Bluetooth is defined as layered protocol architecture because each layer supports the layer above and below it.  The complete protocol stack consists[[wysiwyg_imageupload::]] of both Bluetooth specific protocols which are clearly defined or developed for Bluetooth like LMP and non-Bluetooth specific that were designed to enable the re-use of existing protocols for various functions. Non-specific protocols can be used with many other platforms like WAP, UDP AND OBEX.

With increasing technology, Automation has become a need whether it is home, office or some other place. At home we come across many appliances be it Fan, AC, TV, Lights, etc. What if you could operate all of them with the Android Phone you’re holding in your Hand..!!This Project aims to incorporate android phone control over electrical appliances. We use Bluetooth communication between Android phone and a Receiver (control unit) that is connected to the appliances. 

Imagine your music player that play for you, a player that sense the ambient LIGHT, TEMPERATURE and TIME that affects the mood of a person, and pick a song categorize as MOODs. Because I don’t have a sensor that can translate human emotion or thinking to numerical data, I assume that an environment surrounding humans can affect our emotion and which is readable as an analog data using sensors, and because time can easily affect the environment basic traits like light intensity and temperature, I found it as a good solutions for this project. The sensors I used are not enough to consider the exact environment situation; we can still add humidity and sound.

I had been working on a project to make a bluetooth controlled car which is being operated from an Android phone.The basic objective of this project is to make a gaming vehicle which would be controlled by tilting the mobile phone such that the user controls its acceleration as well as directions.The motivation behind my project came basically from the inquisition of Controlling cars using accelerometer in mobile games and PC games.Also we wanted to make such a device which could go into the areas where humans cannot go.Also on seeing many cars used by snake catchers to get the look inside of the snake holesI thought this would be a great idea as the remotes use cell batteries which are not available always but one carry his mobile everywhere. 

Monitoring temperature of a particular place directly is difficult and sometimes impossible (ex: places where humans cannot be). So there is a necessity for wireless monitoring system which enables the user to track the temperature from a remote location. In this article we’ll learn how to build a wireless temperature indicator which sends the temperature value to a PC/Laptop through Bluetooth. The Temperature sensor LM35 produces an output voltage which is directly proportional to its surrounding temperature. For every 1°C of rise/fall in temperature, the output voltage of the sensor varies by 10mV. The output of this sensor is analog in nature which needs to be converted into a digital value using an Analog to Digital Converter (ADC) so it is fed into 37th pin of PORT A of the ATmega16 microcontroller. ATmega16 consists of 8 channels ADC (PA0-PA7) with a maximum resolution of 10 bits. 

In the previous tutorial I have explained how to setup a basic serial connection between an Atmega16 controller Board and a computer/laptop. In this article we’ll learn how to control a robot using the computer/laptop wirelessly through Bluetooth. Let us start with the hardware assembly part first. It should be simple since we are using a ready-made chassis. Start by attaching the motors and castor wheel to the chassis. The components needed for the project are : Atmega16 development board with 16MHz crystal, Serial Bluetooth Module(AUBTM/HC-05/HC-04/BLUSMIRF), PC/Laptop running Windows XP/7/8, USB Bluetooth(Not required if you laptop/PC has inbuilt hardware), Motor Driver L293D, 2 X 12V 100RPM Geared DC motors, 2 X Wheels, Chassis, Castor wheel, Female jumper wires. Keep on reading to find out how the robot is constructed and what coding does it use to operate. 

This project would give you a general idea about how to setup and interface any Bluetooth modem with your computer. There are many types of Bluetooth modems available in market, which vary in quality, cost, range, etc. Some of the well known Serial Bluetooth modems are AUBTM, BLUESMIRF, RN-41, HC-05 and HC-04.I would be using the last one i.e. the cheap Chinese Bluetooth module. It has limited functions and it can only work in slave mode. (Remember: Two slave modules cannot directly communicate to each other so be careful when you buy them.) The top range modules have a facility to work in both MASTER and SLAVE modes. It is Class 3 module so it range is very low. (Class 2 has a range of 10 meters and Class 1 has a range of 100 meters.)
