Hi Guys,

I am using LPC1769 UAR3 to communicate with a SIM900 GSM Module. I have successfully configured the GSM using Tera Term (hyper terminal) and I can successfully send and receive SMS while communicating between SIM900 and LPC1769. However, when I key in the command "AT+CCLK?" and Tera Term can return current time back to me. My problem is that how can I get the time information when the GSM Module communicate with LPC1769. My Initialization of UART3 is correct.

char tm[] = "AT+CCLK?\r";

UART_SendString(LPC_UART3, (uint8_t *)tm);
Timer0_Wait(5000);

After I send this command to UART3, How can I get the information which is shown in the picture attached back and printf it in the console?

Thank you guys!

hi,
Maybe you can consider using the RTC on LPC1769 to help you time keeping your embedded applications.
