SDP (Service Discovery Protocol)

Service Discovery Protocol (SDP) is a communication method used by devices to identify and locate services or resources available on a network or connection. For example, in Bluetooth, SDP allows devices like phones and headphones to find and connect to each other’s services—such as audio streaming or data transfer—without manual configuration. It helps streamline the connection process by enabling devices to automatically discover what services are available, facilitating easier and more efficient interactions between hardware or software components within a network or device ecosystem.
