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
In my code i am getting the gsm data through UART1 interrupt, i am connecting GSM modem to the UART1 port. the modem is working properly with hyperterminal, but not with microcontroller.
When checking, debugging, etc, have you done to find out why it is not working?
