/*******************************************************************************
* Function Name: StackEventHandler()
********************************************************************************
* Summary:
* Event handler for the BLE events processing.
*
* Parameters:
* uint32 eventCode: The event to be processed
* void * eventParam: Pointer to hold the additional information associated
* with an event
*
* Return:
* None
*
* Theory:
* The function is responsible for handling the events generated by the stack.
* It first starts advertisement once the stack is initialized.
* Upon advertisement timeout or disconnect events, this function sets a flag
* to indicate to the main() function that it should enter Hibernate mode.
*
* Once the device is connected, this function initiates an authentication
* request. It displays a 6-digit passkey on the UART output on a PC and asks
* the user to enter this key on the iOS device (NP) side.
* Once the authentication is complete, the function starts the discovery
* procedure to know whether ANCS service is supported by the peer device.
*
* When the automated service discovery is complete, the function starts a manual
* discovery procedure for the ANCS service (since the BLE component does not
* handle discovery of custom services yet - that will be added as part of
* Creator 3.2).
*
* When the automated service discovery is complete and the ANCS service is not
* found, the function subscribes to the Service Changed characteristic
* indication to know if and when the iOS device adds ANCS support later.
*
* Once the ANCS service is found and a new GATT Notification comes for any of
* the ANCS characteristic, it calls the corresponding function in ANCS.c.
