Hi,

developer.apple.com/.../Specification.html

The Apple Notification Center Service is on the iPhone GATT Server. You need to setup the nRF8001 as a GATT client to access the iPhone GATT server. Drag and drop the Services you are looking for i.e ANCS on the "Remote" column of the nRFgo studio, this will make the nRF8001 GATT Client look for those Services. Remember to set the UUIDs correctly.

Use the proximity template for Arduino as the start point to add the ANCS pipes to the "Remote" and do the below modifications
nRFgo studio: Set the IO Capability to Display only
nRFgo studio: Set the Device Security to Security Required
Print the ACI_EVT_KEY_REQUEST to the Arduino serial monitor Type the key printed on serial monitor in the iPhone popup.

The ANCS pipes will not be discovered the first service discovery. Watch the Service Discovery bit in the ACI_EVT_PIPE_STATUS Look at the datasheet of the nRF8001 for System Events, www.nordicsemi.com/.../nRF8001_PS_v1.2.pdf

After bonding is successful the ANCS pipes will still NOT be seen.

Disconnect

Wait for a few mins

Re-connect to the iPhone, make sure that some apps are using the ANCS.

Now the Service Discovery will automatically run and you will see the ANCS pipes in the Closed pipes.

Open the ANCS Pipes that are closed using the ACI OpenRemotePipe. You need to wait for the first call to OpenRemotePipe to finish before calling the next OpenRemotePipe (ANCS has 2 Pipes that need to be opened). Additionally wait for Service Discovery to complete before doing the OpenRemotePipe.

Now ANCS is available and you can have fun.

Enjoy
