Learning nRF5 SDK Vs nRF Connect SDK

[Sujitth]

Hi,

When starting to learn nRF currently, is it better to start with nRF5 SDK or nRF Connect SDK?

I know Nordic will not add new features to nRF5 SDK, but what if I want to work with devices like nRF51822? I have to go back to nRF5 SDK?

and I have installed nRF Connect SDK 1.9.0 for VS Code previously and now 2.0 has been released, but it is not showing in the Toolchain Manager app.
What is the proper method to uninstall and update nRF Connect SDK 2.0?

Thanks.

Hi,

For new projects, we recommend nRF Connect SDK. This is where new development will happen, this is where we have our newest features and this is where new SoCs and features will be supported. See our nRF Connect SDK and nRF5 SDK statement for details.

Regarding the nRF51 series, the Bluetooth stack of nRF5 SDK is not available for new designs. The stack was built for Bluetooth Core Specification v4.1, which is currently deprecated and gets withdrawn on February 1st 2023. See What impact does the deprecation and withdrawal of Bluetooth Core specification v4.0 and v4.1 have on your current and future products? for details on deprecation and withdrawal of old specifications.

nRF Connect SDK v2.0.0 is available through version 1.0.0 of the toolchain manager. You are currently on version 0.10.3. Please note that the default SDK install path changes for Toolchain Manager v1.0.0, so if you are using the default install path then Toolchain Manager may not see previous installs. To get them back, you can change the install path back under the SETTINGS tab of Toolchain Manager.
