 Hi there, welcome to CES 2024, my name is Min Koo and I support the STM32 wireless microcontrollers. Today what we're going to show you is ST's R-Cas LD audio demo. When we look at the Bluetooth audio solutions today, the options are either dual mode or Bluetooth classic only. Also these solutions use the ATDP profile with SBC compression to transfer wireless audio and custom proprietary solutions are used to achieve true wireless stereo. Whereas when we talk about Bluetooth LD audio, this is a Bluetooth version 5.2 feature that mainly introduces lower latency, a new high-efficient low-power audio codec named LC3, and R-Cas broadcast audio. R-Cas broadcast audio is a new Bluetooth capability that enables a transmitter to broadcast audio streaming to an unlimited number of Bluetooth audio receivers using isochronous channels where no pairing or connections are required. Over here the R-Cas broadcast demo consists of five STM32 WBA discovery boards and let me explain what these boards are doing. A device with a source audio roll can produce audio. Two source devices are connected to a tablet each. Source one is broadcasting audio from a video with our HR president and source two is broadcasting a playlist of audio tracks. Whereas a device with a sync audio roll can render audio. Here are three sync devices where sync one and two are connected to headphones whereas sync three is connected to a speaker. These sync devices can discover and receive a broadcast audio stream. Using the onboard push button, these sync devices can choose which source they want to be synchronized depending on which audio stream they want to listen to. An important advantage versus Bluetooth classic is that there's no noticeable delay between the video being played and audio streamed to ST. Lastly, if you replace this tablet to something else there are so many possible applications. A speech for hearing aids, having multiple source broadcasting for multiple languages at an airport, an audio sharing experience supporting true wireless stereo at a gym or concert. This audio demo can definitely become your starting point for your creative Bluetooth applications. Please visit ST.com in the link below to learn about STM32WPA Bluetooth audio solutions. Thank you.
