Our Bluzone app for iOS can be easily downloaded and installed on your iOS device from this link. The latest version is: 1.15 (Build 2950).
Please see this page for a step-by-step walkthrough on how to get started with our Bluzone Cloud and the Bluzone iOS app.
There are no extra steps required to get your beacons updated to our latest firmware. These updates are part of the beacon provisioning process within the Bluzone app - as described in the linked document. Whenever you use this app to provision a beacon, a firmware update will be applied automatically if available. Once your beacons are provisioned and registered in the Cloud, all subsequent firmware updates can even be done automatically by a Blufi device - if available in your project and in range of your beacons.
