• Minimum Operating Systems for EchoAccess™ Mobile App

    The EchoAccess Mobile App is used in conjunction with the EchoAccess Interface to control and configure many Unison Echo® products conveniently from your Smartphone. The EchoAccess Interface and the EchoAccess Mobile App communicate using Bluetooth Smart (also called Bluetooth Low Energy, or Bluetooth LE) version 4.0 or greater. Some older Operating System may not support Bluetooth Smart and therefore will be unable to connect with the EchoAccess Interface. The following Operating Systems are supported:

    • iOS 8
    • iOS 9+
    • KitKat 4.4
    • Lollipop 5.0+

    Note: We have seen some lower cost devices that use a supported Operating System but do not have hardware or software capabilities to be Bluetooth Smart compatible. Please check the specs of your device to be sure.

    UPDATE: 4-12-18:  iPhone 5, iPhone 5c, iPad 4, and earlier devices are no longer supported as of EchoAccess Mobile App v2.3.348.
