Hi,

I am wondering how simple or difficult to flash BangleJs firmware (current beta stage) on another watch.

I saw one of my friend is wearing the same watch that he purchased couple of months back. I discuss him about the hackable watch and he is excited to see on his watch. :).

So I might have a early testing device before I will have mine in March 2020.

Hi! There's a bit of a discussion on http://forum.espruino.com/conversations/341425/

Basically you can unscrew the watch, peel back the LCD, then solder on wires for SWD and program a hex file using an SWD programmer like the nRF52DK.

It's not something I can spend much time helping you with, but someone else might write up the process?

Ok, I hope opening the watch is not an option for me. Can it be done Bluetooth over the air by nrfConnect app? Since the watch seems exactly same?

It's described in the link above.

Short answer is: if you're not happy opening the watch, the hoops you have to jump through to program wirelessly are going to be too painful as well.

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.
