Prepare the Raspberry Pi

Open

• We use the Raspberry Pi model B

• Install Raspbian (as part of NOOBS, we use NOOBS 1.3.9)

• If are connecting your SmartMesh IP Manager through the UART pins:

  
  By default, the Raspberry Pi uses the UART pin as a command line interface for Linux. After the first boot, you need to configure Linux to not use those pins:

  • In /etc/inittab, replace

    T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

    with

    #T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

  • In /boot/cmdline.txt, replace

    dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait

    with

    dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait

  • Reboot the Raspberry Pi so these changes take effect

    sudo shutdown -r now

Hardware Connections

We are connecting the serial API port of the SmartMesh IP manager to the UART on the Raspberry Pi.

Happy together

Install DustLink

The Raspberry Pi comes with Python 2.7, so you can run any application developed using the SmartMesh SDK. Here, we will run DustLink:

• Download the latest release from https://github.com/dustcloud/dustlink/releases on your computer, as a zip file.

• Transfer it to your Raspbery Pi, for example using SCP.

• Enter the following commands to install DustLink (you only need to do this once)

  pi@raspberrypi ~ $ unzip dustlink-REL-1.0.2.63.zip pi@raspberrypi ~ $ cd dustlink-REL-1.0.2.63/ pi@raspberrypi ~/dustlink-REL-1.0.2.63 $ sudo apt-get install python-setuptools pi@raspberrypi ~/dustlink-REL-1.0.2.63 $ sudo easy_install pip pi@raspberrypi ~/dustlink-REL-1.0.2.63 $ sudo pip install -r requirements.txt

• Start DustLink

  pi@raspberrypi ~/dustlink-REL-1.0.2.63 $ cd bin/dustLinkFullWeb/ pi@raspberrypi ~/dustlink-REL-1.0.2.63/bin/dustLinkFullWeb $ sudo python dustLinkFullWeb.py

• In your browser, open http://<your_raspberry_pi_ip_address>:8080/

  Open

  

Configure DustLink

• Log into the web interface using:

  • username: admin

  • password: admin

• Navigate to Managers

• Under the Add section, enter /dev/ttyAMA0 and press Enter. After 10s, this connection is active

  Open

  

• Refer to the DustLink documentation for information on using DustLink.

Start DustLink on boot

• Install screen:

  sudo apt-get install screen

• Create file /home/pi/startDustLink.sh with the following content:

  #!/bin/bash cd /home/pi/dustlink-REL-1.0.2.63/bin/dustLinkFullWeb python dustLinkFullWeb.py

• Change ownership and permission for that file and the DustLink folder:

  sudo chown pi:pi /home/pi/startDustLink.sh sudo chmod 744 /home/pi/startDustLink.sh sudo chown -R pi:pi /home/pi/dustlink-REL-1.0.2.63/

• Have cron start DustLink on reboot:

  crontab -e

  then, add the following line:

  @reboot screen -dmS DustLink bash -c "/home/pi/startDustLink.sh"

• Reboot the Raspberry Pi

  sudo shutdown -r now
