NFC Example Source Code: Does Not Read NFC Tags

[admin]

I'm using a tutorial source - without changing it at all - and it won't read an NFC Tag.

When I scan a tag - it does nothing.

It is SUPPOSED to read an NFC Tag written as: WIFINETWORKNAME,password

^ - I think - the tutorial states "write network name and password (separate by comma) into the tag" and I've tried it 3 different ways - nothing works.

Nor does it create a new wireless profile - no matter what I do.

What it does do:

Launch when I scan an NFC tag (If I write the AAR to the tag)

What it does not do:

<ul>
<li>Create any new wireless profiles</li>
<li>Read the NFC tag and/or connect it properly</li>
</ul>

What I've tried to do:

Write then read the NFC tag as:

WIFINETWORKNAME,password

WIFINETWORKNAME, password

WIFINETWORKNAME , password
