Hello,

I recommend installing nRF Connect SDK automatically with the Toolchain Manager application within nRF Connect for Desktop. The steps are described here.

Let me know if you have any issues with the installation.

Kind Regards,
Maria

Hi  Maria,

I  used nRF Connect for Desktop as described Installing automatically， I encounter a another question when I build using VS Code, the error log as belowed.

I want to use nRF5340 Audio DK work, after I download the SDK 2.0.0 , do I need input another command as described on page nRF5340 Audio， Setting up the nRF5340 Audio repositories。

The definition of strtof is a part of the Zephyr SDK. Can you please check if you have a folder named zephyr-sdk within "opt" in your toolchain directory?
You can open your toolchain directory from Toolchain Manager.

This depends on which software codec you want to use. If you want to use the open source codec SBC, the two commands shown in steps 1 and 2 of the repository set up will be sufficient. When you are asked for credentials from GitHub, you can enter empty credentials, and the installation will skip the LC3 download.

You will also need to change configurations which are choosing LC3 by default into choosing SBC instead. These changes are described in the section after the setup: Selecting the audio software codec.

Best Regards,
Maria

Hi Maria，

thanks for your reply timely,

The flow I operated as belowed, can you help me to check it:

step1 :  download nrf connect desktop and command line tools, and install success;

step2:  download sdk 2.0.0 from nrf connect desktop;

step3:  Open Command prompt

then input  command 

> west config manifest.group-filter +nrf5340_audio
> west update

but this step update lc3 failed, I use SBC instead

step 4: Open VS Code

step 5: build with vs code environment

Is the flow corrected?

Yuyin

BRs,

Hello Yuyin,

The only step missing is the change of configuration from LC3 to SBC. You need to add CONFIG_SW_CODEC_SBC=y to the prj.conf in the nrf5340_audio folder.

Best regards,

Maria
