If are connecting your SmartMesh IP Manager through the UART pins:
You do not need to do these steps if you plan on connecting your SmartMesh IP Manager over USB. |
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 |
You do not need to do these steps if you plan on connecting your SmartMesh IP Manager over USB. |
We are connecting the serial API port of the SmartMesh IP manager to the UART on the Raspberry Pi.

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

Managers
Add
section, enter /dev/ttyAMA0
and press Enter. After 10s, this connection is activeRefer to the DustLink documentation for information on using DustLink.
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 |
