    EDIT:
    Sun 2019.12.01
    Solution suggested in post #13 does indeed work


    Was in the process of attempting to resolve an issue for another forum post and needed to
    flash to current version.

    Didn't want to hijack the following as I'm not flashing a Puck, but this may be related as it appears still unresolved. (three weeks now without update)

    Puck.js failed to update firmware; can't hard reset now

    fr #7 http://forum.espruino.com/comments/14936620/

    Still get the stuck uploading green bar, but an additional error using the native app.

    Entering bootloader mode releasing button after one second and view red LED is illuminated


    First attempt using WebIDE native app   v0.70.06
    Note that the device was found blue and then connected green

    TypeError: failed to execute 'requestDevice' on 'Bluetooth' required member filters is undefined.


    Needed to close IDE, unpair device, then 'Add a Device' then pair then relaunch IDE. That worked great
    until I tried the Chrome version. Then device becomes locked and unusable.



    Second attempt using Chrome Version 77.0.3865.120 (Official Build) (64-bit)

    Device is not able to be paired at this point. It doesn't even appear as recognizable in the 'Add a Device' BT settings section.

    Went to provide console output for native WebIDE app, but as device is now not recognized, get the 'No ports found' error when attempting to connect.

Web Bluetooth available, but Windows Web Bluetooth is broken in <68 - not using it



    Tried the five second hard reset, but still not seen

    Found this for STM32

    https://www.espruino.com/Serial+Bootloader

    Are there instructions on how to flash NRF52 using the UART?
