The RDK Accelerator Home UI version 3 is the latest stable version (rdk-nextRDK_apps/6.0.0-rc4/accelerator-home-ui/settings.jsonjson#16 platformSettings version) of the RDK reference UI which provides a full featured UI with a modern minimalistic design using a dark theme.

...

UI initiates Bluetooth scan for HID profile to connect and pair with at this point with a configured time-out. How to put the RCU in Bluetooth pairing mode is dependent on the RCU design which is not within UI scope.

UIv3.9 onwards Navigator UI will prefer to use Remote Control plugin on supported platforms to pair with RCU instead of classic Bluetooth plugin. Only one plugin shall be used to onboard the RCU - if preferred Remote Control plugin is available it will not fall back to use Bluetooth plugin to scan and pair with RCU.

...

Alexa support

Preview Mode: Navigator UIv3 UI supports basic Alexa skills on aligning to Alexa Voice Integration Manual on a supported platform using Voice Control plugin.

Customization (Theme and Logo)

One among the new feature in this version of UI is it allows to change the focus color, background color and logo if an operator wishes to by making necessary changes in config.js. Default config.js for reference is as below.

const themeOptions = {
    partnerOne: {
      hex: 0xfff58233,
      logo: 'RDKLogo.png',
      background: '0xff000000'

      hex: 0xff91c848,
      logo: 'RDKLogo.png',
      background: '0xff000000'
    },
}

User can define an object inside theme options which need three parameters:

hex - Color accents on the UI. Default one is shade of orange.
logo - Logo at the splash and top left side on the home screen.
background - background color of the components.

User has to export a specific theme for it to apply through the UI and rebuild or re-gernerate the app bundle.

exportconst var CONFIG = {
    theme: themeOptions['partnerOne'],themeOptions = {
    language: localStorage.getItem('Language')!=null ? language[localStorage.getItem('Language')] : language['english']
