Raspberry pi device

Bluetooth LE & NFC door-opener application for Raspberry pi

This program is built to transform a fully equipped raspberry pi into a smart device for access control

For smartphone interaction it uses an Adafruit PN532 Breakout board and a standard Bluetooth 4.0 USB adapter.

For door opening and audio feedback, a custom circuit linked to GPIO pins.

Hardware prerequisites

• Connect Adafruit PN532 breakout board to Raspberry pi using UART PINs. Remember to free the UART in Raspbian (https://learn.adafruit.com/adafruit-nfc-rfid-on-raspberry-pi/freeing-uart-on-the-pi)
• Connect the Bluetooth 4.0 USB Adapter to USB port
• This is the circuit to build. A green led, a red led, a buzzed and a relay. Each controlled by a separate GPIO pin. Remember to set the correct PIN that you're using in actuator.js file. Software prerequisites

---

• Install last version of raspbian os on your raspberry-pi
• Open shell
• Install pip for python 2.7
• Install nfcpy

#install pyserial
sudo pip install pyserial
#install launchpad bazaar Version Control System
sudo apt-get install bzr
#enters the dir
md nfcpy & cd nfcpy
#get the branch of nfcpy
bzr branch lp:nfcpy

• Test installation of nfcpy

$  cd nfcpy/examples
$  python tagtool.py --device tty:AMA0:pn53x show

• Install blueZ 4.101 from sources

wget http://www.kernel.org/pub/linux/bluetooth/bluez-4.101.tar.xz
tar -xvf bluez-4.101.tar.xz
cd bluez-4.101
./configure 
sudo make
sudo make install

• Test installation of blueZ:

hciconfig 

should results in something like:

hci0:   Type: BR/EDR  Bus: USB
         BD Address: 00:1A:7D:DA:71:0C  ACL MTU: 310:10  SCO MTU: 64:8
     DOWN 
     RX bytes:467 acl:0 sco:0 events:18 errors:0
     TX bytes:317 acl:0 sco:0 commands:18 errors:0 

• Install node.js (precompiled version)

sudo wget http://node-arm.herokuapp.com/node_latest_armhf.deb
sudo dpkg -i node_latest_armhf.deb

• Test installation of node.js

node -v 

should results in something like:

v0.10.24

Installation

• Clone repo of this project

git clone https://github.com/spotsoftware/io-at-spot.git
cd raspberry

• Setup bluetoothd daemon as a startup service

sudo cp app/config/bluetooth.sh /etc/init.d/bluetoothd
sudo chmod uog+rx /etc/init.d/bluetoothd
sudo update-rc.d bluetoothd defaults

If you ever want to stop this service from executing on boot

sudo update-rc.d bluetoothd defaults

• Install npm packages

sudo npm install

Run

sudo node socket.js
