Telephony and Cable Replacement Protocol:

Telephony Control protocol: Binary (TCS Binary or TCS BIN), a bit oriented protocol, defines the call control signaling for the establishment of speech and data calls between Bluetooth devices.

Adopted Protocols:

PPP:PPP is the IETF Point-to-Point Protocol (Internet Engineering Task Force, IETF Directory List of RFCs) and PPP-Networking is the means of taking IP packets to/from the PPP layer and placing them onto the LAN.

TCP/UDP/IP: TCP/IP/PPP is used for the all Internet Bridge usage scenarios in Bluetooth 1.0 and for OBEX in future versions. UDP/IP/PPP is also available as transport for WAP.

OBEX Protocol: IrOBEX (Short name is OBEX) is a session protocol developed by the Infrared Data Association (IrDA) to exchange data in a simple and automatic way.

Advantages:

Using peer-to-peer connectivity, Bluetooth technology simplifies personal area wireless connections, enabling all digital devices to communicate automaticaly. Bluetooth technology also provides fast, secure voice and data transmissions. The range for connectivity is less than 10 meters, and line of sight is not required. The Bluetooth radio unit can functions even in noisy radio environments, ensuring audible voice transmissions in severe conditions. It can protect data by using error-correction methods and provides a high transmission rate. It is possible encryption and authentication for privacy in the transmitted data.

In Bluetooth ad hoc networking enables personal devices to automatically exchange information and synchronize with each other.
