Setup and Development are sequential phases with different responsibilities.
| Phase | Use it for |
|---|---|
| Setup | Inspect the environment, install the nRF Connect SDK and toolchain, create a project, and run one verification build. |
| Development | Configure, build, program, debug, test, read logs, operate devices, and investigate deployed-device observability. |
Setup stops after a successful verification build. Programming a device and changing the application belong to Development.
Use a fresh chat when moving from Setup to Development. This prevents installer and operating-system context from competing with application, build, and hardware context.
