Hi Alistair, I'm attempting to get into NFC on Android by communicating with a custom > PN532 device, however I'm a little confused as to my options and the > Android protocol. > > - NFCIP-1, is it possible to place my device as a target into this > mode, for Android to automatically detect and communicate with to load an > app > > Android's foreground NDEF push/beam is based on NFCIP-1 (+ LLCP), so you can exchange NDEF messages between an Android device and the PN532 in peer-to-peer mode. See http://code.google.com/p/ismb-snep-java/ (or the older http://code.google.com/p/ismb-npp-java/ ) for an example of how to communicate with Android apps in peer-to-peer mode. The ACR122U that is used in this examples contains a PN532, so it should be easy to adapt them to your custom PN532 device.

This is also possible.
