Interface Bluetooth with LPC2148 circuit

Posted on Feb 6, 2014

The Interfacing Bluetooth module with LPC2148 program is very simple and straight forward, which send a message to mobiles from LPC2148 Primer Board through Bluetooth module by using UART0. Some delay is occurring when a single data is sent to mobile through UART. C programs are written in Keil software. The baud rate of microcontroller is 9600.

Give +3.3V power supply to LPC2148 Primer Board; connect the 5V adapter with Bluetooth module which is connected with the LPC2148 Primer Board. There are two Bluetooth modules are required. One is connected with LPC2148 Primer Board; other one is connected with PC. First connect the serial cable between LPC2148 Primer board & PC. Then open the Hyper Terminal screen, select which port you are using and set the default settings. Now the screen should show some text messages. If the messages are correctly displayed in Hyper Terminal, then only connect the Bluetooth modules in LPC2148 Primer Board UART0 & PC. If you are not reading any data from UART0, then you just check the jumper connections & just check the serial cable is working. Otherwise you just check the code with debugging mode in Keil.
