1. Software

The software for this Application Note is delivered in raw source files based on MCUXpresso IDE project.

• MCUXpresso IDE 11.7.0 or Later

2. Hardware

• KW45B41Z-EVK board as host MCU, used to load and run the Bluetooth Low Energy Stack and NFC application logic KW45B41Z-EVK
• NCF3320 Antenna v1.0 board as an NFC transceiver (With minor changes other NFC tranceiver (CLRC663,PN5180) can be supported)
• Wires for SPI communication
• Micro USB Cable
• Personal computer

Details on the connection between KW45B41Z-EVK and NFC reader board are listed here: Hardware setup and configuration

3. Setup

Use the following steps to get the environment set up.

This example assumes this repo is cloned into the "C:\work" folder.

3.1 Step 1 Setting up the development environment (SDK download, workspace)

Use these Details for setting up the environment.

3.2 Step 2 Flashing NBU

Information regarding flashing NBU can be found in section 2.4 and 3.3 of the Getting Started page of KW45B41Z-EVK (NBU is located into the: C:\work\an-kw4x-bluetooth-le-nfc-integration\kw45b41zevk_w_uart_ncf3320_basic_discovery\source -> kw45b41_nbu_ble_hosted_a1.sb3)

3.3 Step 3 Download & install NFC Reader library v5.22.01

Download the NFC reader library K82 NFC Reader Library package - PN7462AUPspPackageFull-v05_22_01 and install it into the "C:\work" folder.

3.4 Step 4 Integrate the NFC reader library

The current NFC Reader Library v5.22.01 does not support Kinetis KW4x MCU.

To add the support, apply the patches as below:

C:\work\an-kw4x-bluetooth-le-nfc-integration\nfc_patch>nfc_patch.bat "C:\work\PN7462AUPspPackageFull-v05_22_01\PN7462AU Software\PN7462AU-FW_v05.22.01_Full" "C:\work\an-kw4x-bluetooth-le-nfc-integration"
