DFU32 guides users through installing or updating its firmware on an ESP32 board, then lets them stage an nRF52 repeater image over USB.

Landing page captured for the 2026-11-11 issue.

For: Operators installing DFU32 on ESP32 repeater boards
Worth noticing: Staged nRF52 packages are not labelled by board, so the page cannot confirm they match the repeater.

Field notes

The installer distinguishes a first install from reconnecting to a device already running DFU32: an existing device can report its board, while a new install needs the user to choose one. Custom builds come from a board-specific CI artifact, and the page explains that erasing removes saved WiFi, the API token, and the configured target. Its troubleshooting also gives manual boot/reset sequences for boards without auto-reset.
