  1. Open the ESP-IDF web flash tool
  2. Connect the ESP32 via USB and put it in flash mode (hold BOOT, press EN/RESET, release BOOT)
  3. Click Connect and select the serial port
  4. Set address to 0x0
  5. Choose the full.bin for your board and click Program — flashing takes about 30 seconds

After the first serial flash, all subsequent updates can be done wirelessly via the device web UI (OTA tab → select the firmware.bin for your board).

First-time WiFi setup

After flashing, the device starts a setup access point when no WiFi credentials are configured or the network is unreachable.
