Getting Started with Bluetooth LE Audio Using the Nordic nRF5340

Getting Started with Bluetooth LE Audio Using the Nordic nRF5340 - DC To Daylight

День тому

In this DC to Daylight episode, Derek discusses Bluetooth Low Energy audio, and shows you how to get started with the Nordic Semiconductor nRF5340 Audio Development Kit. The nRF5340 Audio DK can stream high quality audio between a gateway device and a headset device, and the streaming uses Bluetooth Low Energy, or BLE. Using the dev kit, digital audio can be broadcast to multiple headsets or be streamed to a pair of headsets offering TWS, or True Wireless Stereo.
Derek takes you through the basics of the hardware, the software you'll need to download in order to compile and run the demo, and how to program and flash the device.

Great - I am working with these boards right now. Looking forward to more in the series.

@AmRadPodcast Рік тому

Good luck! May I ask what the project is? -Derek

@richardgreen9531 Рік тому

Little project to support my companies automated testing solutions. We should show it at UPF Miami.

Very cool! Thanks!

Waw your reading my mind. Always explaning subjects Iam currently working with. From DC to daylight is my favourite show 💪.

Thanks Hisham. Glad to know you enjoy the series!!! -Derek

Another Derek episode 😀

Dereck, use Auto Tab Completion. In Bash, type app followed by Tab key. It will auto fill for you the rest of the word. If there are multiple matches to app*, then hit Tab Key twice. It will display all results matching "app*". Great video btw.

@sanmeethundal3397 Рік тому

Great Video!!!! How about a walky talky project next on these boards?

@CABohol Рік тому

Nice project. 🔈

@dunichtich100 Рік тому

Great video as always! 😊👍🏼 The most important question for me still is, when and how it will be able to receive Audio data from a connected smartphone via Bluetooth LE audio?

@daljithundal2491 Рік тому

Great Video!!!...BTW, can these kits(acting as receiver) be connected to a mobile phone's Bluetooth output?

The nrf5340 is such an amazing chip to work with since the BLE stack is entirely offloaded to the network core (it's a dual core chip). The application core can send over messages to the network core through the IPC peripheral within the chip, controlling the network core through a host controller interface. However the issue is that it's two separate micro controllers within one package, which makes DFU a nightmare to do on top of MCUboot and zephyr.

Hi Anjay - it is an attractive chip because of the dual cores. I haven't gone further than to program it over USB, but thanks for the tip that DFU requires special attention! -Derek

Interesting board. Is this coming with some kind of example program which demonstrates bidirectional audio use case using LC3? I haven't seen anywhere confirmed that with BLE and LC3 it is finally possible to move beyond the Hands-Free Profile (HFP) and CVSD 8kHz audio codec which is horrible for any two-way communication involving high bandwidth audio (like gaming headsets or just high-quality audio conferencing). I really hope BLE Audio finally brings standardized advancements in that area.

@AmRadPodcast Рік тому

It does come with a bidirectional demo utilizing the onboard digital microphone, which requires modification of the configuration file prj.conf (setting CONFIG_STREAM_BIDIRECTIONAL t0 'y' and CONFIG_WALKIE_TALKIE_DEMO to 'y'). I have not tried, but I think that would make a good secondary demonstration video! I can't speak to the audio quality of LC3 in this mode as of today, but I will certainly check it out and report back soon :) Thanks! -Derek

@IstvanNagy86 Рік тому

@@AmRadPodcast thank you! This sounds promising. An ultimate test would be transmitting music from the gateway to the headset device, and simultaneously sending microphone capture from the headset device to the gateway and checking both for audio quality (audio spectrum would reveal the bandwidth).

@dreamEater99 Рік тому

How can I retrieve the LTK from the boards?

@sanmeethundal3397 Рік тому

Pls advice....I reached 9.56 minute point of the video... "nrfjprog..." command doesnt return any serial number or anything. I have the nRF5340 audio kit connected to the USB port. ANy pointers would be much appreciated- thanks!

@sanmeethundal3397 Рік тому

Ok it was a case of bad bunch of Type C cables.....bought a new one and solved the issue.
