Bluetooth Automotive entertainment application question

chen_jackcw — Fri, 03 Nov 2023 07:22:35 GMT

Hi sir,

We are planning to design the automotive IVI including RSE. Is there any bluetooth solution that can connect with 3 passengers' bluetooth earphone, and I can use audio application to stream 3 different audio streams to these earphones. E.X. music 1 to earphone 1, music 2 to earphone 2, music 3 to earphone 3. Then every passenger can listen to their own music.

Thanks

Jack

Hi @chen_jackcw ,

Thanks for contacting NXP support.

NXP has a BLE audio device NXH3675 supporting Multi-Stream Audio feature. it support up to 7 audio streams in different unicast and broadcast topologies.

Here you can find some details: NXH3675: Ultra-Low Power, Low Latency LE Audio Solution | NXP Semiconductors

Hi Gavin,

I have another question about LE audio.

If it can support multiple audio sources and sinks, each source can unicast it stream to dedicated sink.

for example. 4 smartphone and 4 earphone, audio stream from phone 1 is to earphone 1, phone 2 is to earphone 2 etc.

Thanks

Jack
