2. Configure over Wi-Fi

After flashing, the board starts its own access point esp32-e-ink-AP (password remoteqth). Connect to it — the setup page opens automatically (captive portal). If it does not, open http://192.168.4.1.

The only required field is your Wi-Fi SSID + password (optionally a Device ID). Press Save and the board reboots and joins your network. Full guide on GitHub.

Flashes: bootloader, partition table, boot_app0, firmware, SPIFFS filesystem. For manual flashing use esp32-e-ink-20260707-full.bin at offset 0x0 with esptool.py.
