%% Bluetooth Personal Area Network:
% This code implements the piconet (communication topology) of the
Bluetooth
% Personal Area Network.
%% Working Design:
% The basic operation of this topology is defined in the following
% steps:
% => One device (Master) is selected to assume the role of the
controller during wireless PAN initialization, and this controller device
mediates communication within the WPAN.
% => A master in a piconet can have 7 slaves at the utmost.
% => The controller broadcasts a beacon that lets all devices
synchronize with each other and allocates time slots for the devices.
% => Each device attempts to join the wireless PAN by requesting a
time slot from the controller.
% => The controller authenticates the devices and assigns time
slots for each device to transmit data.
% => The data may be sent to the entire wireless PAN using the
wireless PAN destination address, or it may be directed to a particular
device.
% => Another important feature is the ability of each device to
lock out other devices selectively, preventing needless interference or
unauthorized access to information.
%% Initialization of Master Node:
num = 0; % Initially there are no nodes in the piconet:
% The connection will be initialized using Matlab GUI, which sets:
num = 1; % Showing the first node, which acts as a master
IP = '127.13.23.1'; % This IP will be entered by the user using the
GUI
% node(IP,num)
m = 'The master node has been initialized'
