Implementation of Audio Streaming System using Bluetooth

Abstract

Bluetooth is one of the most famous short range wireless communication standards. Almost all modern electronic gadgets available in the market are equipped with Bluetooth support. Analog television or the I-pod or simple radio systems are the devices which are yet not equipped with such facilities. If one wants to enjoy Television or Music System at night without disturbing others, one may require to send the sound of Television to the headphones by wire or wireless connectivity. Wired headphones have no mobility and have many limitations. Bluetooth enabled headphones are available in market, but system cannot transmit the audio on Bluetooth. So, the project aim is to design the embedded hardware which enables any analog or digital devices, which are capable of generating analog or digital signals, to send the signals to the audio headset using Bluetooth standards. Audio of Television or Music system can be listent by Bluetooth headsets. Audio Streaming System is implemented using ARM family LPC2148 microcontroller and LMX9838 Chip from Texas Instruments (TI). LMX9838 supports Headset profile (HSP) and Serial Port Profile (SPP). These profile is utilize for Audio Streaming. Two different possible methods for the implementation of the system are discussed in this thesis.
