1 Introduction
The purpose of this document is to describe how to use NFC-Bluetooth® Low Energy
development kit. It provides an easy way to evaluate NFC features in the combination
with Bluetooth Low Energy.
The NFC-Bluetooth Low Energy package consists of two HW Boards boards, QN9020
Mini Development board and NFC RC663 Plus Add-on board. Both boards and software
applications, used for demonstration, are described in next chapters.

3 Software Description
3.1 Introduction
This chapter describes software setup and how to run the NFC-Bluetooth Low Energy
demo application.
The purpose of the demo application is to manage data on the NFC tag through the
application running on a mobile device. The user select read or write command on the
device, which is sent to the NFC-Bluetooth Low Energy device via Bluetooth Low Energy.
When NFC-Bluetooth Low Energy device receives the command, it executes it and
sends the results back to the phone.
The demo also supports Over‐The‐Air (OTA) programming.
Software stack used in this demo is prepared for the NFC-Bluetooth Low Energy
development kit and smartphone. Demo application is split in two, the first application is
required for the NFC-Bluetooth Low Energy development kit and the second application
for the smartphone. The current version of the demo is supporting only iPhone.
Software stacks are custom developed for this solution to fit special requirements.
