Should CCCD value be reset to 0 on connection?https://devzone.nordicsemi.com/f/nordic-q-a/915/should-cccd-value-be-reset-to-0-on-connectionHi Do the latest sample apps (for example, Heart Rate) which do not required bonding behave as follows:- make connection from iphone enable notification check value of cccd is 1 drop connection immediately make connection from iphoneen-USTelligent Community 13Mon, 18 Nov 2013 09:59:30 GMTRE: Should CCCD value be reset to 0 on connection?https://devzone.nordicsemi.com/thread/4428?ContentTypeID=1Mon, 18 Nov 2013 09:59:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f048fa0a-3391-4b4b-945a-298acbc3c100Ole Morten<p>Have you tested this with the Master Control Panel as well? I&#39;m not able to see this problem when using MCP 3.5.0 with ble_app_hrs from SDK 4.4.2, and I&#39;m also not quite sure I see how this would happen.</p> <p>When the CCCD values are needed by the softdevice, it is expected to give the application a BLE_GATTS_EVT_SYS_ATTR_MISSING event, to which the application should reply by doing a sd_ble_gatts_sys_attr_set() function call, potentially giving back a set of previously set values. However, when not being bonded, it is expected to just pass NULL for the pointer, to reset the values.</p> <p>This should be handled as needed by the bond manager in the SDK.</p><div style="clear:both;"></div>
