The Priva Compass consists of two parts. Both of these parts should be kept at the latest version. The Blue ID C4 Controller oversees the operation of all the equipment and the Gateway is the interface between the Controller and the outside world.
Each of these two parts has a separate installation file.
During the installation, you will be asked to upload two .zip files: the Controller Setup Package and the Gateway Setup Package. These packages are also needed for updating the Controller and the Gateway.
The Controller Setup package will update your controller to the latest software version (release at December 14, 2018 version 68181130).

The Gateway Setup package will update your Gateway to the latest software version (released at December 14, 2018 version 2_4_4_2018120516).
