NFC add-on
#1
Has somebody an idea if it would be possible to solder-in some support for NFC?
(e.g.: so the watch could communicate with continuous glycaemia monitors like this, for which there is already opensource code available)

Unfortunately the pins required for NFC are being used for other things.

Yep that's correct, the conflicting pins are P0.09 and P0.10.

For Mynewt OS we have configured the two pins as GPIO pins instead of NFC pins...

That's because the pins are used by the display and touch controllers according to http://files.pine64.org/doc/PineTime/Pin...rev1.0.pdf

P0.09 / NFC1: LCD_DET (OUT)

P0.10 / NFC2: TP_RESET (OUT)

FYI NFC1 and NFC2 pins are for connecting the NFC antenna, see https://infocenter.nordicsemi.com/pdf/nR...S_v1.0.pdf
