Thanks for the quick response @Gordon! I have a couple of issues with the approach you suggest: security risk, and the web-connectivity requirement that it presents. Both of them are non-starters for the application. What I really need is OOB pairing using the NFC interface.
I'll be going to C code for the final implementation, but was hoping to use Espruino for the 25 prototypes I'm building. It didn't seem supported at this point, but I thought I'd ask. Put it in the 'enhancements' bucket and see if anyone else is interested in this support going forward?
Thanks again,
Bill
I'm afraid it's not something that is specifically tested/supported, but potentially you could create a custom NFC tag with http://www.espruino.com/Reference#l_NRF_nfcRaw
I'm not sure what multi-device support is like, but IMO a nice easy solution for NFC pairing would be to set Espruino up with a passcode: http://www.espruino.com/BLE+Security
And then set an NFC URL of
http://mywebsite?addr=bt:ad:dr:es:ss&passcode=123456
. I believe you can then hook that URL to an app (and set that page to redirect to the relevant app store) and can work from there?
