I don't know if a keyboard emulation device needs it, but to use the
LibreOffice Impress app on my phone I need to configure Impress. From
the Help file:

> Enabling Impress Remote control in LibreOffice Impress To run an
> Impress slideshow, you must allow Impress to be controlled by the
> mobile device. Proceed as follows: 1. Open LibreOffice Impress. 2.
> Go to Tools – Options – LibreOffice Impress – General. 3. In the
> presentation options, select the Enable remote control checkbox and
> click OK. Close LibreOffice Impress and start it again.
