https://devzone.nordicsemi.com/f/nordic-q-a/1229/ancs-confusionHi, I&#39;m trying to set up an iOS app (which I know is working properly) with a nRF8001 using nRFGo studio. I do not have the nRFGo dev kit (only the 8001 dev kit) so I hooked up the 8001 with my Arduino Uno Rev3.

The only comment that I have in addition is that it is likely that ANCS may work for &quot;Just Works&quot; security and the newer releases of iOS may allow you to see the ANCS on the iOS without disconnecting and re-connecting.</p> <p>Q1: Yes but make sure you read the other thread as ANCS uses the the GATT client capability (Remote) of the nRF8001.</p> <p>Q2: No. That will not work.</p> <p>As I said again, do not use the NVM until your development is stable.</p> <p>Edit: I realize that you are not using the NVM of the nRF8001 to store the setup but you are using NVM on the external microcontroller. My comments are about using the NVM on the nRF8001</p><div style="clear:both;"></div>
