I'm not familiar with usb so have a noob question probably.
What populates result.data
? Like do we write into that thing, are first 8 bits which represent the length something we write or something standard?
Asking because we could potentially avoid the whole for
loop here for string parsing and use TextDecoder instead.
Even if we just cut off the length
and pass in the rest text decoder should be able to handle that.

Sorry to request this, but I feel like since it's a new file we should aim to get rid of at least the most obvious problems with the old code.
Something to start with:
- Removing commented out blocks of code in webdfu.
- Removing
self = this
pattern, it's not relevant anymore with classes and arrow functions.
There is defo more but these would at least put us up for better coding conventions in new code.
EDIT: refactored whole function and now it works. |

@nerdCopter how did you test? Works locally (yarn dev). Have not checked on Netlify. This code needs to run in secure context. Screencast.from.14-05-24.18.18.48.webm |

Okay, i get the DFU via your described process. it does not erase/flash, but the DFU is there. |

@nerdCopter should work now. Removed flash protection as it does not work on F4 or F7 |
|
@nerdCopter this is to be expected as PortHandler did all the hard work but currently is disabled for PWA. |
Testing using
yarn dev
On Ubuntu Firefox does not support these web APIs, as snap install of Chromium does not work either.
Need to install package like:
