Then you can use <a href="https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF51822#Downloads">SoftDevice S130 v.2.0.1</a>.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/65340?ContentTypeID=1Thu, 13 Oct 2016 10:54:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:05c4a019-8056-4adc-aeb7-db22a54c0e95OlegT<p>Example of project exactly for my chip nrf51822-**ab and I&#39;m try it with SDK 6.1 and SD s110 v7.3.0.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/65339?ContentTypeID=1Thu, 13 Oct 2016 08:10:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:28979cbd-81d8-46cf-bc1d-2353a1ce889dAlex<p><a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf51%2Fdita%2Fnrf51%2Fcompatibility_matrix%2FnRF51422_nRF51822_ic_rev_sdk_sd_comp_matrix.html">Compatibility matrix</a>.
