Development model
The nRF Connect SDK follows a development model that gives users access to both stable releases and new features that are still under development.
The nRF Connect SDK is an SDK that is openly developed and maintained by Nordic Semiconductor. It is based both on code developed by Nordic Semiconductor engineers and on open-source software projects, which in turn are developed collaboratively by many contributors.
Users can continuously track the development progress of the nRF Connect SDK and even contribute to it. This includes both the Nordic-specific and the open-source portions of the SDK.
Any individual or company can choose to contribute to the nRF Connect SDK codebase. Contributions are welcome but entirely optional, as the licenses used by the nRF Connect SDK allow for free modification of the source code without a requirement to contribute the changes back.
