https://devzone.nordicsemi.com/f/nordic-q-a/1290/ancs-compatibleHello, I&#39;m using a nRF51822 CEAAB0, SDK 5.0.0 and S110 6.0.0-5.beta to make an Apple ANCS client and for now I&#39;m trying the ble_app_ancs example. I read that CEEAB0 arent compatible with sdk 5.0 and not tested with s110 6.0, but the example works!.

Also you should use the production-ready version of the 6.0.0 SD, both are available on MyPage.</p> <p>Regarding the compatibility of CEAAB0 with the 6.0.0 SD, if you look at the matrix in document nWP-018, you will see that this particular combination is labeled as:</p> <p>&quot;v6.x.x will be compatible but not production level tested on these chip variants. See the S110 SoftDevice release notes for more details on features and compatibility.&quot;</p> <p>That means that, although your example works, this is not production level tested, so even though you can develop on this chip, for mass production of your product you should switch to a more recent IC version that gives you full test coverage. You may experience unexpected problems during your development, such as the ones described in <a href="https://devzone.nordicsemi.com/index.php/0xdeadbeef,-722,-src-ll_adv-c">this thread</a>.</p> <p>Carles</p><div style="clear:both;"></div>
