BLE stack

Hi ,

This is the basic architecture layer which I have found out :

Host side we have : GAP and GATT protocol interact with the Security manager (SM) and the attribute protocol (ATT) Which interacts with the L2CAP protocol to send the data to the controller .

Controller side we have the following : HCI protocol which forms the interface with the link layer

Is this architecture fine to proceed ? Also what is the next step I need to do to refine this ? Thank you
