Julian,
Aruba Beacon App avaiable only in IOS, I already sent post with correction couple of minutes back.
Regarding beacon managment capabilites,
If an access point with the USB beacon or AP 320 series access point is chosen, the APs will collect information from the battery powered beacons and relay this through an Aruba controller to the Meridian cloud server for management.
In the case of Aruba Instant APs, the instant AP will connect directly with the cloud server. Note that the only port required to be opened on your firewall is the outbound HTTPS to the Meridian cloud server.
Regards,
Pavan
