The Partner Demo Image comes with the Update Factory service and UI client pre-installed. If you ever need to re-install or update them, have a look at the dropdown below:

Update Factory Target Support

It is then possible to add devices to your targets. At the dashboard, click the plus (+) sign on targets panel and follow the instructions.

To connect the device to the dashboard, a configuration file has to be pushed to Android's file system. Follow this article to create the ufConf.conf file according to your security keys, then push it to the device:

adb push ufConf.conf /sdcard/UpdateFactoryConfiguration/ufConf.conf

Your ufConf.conf file should be similar to:

ufConf.conf
tenant=<Your Tenant> url=https://personal.updatefactory.io/ controllerId=<Chosen Controller ID> gatewayToken=<From System Config> targetToken=<From Device Details> apiMode=true enable=true updateFactoryServer=true

Reboot the system to apply the file change. It is now possible to check the current communication status from the UI application or from Android's notification system. For a comprehensive list of Machine States, go through Kynetics's own documentation. If the log says (WAITING, SLEEP_REQUEST) -> WAITING, the system has connected to the dashboard and is ready for receiving instructions. If it raises an error, recheck your ufConf.conf file with the documentation.

The following video shows how to send OTA updates to the devices. Just drag a distribution from the distribution's list to target module and choose between a soft or forced update, according to the video. Follow the prompts on the android device. For more information, be sure to visit Update Fatory's documentation page.

Next Steps

From now onwards, you are able to use Android development tools to create your own Android apps. Refer to the Android developer website for documentation.

Kynetics has a comprehensive documentation website named Technical Notes as well as the Update Factory documentation.
