Requirements for the Eko Windows app

The Eko Windows app can only be used with Windows 10.

PC requirements

Windows 10 version 1803 and newer.
4GB RAM, 8GB RAM recommended.
The PC will need an audio output source (speaker/headphones) for proper app functionality.

Eko requirements

Bluetooth 4.2 connection.
The second generation Eko CORE is only compatible with Windows 10 PCs and Eko Windows app v1.5.0 and above.
Only Eko DUOs with firmware version 3.6 or above will connect effectively with the Eko Windows application.
We recommend this BLE dongle if native BLE drivers are not able to initiate an Eko stethoscope connection.
Some users may receive an error message upon downloading the application: “This application requires Microsoft Visual C++ 2017 X86 14.1 or greater.” Users can download this from the Microsoft website. Please make sure that x86: vc_redist_x86.exe is the option downloaded. The Eko Windows app should then install without issue.
