Downloading Open NFC SDK Edition

Open NFC SDK Edition allows us to connect to the AVD, log in NFC communications, and simulate different tag taps and P2P taps.

How to do it…

We are going to download, extract, and verify the files used to connect the AVD to the NFC Simulator that allows us to test the NFC application without a physical NFC-enabled device with the following steps:

Open a new browser window and navigate to http://open-nfc.org.
On the left navigation menu, click on Downloads.
On the download list, select the 4.4.1 SDK release.
Extract the downloaded archive to the previously created NFCBook directory.
There should be a folder named core in it and at least two folders named connection_center and nfcc_simulator. The nfcc_simulator folder will allow us to simulate a tag tap or a P2P connection. The connection_center folder contains the software that allows the simulator to communicate with the AVD.
