To add NFC to bangle js same as in puck

Hi,

i came to know that banglejs doesnt have nfc chip along with nrf832 module.
can it possible to add that external chip or antenna same as in case of puckjs

I'm afraid the NFC pins of the nRF52 on Bangle.js are used for other things, so you can't add NFC in the same way as on Puck.js.

However you could still add an NFC sticker - there was a discussion about it a few months ago: http://forum.espruino.com/conversations/­353075

thanks gordon for reply. 3 questions i have?
any GPIO's exposed on bangle js to add nfc antenna or chip?
I see SOC nRF52832 has support of NFC, can i activate NFC radio or emulate it without antenna?
where is the NFC antenna in the puckjs is it along with nrf SOC or where it embedded in puckjs?

No - they're literally all used: https://www.espruino.com/Bangle.js+Techn­ical

Also only D9/10 can be used for NFC, and they are definitely in use as I said above.

No - doing so would disable D9/D10 which would stop the LCD working

It's buried inside the PCB, right around the edge.
