Android NRF firmware update failing for puck.js

I attempted to update the firmware on my puck.js from 2.09 to 2.16 using the recommended nrf firmware update app for Android on my Samsung Galaxy s10+.

I'm able to select the puckjs v 2.16 zip file as well as connect to the puck ... but at the progress stage all 3 steps fail with a final error message saying the device does not support nrf5DFU.

I tried the same thing from my chromebook but running the DFU app on the chromebook will not connect to the puck.

Any help appreciated!

You need to switch puck.js to DFU mode first so it is visible as DfuTarg device. Typicaly it is done by holding button, rebooting device (E.reboot()) and quickly releasing button, check puck.js docs for more details.

As above, you're connecting to 'Puck.js abcd' not 'DfuTarg' - I imagine the green LED isn't lit up?

There's quite a thorough writeup on https://www.espruino.com/Firmware+Update#nrf52

Thanks! I'll read up ... but I think I just misunderstood the sequence on getting the puck in DFU mode. Will check this today and post results.

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:
![](https://www.google.co.uk/images/srpr/logo4w.png)
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.
