https://devzone.nordicsemi.com/f/nordic-q-a/82397/nrf52805-project-in-sdk15-3Hello, I have nRF52811 project which I would like to transfer to nRF52805. It is using SDK 15.3. I saw this tutorial: https://devzone.nordicsemi.com/guides/short-range-guides/b/getting-started/posts/developing-for-the-nrf52805-with-nrf5-sdk Iten-USTelligent Community 13Mon, 06 Dec 2021 14:02:41 GMThttps://devzone.nordicsemi.com/thread/342105?ContentTypeID=1Mon, 06 Dec 2021 14:02:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a33c6397-11fa-4e5a-9b46-3c4e48e0c612Simonr<p>Hi Miloslav</p> <p>I would recommend going the other way around in order to do this, as SDK v15.3 doesn&#39;t support the nRF52805 by default. I would recommend migrating your application to SDK v17 instead, following the migration guides for SDKs <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/migration.html">16 </a>and <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/migration.html">17</a> before transferring your project to match nRF52805.</p> <p>Is there a specific reason you don&#39;t want to move to SDK v17? To patch the files to make this work in SDK v15.3, you&#39;ll also need to add board support for the nRF52805, but this has not been tested at all, and we would not be able to guarantee that it will work, even though I don&#39;t see a reason why it shouldn&#39;t.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
