https://devzone.nordicsemi.com/f/nordic-q-a/80162/nrf-connect-sdk-zephyr-vs-standalone-nrf5-sdkHi Team, I have a few questions regarding nRF5 SDK and nRF Connect SDK. I have previously used nRF5 SDK for two years, with and without freeRTOS. We might be making a new product with nRF52840 SoC. Will Nordic continue to support the nRF52 Seriesen-USTelligent Community 13Thu, 30 Sep 2021 12:17:57 GMThttps://devzone.nordicsemi.com/thread/331922?ContentTypeID=1Thu, 30 Sep 2021 12:17:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a0f84189-d109-4e15-8893-4afafcdd063e&#216;ivind<p>Hi,</p> <blockquote> <p><span>Will Nordic continue to support the nRF52 Series with the nRF SDK and Soft devices?</span></p> </blockquote> <p>We recently released a statement on nRF5 SDK and nRF Connect SDK, which answers this and many other questions you may have:&nbsp;<a href="https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nrf-connect-sdk-and-nrf5-sdk-statement">https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nrf-connect-sdk-and-nrf5-sdk-statement</a></p> <blockquote> <p><span>Having said that,&nbsp;</span><strong>my second question</strong><span>&nbsp;is that how much is Zephyr RTOS tied with the main nRF Connect SDK?

None of the nRF Connect SDK features are available without Zephyr RTOS.</p><div style="clear:both;"></div>
