Hi,
I'm trying get acquainted with NFC capability of MIT app inventor, so I looked at the tutorial for the NFC cup game and downloaded it onto my Nexus 7. However, every time I scan a tag (Topaz 512), the tablet automatically reads it and says "Empty tag." I can't get my application to access it.

Any ideas on what's going on?
Thanks,
L.

are you writing to the tag first?

I've tried with tags that are written and with empty tags. Either way, the tablet itself reads it (and reports it empty if empty), but the cup game app does not seem to connect with tags at all.

I am having the same issue as Leen, using the same tags. Simply using the "write" function in AppInventor is not actually writing the tag; instead, a dialogue about a "New Tag" pops up, which seems related to the Tag Dispatch System...

Jos, which tags specifically have you had success writing to using AppInventor? I'm happy to just buy whatever you're using.

Best,

I am beginning to suspect that AI2 is simply not compatible with the tags I am using. I am using Topaz 512 tags, which are NFC forum type 2. Should I switch?

Thanks in advance,
Leen

Solution found!
For some reason, the none of the tags work right from the manufacturer. After I write a test message using the app NFC TagWriter by NXP, the tags are formatted and work perfectly with AI2

Go to Settings -> Application Manager -> Swipe in from the right until you are at the heading all. Scroll down and look for the app tags. Click on it and disable it
