https://devzone.nordicsemi.com/f/nordic-q-a/71676/should-we-update-nordic-nrf5-sdkMy company produces smart helmets and our products have always been using nRF5 v11 SDK on nRF52 chips for almost 5 years now. The latest nRF5 SDK is already on v17 https://infocenter.nordicsemi.com/index.jsp?topic=%2Fstruct_sdk%2Fstruct%2Fsdk.html&amp;cpen-USTelligent Community 13Wed, 17 Feb 2021 12:11:08 GMThttps://devzone.nordicsemi.com/thread/294829?ContentTypeID=1Wed, 17 Feb 2021 12:11:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f14d20ae-9462-4d29-a704-860c4c17b256Kenneth<p>Hello,</p> <p>I don&#39;t see any issue continue using nRF5 SDKv11 if you are developing on the nRF52832 and have already a stable product. If you want to use different variants of the nRF52-series (or want some of the new or improved features) you may need to transfer to a newer nRF5 SDK. One thing you should double check though, is that for the nRF5 SDK v11 there was an important errata fix missing (or not found yet), so make sure that your system_nrf52.c include errata_108() fix, if not you should download a newer nRF5 SDK and make sure you update this file in specific.</p> <p>Also check out this:<br /><a href="https://devzone.nordicsemi.com/f/nordic-q-a/12495/what-are-sdk-11-0-0-known-issues">https://devzone.nordicsemi.com/f/nordic-q-a/12495/what-are-sdk-11-0-0-known-issues</a>&nbsp;</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
