#Bluetooth protocol stack software

Hence, many applications are being developed to take immediate advantage of the software and hardware.įirstly, the security of any wireless technology is very important.

The protocol re-use is helpful for the legacy applications to work with the Bluetooth technology to measure the smooth operations and interoperability of applications. The main principle is to minimize the reuse of current protocols for different purposes at higher layers as if re-inventing circle once again. The complete protocol stack architecture of Bluetooth is made up of both Bluetooth specific protocols like object exchange protocols (OBEX) and user datagram protocol (UDP). Anyhow, the protocols have many other relationships between the other protocols – for example, some protocols (L2CAP, TCS Binary) use the LMP to control the link manager. It shows the relationship between the protocols that use the services of other protocols when there is a payload to be transferred in the air. The below diagram shows a complete Bluetooth protocol stack. Bluetooth can run the different applications over different protocol stacks, but, each one of these protocol stacks uses the same Bluetooth link and physical layers. In other words, It defines and provides different types of layers and functionalities. The main function of the Bluetooth is a Bluetooth protocol stack in architecture of bluetooth.

For Example: Connecting 1,278 overhead lights in a warehouse to each other to dim and brighten lights automatically based upon activity and personal preferences.

Mesh: Bluetooth as a way of connecting many devices to many others as if in a spider’s web.

For Example: Playing music on smart speakers and simultaneously casting photos to a projector-both using a single iPhone.

Broadcasting: Bluetooth as a means of having one device broadcast information to many devices or vice versa.

For Example, a computer paired with a wireless mouse.

Pair: Bluetooth as a means of pairing two devices.

It also provides emulation of serial ports over the logical link control and adaption protocol(L2CAP). It provides a serial interface with WAP and OBEX. RF comm layer: It is short for Radio Frontend Component.It allows discovering the services available on another Bluetooth-enabled device. SDP layer: It is short for Service Discovery Protocol.It also performs segmentation and multiplexing. It packages the data packets received from upper layers into the form expected by lower layers. It allows the communication between upper and lower layers of the Bluetooth protocol stack. Logical Link Control and Adaption Protocol layer: It is also known as the heart of the Bluetooth protocol stack.Link Manager protocol layer: It performs the management of the already established links which includes authentication and encryption processes. It is responsible for creating the links, monitoring their health, and terminating them gracefully upon command or failure.It performs the connection establishment within a piconet.

Baseband Link layer: The baseband is the digital engine of a Bluetooth system and is equivalent to the MAC sublayer in LANs.

It defines two types of physical links: connection-less and connection-oriented. It defines the physical characteristics of Bluetooth transceivers.

Radio (RF) layer: It performs modulation/demodulation of the data into RF signals.

A station cannot be mastered in two piconets. This type of node is referred to as a bridge node. This kind of node can receive a message from a master in one piconet and deliver the message to its slave in the other piconet where it is acting as a slave. A slave that is present in one piconet can act as master or we can say primary in another piconet.
