LE Audio on nrf52840

[Jash]

Hello,

I was looking for solutions to LE Audio and came across nrf5340. Later on diving deep into this I found that nrf52840 SOC also has BLE 5.3. So, my query was can nrf52840 be used to develop LE Audio applications?

I have also noticed the nrf52840 LE Audio Development kit, so I guess using nrf52840 SOC, I should be able to develop LE Audio applications. If so, what SDK support do I need to download?

Hi Jash,

It is possible to use nrf52840 to develop LE Audio applications.. but we recommend and provide official support to LE audio application development based on nrf5340 (nrf5340 Audio DK). You can find the details here: https://www.nordicsemi.com/Products/Bluetooth-LE-Audio

The nrf5340 Audio DK is the recommended platform for Bluetooth LE Audio products: https://www.nordicsemi.com/Products/Development-hardware/nRF5340-Audio-DK

The latest nRF Connect SDK v2.0.0 supports Bluetooth LE audio and have examples for the same: https://www.nordicsemi.com/Products/Bluetooth-LE-Audio/Development-Software?lang=en#infotabs

nrf5340 Audio application: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/nrf5340_audio/README.html

Hello Swathy,

I just checked the nrf connect SDK for nrf5340. I want to develop an audio streaming hearing aid. I have noticed the special feature section in the datasheet, wherein it is mentioned DSP instruction. Can you provide me with any information on how the data from smartphone to 5240 SOC will be transferred via BLE using SBC codec and any support regarding communicating with DSP.

Looking forward to hear from you as well as anyone who can help :)
