error: Aborting due to Kconfig warnings with VSCode+nRF Connect SDK(nrf\samples\bluetooth\peripheral_uart)

Hi everyone:

I try to build the project which i create by example bluetooth peripheral_uart in SDK v2.7.0

But it build fail

Hello,

Based on your location,  we have seen that the SDK is not correctly downloaded. How did you install NCS? Did you use nRF Connect for Desktop? If so, can you please try to hit the "Update SDK" and "Update Toolchain" buttons:

If that doesn't work, try the "open command prompt" button, and move into the nrf folder ("cd nrf"), and from there you type west update, and hit enter.

If, after that, building still doesn't work, can you please try a more standard build configuration? Does it work if you just build the peripheral_uart example using the nrf52840dk_nrf52840 board instead of the nRF21540 board?

Best regards,

Edvin

I use VSCode to install Toolchain and SDK, and I have used the nrf5340_audio_dk/nrf5340/cpuapp/ns board to build the project but also fail

[Edvin]

In that command window that you are in when you  try to build, try changing directory to c:/ncs/v2.7.0/nrf, and run "west update". What does that say?

BR,
Edvin

Thank you for helping me. I confim that I didn't pull the SDK neatly. Now I use v2.6.0 SDK creat the sample and success
