    Notifications stop in CapSense Proximity Example when Low Power Mode disabled.

      Can anyone explain this behavior?  Using CY8CKIT-042-BLE-A Pioneer Kit running the PSoC_4_BLE_CapSense_Proximity Example and commenting out the #define ENABLE_LOW_POWER_MODE to disable low power mode so advertising occurs from reset and does not time out after 30 seconds appears to stop notification data from being sent.  Notifications are enabled in CySmart by writing and reading the CCCD value 01:00 to handle 0x000F but no CapSense data is present for the CapSense characteristic attribute (0x000E).  The Notify property even shows a check mark under Enabled on the right side of CySmart.

       

      What I want to do is avoid having to manually press the user button to start advertising and just have advertising start from reset.  Just disabling Low Power Mode starts advertising from reset but then there is no notification data.  Why should disabling low power mode stop notifications?
