[Bangle2] Firmware at v19 but DFU stuck on v12

Initially I started out with a v10 DFU.
1. I updated the DFU to v12 on https://banglejs.com/apps/
2. I updated the firmware to v19 using nRF Connect (failed on the web)
Now I've got a v19 firmware with a v12 DFU.

I tried nRF Firmware Upgrade, Web, nRF Connect. Still v12 DFU.
Am I wrong to assume, I should be on v19?

Cheers

yes (you are wrong :-), DFU bootloader is separate component that is rarely changed and is not needed to update so often. It is also a bit more risky to update it, so no need to do it just to see higher number.

The firmware update app still offers v12 DFU as the latest so it is OK.

That explains a lot :) Thanks!

Yes, just to add to @fanoush that I don't often publish new DFU versions in the firmware updater specifically because if nothing has changed in it I don't really want people risking updates if the only thing that's changing is the version number :)

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
