Hi Microsoft team, I am developing a UWP app, the function is screen share sink and able to send UIBC to source side. Source side is Android app. The screen share function works well by using "Windows.Media.Miracast" API. But I don't know which API supports UIBC function. I want to query which API is used for sending UIBC to source side? such as: send mouse and keyboard event to source side. Or no public API to support UIBC?

Hi @Damon Pan , In the Windows.Media.Miracast namespace I found you can get input device through MiracastReceiverConnection , and MiracastReceiverInputDevices Class can return a keyboard , you can try to implement the UIBC function through this.

Hi Microsoft team,

I am developing a UWP app, the function is screen share sink and able to send UIBC to source side. Source side is Android app.

The screen share function works well by using "Windows.Media.Miracast" API.
But I don't know which API supports UIBC function.

I want to query which API is used for sending UIBC to source side? such as: send mouse and keyboard event to source side.

Or no public API to support UIBC?

Hi @Damon Pan ,
Welcome to Microsoft Q&A!

Now there are no tutorials and samples for Miracast in the official documentation. I also checked in Windows.Media.Miracast namespace, and there is no API related to UIBC or similar functions.

I will confirm with the team whether there is a way that can implement UIBC function in UWP.

Thank you,
Junjie

Thank you very much Junjie for comments.
Please help to confirm how to implement UIBC in UWP.
BTW, I checked windows preload app "settings -> System -> Projecting to this PC -> Wireless Display", it supports UIBC function.

Hi @Junjie Zhu - MSFT ,

As per your answer some keys on keyboard are working but not all the keys. How to integrate Mouse and Touch input using the MiracastReceiverConnection, and MiracastReceiverInputDevices class. The documentation part on the Microsoft website is not very clear for UIBC implementation.
Also how we can map mouse to Gamecontroller?
