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.
