MeCheck may run on various Windows platforms, with different feature set and requirements.  It may work:

  • On Windows 7
    • As a Source, Sink, or “Source and Sink” device.
    • Requires Intel Wi-Fi and latest Intel PROSet installed.
  • On Windows 8.1/10, with latest Windows updates
    • As a Sink device only
    • No special requirement on Wi-Fi module.

Upon execution, MeCheck may become available to establish Miracast session with a target Miracast device.
To work with a Sink device, Win7 MeCheck Source must be used.
To work with a Source device, either Win7 or Win8.1/10 MeCheck Sink may be used.

MeCheck application can be configured, ahead of connection, to manipulate individual settings of the upcoming Miracast session, which is necessary to test and debug different aspects of the target device.
The configurable settings include:

Setting HDCP2 SourceSetting HDCP2 SourceSettings GUI for HDCP2.x feature as Source
  • Wi-Fi Direct and WPS parameters,
  • RTSP parameters, and
  • Optional features (HDCP2, UIBC, etc.).

During each Miracast Session, users may operate on selected controls at run-time, including:

  • HDCP2 re-authentication and scrambling control of either video or audio stream,
  • More to come.

All MeCheck sessions generate comprehensive log files with configurable detail level, to be reviewed at later time.  Such log files may provide insight and guidance for Miracast developers while working on their own products.
