What is Bluetooth protocol?

Bluetooth is a standardized protocol for sending and receiving data via a 2.4GHz wireless link. It’s a secure protocol, and it’s perfect for short-range, low-power, low-cost, wireless transmissions between electronic devices. Or, with the right module, it can be used to build a homebrew, wireless MP3-playing speaker.

What are the different Bluetooth protocols?

The commonly adopted protocols used in Bluetooth are Point-to-Point Protocol (PPP), Internet Protocol (IP), User Datagram Protocol (UDP), Transmission Control Protocol (TCP), and Wireless Application Protocol (WAP). AT Commands − ATtention command set.

Is Bluetooth an IEEE standard?

Bluetooth is a standard for short range, low power, and low cost wireless communication that uses radio technology. The wireless personal area network (WPAN) technology, based on the Bluetooth specification, is now an IEEE standard under the denomination of 802.15 WPANs.

What is SCO and eSCO?

SCO data is symmetric, full-duplex, and fixed at 64 kbits/s. Using eSCO will add two multislot packet types and allow for asymmetric data rates. In fact, no data needs to be transmitted at all.

What is architecture of Bluetooth?

Bluetooth is both a hardware-based radio system and a software stack that specifies the linkages between the architecture layers of the two. Bluetooth protocol stack consists of a three-layer hardware lower stack (radio, Baseband, LMP), and a three-layer software upper stack (HCI, L2CAP, and SDP).

What are the components of Bluetooth architecture and discuss its protocol stack?

Bluetooth protocol stack:

  • Radio (RF) layer: It performs modulation/demodulation of the data into RF signals.
  • Baseband Link layer: It performs the connection establishment within a piconet.
  • Link Manager protocol layer:
  • Logical Link Control and Adaption protocol layer:
  • SDP layer:
  • RF comm layer:
  • OBEX:
  • WAP:

Where is Bluetooth protocol used?

Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances using UHF radio waves in the ISM bands, from 2.402 GHz to 2.48 GHz, and building personal area networks (PANs).

Which country invented Bluetooth?

History. The development of the “short-link” radio technology, later named Bluetooth, was initiated in 1989 by Nils Rydbeck, CTO at Ericsson Mobile in Lund, Sweden.

Is Zigbee efficient than Bluetooth?

the frequency range supported in Zigbee mostly 2.4 GHz worldwide, it means 2.4 GHz is not supported all times. It covers more distance as compared with Bluetooth. In above figure, we can see that the data transfer rate is faster in Bluetooth than zigbee whereas zigbee covers larger distance than Bluetooth.

What is SCO Bluetooth?

SCO (Synchronous Connection Oriented Link) This is a voice data link. While Bluetooth is the technology used to connect devices from different manufacturers without wires, the devices still have to talk to each other while providing what ever service they are designed for.

What is a Bluetooth protocol stack?

The Bluetooth protocol stack is a set of layered programs. Each layer in a protocol stack talks to the layer above it and to the layer below it. Bluetooth protocol stack consists of a three-layer hardware lower stack (radio, Baseband, LMP), and a three-layer software upper stack (HCI, L2CAP, and SDP).

What is the architecture of Bluetooth?

The Bluetooth architecture has its own independent model with a stack of protocols, instead of following the standard OSI model or TCP/IP model. The protocols in the Bluetooth standard can be loosely grouped into the physical layer, data link layer, middleware layer, and application layer as shown in the following diagram −

What are Bluetooth protocols?

The wireless data exchange standard Bluetooth uses a variety of protocols. Core protocols are defined by the trade organization Bluetooth SIG. Additional protocols have been adopted from other standards bodies.

What are the physical layer equivalent Protocols of Bluetooth?

Physical Layer − This includes Bluetooth radio and Baseband (also in the data link layer. Radio − This is a physical layer equivalent protocol that lays down the physical structure and specifications for transmission of radio waves. It defines air interface, frequency bands, frequency hopping specifications, and modulation techniques.
