Dual mode on nrf5340 - Receive Bluetooth classic/LE->12s, simultaneous with i2s->unicast to different device

tomasz — Wed, 22 Jul 2026 09:11:32 GMT

Hi,

I am just evaluating the nrF5340 for an audio bluetooth project. I am trying to find out if the nrf5340 can receive bluetooth audio (classic or LE) from one device and transfer it to i2s out, at the same time as receiving i2s input and transmitting that out as unicast to a different device (or auracast). This would be for basic 16/48 stereo.

My understanding is that the nrf5340 can accomplish these tasks (especially with sample applications), but was not sure if it has the capacity to do this in dual mode like this at the same time.

Secondly I know there has been discussion previously about slave mode not working for i2s on the part (due to drift compensation) - is this still the case, or has there been any update on this?

Thanks for your help.

Joe

Certificate issue

tomasz — Thu, 11 Jun 2026 11:34:01 GMT

Hi,

We have onboarded several hundred nrRF9151 devices using the nRF Cloud "bulk onboard" UI (preconnect onboarding using device_credentials_installer.py). Generally, this works fine.

However, for two devices we are getting an error during onboarding: "certificate already exists". But the respective devices (UUID) are not present in nRF Cloud in any of our teams.

We're not sure why this is happening and how to resolve the situation and finish onboarding the two devices.

Any advice is appreciated.

Thanks

I would like to add ble_advdata_manuf_data_t to GATT when proxy-enabled, where should it be placed?

Hi there,

I would like to add some extra data to mesh-nodes, when not provisioned -- with ble_advdata_manuf_data_t usage. What is the best way to do it and where?

And, in case I would like to add ble_advdata_manuf_data_t to GATT when proxy-enabled, where should it be placed?

Thank you!
