Over the Air (OTA) Updates

OpenPV provides a set of services that allows displays to be updated over a Wifi internet connection. This feature requires the purchase of licenses that will get provisioned on the display which will then get registered in the Spark cloud services. The customer applications will also be uploaded to the Spark cloud server making them accessible over a internet connection. The display can then be updated via the Wifi link using the built in Loader, no additional code on the application side is required other than adding a menu item to access the loader.

The basic steps required to implement this feature are as follows.

Setup Project and Display In OpenPV

Create a Project in the "Projects" menu

Go to "Manage Modules" -> "Add Modules" -> "Purchase modules" and purchase a block of OTA licenses. A full list of licenses purchased and available will be displayed.

Open your application project and under the "packaging" tab select the project you just created and select the licenses required for this project.

In the "Packaging" tab Provisioning section first load the licenses to the target display then generate your project code and upload it to the Spark cloud server.

Go to "Manage Targets" then select the search to search tool spy glass and any devices provisioned with the OTA license will appear in the list.

Go to "Manage Applications" then select the search to search tool spy glass and any application registered in this project and uploaded to Spark will appear in the list.

In order for the display to have visibility of an application download they must both be at the same release track level. Use the Promote/Demote buttons to move either the display or Application to the desired release track as needed.

OTA Updates on the Display

At this point we will assume the display does not have any application code on it and when you power up it boots to the Loader screen (must have correct firmware version to match application).
