz (WiFi/BT), QIO, 80MHz, 4MB (32Mb), 921600, None”
Le croquis utilise 650862 octets (49%) de l’espace de stockage de programmes. Le maximum est de 1310720 octets.
Les variables globales utilisent 37040 octets (11%) de mémoire dynamique, ce qui laisse 290640 octets pour les variables locales. Le maximum est de 327680 octets.

Hello Pierre, did you hold-down the FLASH/BOOT button while uploading your Arduino sketch? Please read the “4. A fatal error occurred: “Failed to connect to ESP32: Timed out… Connecting…”” section: https://rntlab.com/esp32-troubleshooting-guide/
