https://devzone.nordicsemi.com/f/nordic-q-a/4142/device-manager-failsHi Maybe you can help me. I&#39;m trying to get Device Manager to work, but I&#39;m having several problems. Although the Device Manager is being correctly initialized and the connection context is being correctly saved into flash memory, I&#39;m getting theseen-USTelligent Community 13Mon, 20 Oct 2014 10:01:48 GMThttps://devzone.nordicsemi.com/thread/14812?ContentTypeID=1Mon, 20 Oct 2014 10:01:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c2609eab-ab98-4d55-80d5-99e5102abe09Elena<p>Hi again</p> <p>I haven&#39;t found the device manager example I asked in my previous message, but comparing to the Bond Manager example (<a href="https://github.com/NordicSemiconductor/nrf51-ble-app-lbs/tree/require-encryption-5.1.0)">github.com/.../require-encryption-5.1.0)</a> I have found in <a href="https://devzone.nordicsemi.com/question/5191/nrf51822-peripheral-with-passkey/">this</a> thread, I have why Device Manager was failing.</p> <p>The problem looks to be that in my application, I was processing the events BLE_GATTS_EVT_SYS_ATTR_MISSING, BLE_GAP_EVT_AUTH_STATUS and BLE_GAP_EVT_SEC_INFO_REQUEST both inside my own application, and by device_manager_peripheral.c. I&#39;m not an expert in BLE, but looks these events must only being processed by device_manager_peripheral.c.</p> <p>After removing the instances to these events inside my own on_ble_evt function, Device Manager has started to work correctly.</p> <p>Cheers,</p> <p>Elena</p> <p>UPDATE: Although the bonding process is working with Master Control Panel, I&#39;m experimenting several problems when working with iOS. The version I&#39;m working is iOS 8. I would like to try with iOS 7 to be sure if the problem is the iOS version or my application.</p><div style="clear:both;"></div>
