The way I would do it would be to update the advertising packet of the nRF51822 with a flag that indicated a button push occurred so no connection with the nRF51822 was needed. This would make the solution simpler from both ends.</p><div style="clear:both;"></div>RE: How to detect in iOS app event trigger by button pressed in nRF51822?https://devzone.nordicsemi.com/thread/56984?ContentTypeID=1Tue, 05 Jul 2016 08:45:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9f3a021d-57d1-4b9a-a331-6fd14a93e57d&#216;yvind Karlsen<p>Hi,</p> <p>You can follow the steps <a href="https://devzone.nordicsemi.com/tutorials/4/">this tutorial</a> which shows a basic interaction between the nRF51822 and a mobile device using the ble_nus servies.</p> <p>Best regards,</p> <p>Øyvind</p><div style="clear:both;"></div>
