Can anyone point me to info on how to best add an NFC antenna to the MDBT42Q Breakout board?

Were you originally planning to make the (tx,rx) version of that call available more broadly? (which would be handy, by the way). I'm just wondering how to interpret that note in the capSense API ref saying:
"Note: This is only available in NRF52 devices (like Puck.js, Pixl.js and MDBT42Q)"...

It seems that Puck.capSense() is the way to go. By the way, how do you access Puck.capSense(tx,rx) on MDBT42Q?
The documentation says "Note: This is only available in NRF52 devices (like Puck.js, Pixl.js and MDBT42Q)", but when I try to call Puck.capSense on an MDBT42Q breakout, the IDE complains that "Puck" is not defined...

As far as moving the UART over to a different pin and getting better results, I'm wondering if it's related to an issue I was having where the console was taking over to the USART1 pins on the Puck when I disconnected from the IDE. Basically the same as this troubleshooting post:
http://www.espruino.com/Troubleshooting#console
Except instead of calling USB.setConsole(), for me the fix was to call:
Bluetooth.setConsole(true);I did this both on the init event, and at the top of my code, and it addressed the issues I was having where it looked like console activity was appearing on my serial connection when I connected and disconnected from bluetooth. This allowed me to interact with a UART device on the tx,rx lines...
Gordon or others, please correct me if I'm wrong here, but if this is correct, it might be worth it to add bluetooth related info to that troubleshooting page.

The update button in chrome://extensions/ did the trick. Now on 0.70.3. Thanks!
Interesting note: This version of the chrome app now says its name is "Default bleoifhkdalbjfbobjackfdifdneehpo.app", whereas the version I had before said "Espruino Web IDE.app". Not a big deal...

@Gordon, I have a bunch of the same devices and so grabbed the board info from the one I switched over to after the other stopped working.
Rebooted IDE. I'm still on 0.69.1 though... Maybe I should reinstall the Chrome app...
Low Battery! I should have thought of that. Maybe low battery also caused the file loading glitch in the first place?... With charged LiPo, the board is working well again. These boards are awesome. Everytime I think I've bricked one, it comes back to life. I've never experienced this level of robustness on other platforms...
Thanks!
Cool thanks. I was thinking of trying to use this antenna:

In the PDF you linked, it shows two capacitors (C19 and C21), one for each wire. I can't find what capacitance is needed. Do you know if I even need C19 and C21 when using an antenna like what I linked above?
Thanks for all of your helpful responses, Robin.
