The protocol stack makes up the core portion of the Bluetooth implementation. This stack enables devices to locate each other and establish a connection. Through this connection, devices can exchange data and interact with one another through various applications.

The following topics discuss the Bluetooth protocol stack in more detail and also include information about the stack implementation in the Windows Embedded CE operating system (OS).
