industrial devices control using bluetooth module ppt

Abstract:

The main aim of this project is to control the electrical appliances in industry like machines, motors, etc using Bluetooth module.These Bluetooth modules are more reliable, secure and low power modules and these modules do not require line of sight also. We can use mobile Bluetooth by developing some applications or we can use normal USB blue tooth dongles by connecting to PC.Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavel ....etc

I am using UART for communicating 8 modules having LPC2148 microcontroller as a slave with another module having LPC2148 as master.But I am finding a constraint of wire length(I have read some articles on net which suggest a wire length of 2.6 mtrs for a baudrate of 56000bps) Can I replace this with MODBUS communication ?If yes where can I get information about modbus? ....etc

I am doing a project on industrial devices control using bluetooth.For this i have to give a one power point presentation. I am having some matter,but it does not enough
to give ppt.So i request you to give some more information for me.

with kind regards
