https://devzone.nordicsemi.com/f/nordic-q-a/19649/nrf5-sdk-12-nrf52-preview-dkI have been trying to use nRF5 SDK 12 on nRF52 Preview DK by using PCA10040 instead of the removed PCA10036. But example &#39;ble_app_hrs&#39; that uses SoftDevice S132 v3.0 do not work on nRF52 Preview DK. Is it expected? the same example fromen-USTelligent Community 13Mon, 13 Feb 2017 12:20:44 GMThttps://devzone.nordicsemi.com/thread/76462?ContentTypeID=1Mon, 13 Feb 2017 12:20:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5f1db891-b9ed-400a-b8c8-c4f967636a3aFormerMember<p>The chip on PCA 10036 is an Engineering A chip, and the chip on PCA 10040 v. 1.1 is a revision 1 chip, see <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52%2Fdita%2Fnrf52%2Fcompatibility_matrix%2Fic_revision_overview.html&amp;cp=2_0_4">this</a> IC revision overview table.</p> <p>If you compare <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52%2Fdita%2Fnrf52%2Ferrata.html&amp;cp=2_2_1">the errata list</a> for Engineering A and revision 1, it may explain why examples working on PCA 10040 doesn&#39;t work on PCA 10036. Also, for the same reason, we do not recommend to use PCA 10036 for development. Therefore, I would not recommend you to port SDK 12 examples to S132 v.2.0.0, to make them work with PCA10036.</p><div style="clear:both;"></div>
