Topic: PN532 (NFC) not capable of detecting eachother? (Read 1 time) previous topic - next topic

I purchased two PN532 shields from Seeed Studio (adafruit was OOS), in the effort to have them detect eachother.

In the library Seeed/Adafruit library I find that it only supports ISO14443A (mifare classic), is this a Chip limitation?

Both shields are running the same example readallmemoryblocks but unable to detect eachother.

Have you tried the peer to peer demo sketches? http://www.seeedstudio.com/wiki/NFC_Shield#Demo_2:_PtoPInitiator.pde_and_PtoPTarget.pde

NFC Shield antenna is designed to work within a range of 1cm.

If your devices are really that close together, what is the advantage of wireless?

kinda got lost in the initial example files, thanks for the suggestion, I hope this puts me back on track.

The main reason is the ability to communnicate with eachother (and transfer data) without the need to physically connect or pair with eachother.

similiar to NFC on phones where a simple touch executes a desired action.

Update:

With my mac, the arduinos installed and worked out of the box (no manual installation of drivers needed) for all the NFC example demos except any of the P2P.

When I attempted to run the P2P sketches, they compiled and uploaded without an error, but never actually ran in the serial monitor.

I decided to use two WIN7 machines (one for each arduino), installed the drivers, set the correct COM Ports, and successfully received acknowledgment within the serial monitor that both arduinos, with NFC shields were running the P2P and detecting eachother!

My next step will be to transfer and store data between two arduinos.
