An overview of bluetooth technology, focusing on its communication topologies (piconet and scatternet), work design, and graphical user interface implementation using matlab. Topics such as data rates, piconet topology, master and slave roles, scatternet, authentication, and time slot allocation. It also discusses the use of matlab's gui designer and various gui objects like push buttons, edit texts, static texts, list boxes, axes, and panels.

Bluetooth is an open RF (radio frequency) wireless standard used for exchange of data over short distances, designed for low power consumption.
A Special Interest Group (SIG) was formed in 1998 to create a standard for this technology.
Different versions of Bluetooth has been released and the BT v3.0 + HS is the latest version in the Bluetooth evolution.
Providing higher data rate upto 24Mbps.

Matlab GUI has been used for the implementation of this project.
Using GUI makes things simpler for the end user.
On the other hand, use of command line interface can be quite difficult and frustrating.
Object: Push Button
Object: Static Text
Object: List Box
Object: Panel
Following is the definitions of the major variables, we have used in this code.
num : This variable represents the current number of nodes in the network and assumes the value 1, when ‘Start Simulation’ is pressed.
IPs_Stack: This is a 2d array that contains IPs. These are randomly choosen IPs that are assigned to the new devices that connect to the piconet as slaves.
status: This variable is a string that contains the current status message string to be shown in ‘edit 1 ’ text box.
nodes: It is a structure array that contains the device name, IP address and pincode of each node present in the network. The fields are assigned the following names:
Device_Name IP Pincode
