So if you are developing a new application from start, it is a good SDK to use. Especially if you want new features, such as new Mesh models that are not in any of the SDKs already.</p> <p>The nRF5 SDK is a mature solution which will continue to be supported, but it will not be the focus regarding new features.</p> <p>Best regards,</p> <p>Marte</p><div style="clear:both;"></div>
