Do you find that the data is not being sent across the wire after a couple reads of an nfc tag? Arduino Serial monitor shows that data is being read by the NFC Shield, but nothing is being received on the iOS side.

Interesting...it seems to work fine with the miFare classic card that comes with the Adafruit NFC Shield. But other tags (I have some mifare style sticker tags) seem to mess things up. It will read them once, but then everything grinds to a halt. Will try to figure out what's up with that.

Hi Jon,
it has something to do with the length of the UUID.
I only tested it with 4byte UUIDs so the buffer is prefilled with 12 byte zeros. If there are more than 4 byte UUIDs, the buffer is messed up :-)

The demo sketch as some options for improvements.

Regards,
Michael.
