i am doing a project with gsm modem interfaced with ARM. and i my interface of gsm and muc is not working. i am using simcom gsm.and LPC2129/2368 microcontroller i am getting the GSM data through UART1 interrupt. please give me the connection details i.e. RS232 between the two and the UART1 settings
interfacing is done through UART controller by setting its baudrate to the GSM baud rate. and give the corresponding GSM send command from the micro controller + the number and message as we do in PC .
