Is there an NFC API for the Sony SmartWatch 2?

Question

We want to write an Android App for the Sony SmartWatch 2 which uses the device's NFC functionality to read and write NFC tags (such as Mifare or DESfire cards). NFC functionality is heavily promoted for the SmartWatch 2, however, I couldn't find any information on an open NFC API so far.

My questions: Is there an open NFC API for the SmartWatch 2? If so, are there any restrictions on the mode of communication (Reader/Writer mode vs. P2P)? Where can I find related documentation?

Thanks, Markus

Answer 1

The NFC in the SW2 is only used for pairing it to a phone. Sony does not support any API to read tags or transfer data using the NFC in the watch.
