From 35a8a614f7f32fe574152545f35d6e9779b35f6a Mon Sep 17 00:00:00 2001 From: Paulus Schoutsen Date: Sat, 4 Jul 2026 09:30:42 -0400 Subject: [PATCH] Consolidate duplicated vendored JS into shared /js/ jszip.min.js existed twice (byte-identical); the toolbox and the nrf_web_tools demo page now both load /js/jszip.min.js. The web-serial polyfill existed twice under different names, and only toolbox/serial.js had the unhandled-rejection / byte-reordering / port-close fixes (146f4c0). That fixed copy is now /js/web-serial-polyfill.js and the stale nrf_web_tools/web-serial-polyfill.js is gone, so the demo page gets the fixes too. nrf_web_tools.js existed twice, and the toolbox shipped the older revision without the multi-part DFU reconnect flow, so multi-image NRF52840 packages dead-ended there after part 1. The newer copy is now /js/nrf_web_tools.js and both pages load it. Both copies export the same NrfWebTools API and the zip path resolves against the page URL, so the move is drop-in. Script-injection src values and their querySelector guards updated in both pages to the new absolute paths.

This tool will help you update the firmware on your nRF52 device using nRF Web Tool.

-
-

How it works:

-
    -
  1. Click "Start Update" below
    2. -
  2. Select your device twice: -
      -
    • First time: for reset (1200 baud) - device will enter DFU mode
      • -
    • Second time: for flashing (115200 baud) - firmware will be installed
      • -
    -
    3. -
  3. Wait for the update to complete
    4. -
-

Note: The browser will prompt you to select your device twice. This is normal and required for the update process.
