audio stream to app

[Kashyap23]

Hi,I am now working with nrf5340 audio sample on nrf5340 audio DK .Here I can able to stream spho645 mic data to other dk board and able to listen using headphone .Now as per my requirement I need to stream data to app i am using NRF54L15 with custom board .I need to stream two mic data to app where that data will be used for plotting and converted to .WAV file in app side .How can i achieve this,I am not sure how the flow will be with app to stream data .I couldn't able to figure how can i achieve this.I can able to receive mic data with bare i2s code.I have already done with sending audio data using notifications but now I want to achieve with streaming.Also clear me whether will there be  any  change in audio quality or any other things we can observe?

Regards,

Kashyap

Hello Kashyap,

We don't have any support on the nRF54L15 and it doesn't have HW support for streaming multiple channels. For LE audio the recommendation is still the nRF5340 and the kit you have. You can send data from nRF54L15 to app, but not multiple channels as you are planning. 

 Nrf54L15 support LE Audio?  

If you are using BLE with a custom profile, you can get data through, but if you want to support and use the BLE audio profiles and implementations, you have to use a phone that supports this and a chip that supports this.

Best regards

what does custom profile in the context you mentioned?Is it regarding the data sending in notifications using gatt?

Any update on this?

Hello Kashyap,

I'd recommend you to have a look at the BLE fundamental course in our DevAcadamy. Specifically Lesson 4: https://academy.nordicsemi.com/courses/bluetooth-low-energy-fundamentals/
