ble-nfc's Introduction

BLE-NFC

[] [] []

1. Application will work in two modes

BLE Server/Card Emulation Mode

        Screen will contain Edit Text, Text View, 4 buttons (1st for BLE, 2nd for NFC, 3rd for Encrypt, 4th for Advertiser Mode)

BLE Client/NFC Reader Mode

        Screen will contain 2 Text View, 3 buttons (1st for BLE, 2nd for NFC, 3rd for Scanner Mode)

BLE Communication

2.1. Server Mode

             User will enter any text in Edit Text
             User will click Encrypt button, on click text will be encrypted using AES-256 Algorithms with
		   Key = 60CA0C1AC45776EF7C42C958F2A009107348D0F3B858F32691B3EABF3DC5B2FF
	     Encrypted text will be displayed on Text View
             User will click on BLE Button. On click GATT server will setup and start advertising.

2.2. Client Mode

             Screen will contain 2 Text View, 2 buttons (1st for BLE, 2nd for NFC)
             User will click on BLE. On click, BLE Scan will start and connect to GATT Server and read encrypted data.
             Client will decrypt data and display Encrypted Data on 1st Text View and Decrypted Text on 2nd Text View.

NFC Communication

3.1 Card Emulation Mode

            Same as step - i and ii in 2.1 for BLE.
            User will click on NFC button. On click Encrypted data will be ready for transmission through NFC.

3.2 Reader Mode

   	    # Same as step-i in 2.2 for BLE.
            User will click on NFC. Device will start as NFC Reader.
            Card Emulating device will be tapped on Reader device so data encrypted data will be received by reader.
            Same as step-iii in 2.2

Note –

       For BLE, feel free to use any UUID for GATT Service and GATT Characteristic.
       For NFC, Use AID: A0000001010101 and create command as per your convenience.
       If your device supports BLE and NFC, then test as well otherwise complete the code and send.
