NFC vCard

I don't have time to look into this properly right now, but as a sanity check does NRF.nfcURL("http://www.espruino.com") work fine for you, so you're sure you can read the Pixl normally?

It's just the VCARD code that is the issue?

Hello @Gordon, thank you for your response.

It's just the VCARD code that is the issue?

That is correct. nfcURL works without issue and can be read with multiple devices.

Ok, thanks. Does it work on other readers, for example Android?

@AntiCat did mention in http://forum.espruino.com/comments/14950929/ that you need to add that extra bit of code for iPhone. Did you give that one a try?

Yes, the NRF.nfcURL(...) was tested with and Android tablet and older Android phone as well.

Yes. But I will be the first to say it's not clear to me what order to perform this. If you combine the code samples, it does not work - but I do not expect it to either. It has to be something so simple that I am missing:

var data = new Uint8Array(16+872);
data.set("\x00\x00\xE1\x10\x6D\x00\x03\x00\xFE\x00", 0x0A);
var tag = require("NFCTag").create(data);

var vcard = require("NFCvCard").create("BEGIN:VCARD\n"+
                                     "VERSION:2.1\n"+
                                     "N:Doe;John;;Mr.\n"+
                                     "FN:John Doe\n"+
                                     "TEL;WORK;VOICE:(111) 555-1212\n"+
                                     "EMAIL:jondoe@example.com\n"+
                                     "END:VCARD\n");

Maybe @AntiCat could post the full code used to get it working so I can copy/paste it on my end and see similar results?

'I have provided what I thought was everything you asked for'

I re-read the posts starting with the #8 original inquiry. The requests are there in plain sight. It is quite possible @Tesseract-Developer that I over estimated the troubleshooting skill level using the environment within the WebIDE. Tackling a local module usually isn't a first step introduction. Maybe too much detail was missed going between posts, perhaps?

As Gordon pointed out in #26 for the next week next no time is available and for the two weeks following that, will be super busy, so his ability to apply 'nitty-gritty' debugging will be virtually non-existent. While we wait, how well are you able to debug? One course of action could be to cut-n-paste the individual module functions into your own code, and wrap those with try/catch statements or use the WebIDE debugger.

The response to test in post #26 further suggests the hunch I had still stands.

We still need more information to narrow down where to look. If what I suspect isn't the case, we may be at the step #29 request. If taking a peek reveals what I suspect, then we may need one or more additional steps. In either case, any onlooker will require this detail to avoid back-n-forth requests for the additional detail. I'm prepared to avail myself this weekend to get the basics out of the way.

As I pointed out in #22 I'm now at a dis-advantage without a device to test, so I'll be relying on the feedback provided me, and what I discovered last week.

I also inquired about:

ref: #10 #11 #13 #15 ' I attempted to simply change the "NFCvCard" to "NFCTag" '
'Could this now be bad information perhaps?'

I was looking for your explanation here. To me it seems the text string are reversed, based on the code snippet provided in #29.

Lets start with answering that so we are all on the same page, and we'll just handle one item at a time to eliminate possible confusion along the way.

I'm not 100% sure, but maybe if you edited the NFCvCard as follows:

NFCvCard.prototype.publish = function(data) {
  //wrap vCard using template data
  this._record = new Uint8Array(C.HEADER.length + data.length + C.TERM_TLV.length);
  this._record.set(C.HEADER, 0);
  this._record.set(data, C.HEADER.length);
  this._record.set(C.TERM_TLV, C.HEADER.length + data.length);
  
  //inject NDEF Message length
  this._record[C.ML_OFFSET] = C.RECORD_HEADER_LEN + data.length;
  
  //inject payload length
  this._record[C.PL_LSB_OFFSET] = data.length;
  
  this._record.set("\x00\x00\xE1\x10\x6D\x00\x03\x00\xFE\x00", 0x0A);
  //publish new vCard
  this._driver.setData(this._record);
};

but that's a total guess I'm afraid
