Hi

I am very new to this c programming. I would need c programming codes to send AT commands using using MSP430-eZRF2500.

MSP430 is the mirco controller im using to send sms.

thanks in advance.
 

Do you know to use UART on that? If you know UART, you can refer to other microcontroller AT commands and convert it into MSP430. I have AT Command coding but I don't use MSP430.
 

I also have same problem as Yusuf88. I also need to do C programming to send sms from PC to Hp using GPRS Modem and AT Commands. How to do the coding? I have tried AT commands on hyperterminal to send SMS From PC to Hp. It can send and recieve sms . I am using IAR embedded workbench software.
 

Is your problem with the USART itself or with AT-Commands?
If it's with the USART, try to communicate with the computer first. Use the hyperterminal or any similar software and establish a communication between your controller and the computer.
If your problem is with the AT-Commands, I would recommend you to check the manual of the GPRS modem you are using since the syntax of the command can change from one vendor to another.

Hope this helps.
 

I am not sure on how to use UART on that. So can you pls guide me. Now i not sure what is the first step to send SMS from Computer to Handphone using GPRS modem and AT Commands. For my project i have done some coding. My project is on water level sensor The function of it is that one LED will turn on when 10cm the alert mode is active and 7 segment will display 10, and the two LED will turn on when 20cm the warning mode is active and 7 segment will display 20, the last emergency mode will active when the water level reached 30cm, the buzzer will turn on, and the 7 segment will display 30cm. Now Additional to this i want to add in SMS Function for Emergency level which is 30cm. Once the Water level reach 30cm it has to send sms to the higher authority to take action. But now i don't know how and where to add in the SMS Function inside my code. Pls help me asap.
