Nordic Case Info
  • Case ID: 332886
Options

nRF5340 LE Audio + nRF7002 or similar offering from Nordic

ChrisBon

We are currently working on a project that has these requirements:

BLE Audio (Broadcast)

BLE Central and Peripheral

WIFI 5/6 (5gHz and 2.4gHz)

BT classic would be nice to have, but not required.

Our current platform is based off the nRF5340 and we are using a sperate processor to provide the BT classic and WIFI (only 2.4Ghz).  We are thinking of adding the nRF7002 to our nRF5340 to provide the WIFI.  I found this thread which concerns me on this path:

 nRF5340 LE Audio + nRF7002 

Is this still the case, I know that the coexistence should be supported now as it was added in the later SDKs.  So is this a viable option ?  If not what other options does Nordic have that would provide the above requirements ?


Thanks

    Hi

    We don't deliver any products with BT classic I'm afraid, so that we can't help with, but since the post you link to here (as of NCS v2.6.1), the LE Audio application has been using the SoftDevice Controller which supports BLE coexistence with I.E. the nRF70 series Wi-Fi coexistence.

    However, what Maria mentions about memory requirements still holds true, and I don't think you can fit the Wi-Fi stack, the Bluetooth stack and an audio application onto the onboard flash of the nRF5340. This again would mean you can't have the nRF7002 using the QSPI and would have a bit slower data speeds on the nRF7002.

    Adding all these features to one application will thus be somewhat complex, but not impossible. It depends on what requirements you would need for the Bluetooth LE, LE Audio, and Wi-Fi stack in your application. 

    You could also look at the nRF54H20, which will be a lot more beefy with more memory and multiple cores to handle this better, but it's not quite production ready, and more information can be found there.

    Best regards,

    Simon
