Recommended Nordic VS Code Plugin Versions

Note: Newer updates of the Nordic plugins can cause issues. The latest versions have really weird behaviours in a specific version, so it is recommended to use the following versions:

• nRF Connect for VS Code: 2025.5.152
• nRF DeviceTree: 2025.4.22
• nRF Kconfig: 2025.4.26
• nRF Terminal: 2024.9.14

If you experience problems, try downgrading to these versions.

• In the extension:
  Install/Manage toolchain → Install SDK → Download 3.0.2
