The growing implementation of technology had significant impact on its methods and practice. One technology with such an impact is the ever growing use of wireless systems in hospitals, industries and biomedical institutions. The objective is to transfer processed real time signal over Bluetooth using PIC Microcontroller. This is applicable for monitoring certain parameters such as temperature, bio-medical signals and more. The system is implemented for real time data, audio and analog signal transfer using Bluetooth communication. PIC microcontroller (PIC16F877A), Audio Codec Board, Bluetooth module (Ezurio Blu2i) and MAX232 level converter are used to build the proposed system. Software design process is carried out using MPLAB IDEv6.50, XC8 compiler and PPPv3 (PICmicro parallel programmer). For Implementation of real time data, PIC microcontroller will initialize the Master Bluetooth module with set of protocols and it transfers real time data to receiver. Slave Bluetooth module will access the real time data using PIC microcontroller receive program. Data is monitored on the Terminal tool using serial interface. For Implementation of audio and analog signal, Audio codec board is connected to both master and slave Bluetooth devices. PIC microcontroller will initialize Bluetooth module and audio codec board both in the transmitter and receiver. Audio mode is enabled and analog signal is transferred between Bluetooth modules by using audio codec board. This project aims to develop a prototype model through which the user can send any real-time signal via Bluetooth communication using PIC16F877A.
