Now that I have a running Kapua instance, its time to look at the network edge to gateways and devices.<\/p>\n

Eclipse Kura<\/a>\u00a0is a Java\/OSGi-based framework for IoT gateways. A gateway is a devices that is distributed at the network edges and communicates with sensor or steering devices using cables, Bluetooth or other private networks.<\/p>\n

Sins Kura supports a rather broad range of small devices, my plan is to use a spare Raspberry Pi as gateway hardware.<\/p>\n

Unfortunately my old Raspberry PI B is from the first generation, based on the ARMv6 architecture with 512 MB RAM. Therefore I cannot base the OS on Fedora that needs at least Model 2 and ARMv7 or ARMv8 architecture, so that I need to use\u00a0Download Raspbian for Raspberry Pi<\/a>\u00a0 for this. I choose the small server set and write that to the SD card:<\/p>\n

unzip -p 2017-11-29-raspbian-stretch.zip | sudo dd of=\/dev\/sdX bs=4M conv=fsync status=progress<\/pre>\n
Now inserting the SD card into the Pi, connecting LAN and booting. By default, ssh is disabled so I had to connect a keyboard and monitor and do that manually.<\/p>\n
Login as user “pi”, password: “raspberry” (this should be changed asap!)<\/p>\n
systemctl enable ssh.service\r\nsystemctl start ssh.service\r\nhostname -I<\/pre>\n
(this will give you the IP address where to connect to.<\/p>\n
Now the fun can begin. I typically copy my ssh-key and login from my workstation:<\/p>\n
ssh-copy-id ~\/.ssh\/id_rsa.pub pi@<ip_of_pi><\/a>\r\nssh pi@<ip_of_pi><\/pre>\n
Now its time to install Eclipse Kura! Get the latest version from here<\/a>. Since I have the old Raspberry model I choose this one<\/a>.\u00a0 For the installation I mainly followed the\u00a0Raspberry Pi Quick Start<\/a>\u00a0documentation but I will show the steps here, too.<\/p>\n
After booting the Pi several steps are needed on the Raspbian OS: At first, the dhcpcd5 packages needs to be removed:<\/p>\n
sudo apt-get purge dhcpcd5<\/pre>\n
then its useful to install the gdebi command tool to find all dependencies needed:<\/p>\n
sudo apt-get update\r\nsudo apt-get install gdebi-core<\/pre>\n
And finally install Java:<\/p>\n
sudo apt-get install openjdk-8-jre-headless<\/pre>\n
Finally, the package can be downloaded and installed:<\/p>\n
wget http:\/\/download.eclipse.org\/kura\/releases\/<version>\/kura_<version>_raspberry-pi-2-3_installer.deb<\/a><\/pre>\n
Note: replace <version> in the URL above with the version number of the latest release (e.g. 3.1.1). Install Kura with:<\/p>\n
sudo gdebi kura_<version>_raspberry-pi-2-3_installer.deb<\/pre>\n
Since Kura will make use of a wifi card to connect to devices, I also inserted a wifi dongle. And now its time for a reboot!<\/p>\n
Kura starts up automatically and presents a web UI:<\/p>\n
http:\/\/<ip-of-pi><\/pre>\n
Username: admin\r\n\r\nPassword: admin<\/pre>\n
