AT Commands to send an SMS Required Hardware: MCU connected to a GSM modem via the UART. MCU Code: printf("AT+CMGF=1\r");// this ensures the GSM modem is in Text Mode //delay around 1 second printf("AT+CMGS="XXXXXXXXX" \r");// XXXXXXXXXX this number is the receipient of the SMS //after the above command, the GSM will send the response ">" to the MCU. //The MCU should await for this character before sending the message as below: printf("This is a sample message");//Send your message here, maximum of 160 characters. putchar(0x1A);// last command to send the message |

Communication with the PC’s serial port (or virtual serial port over USB-Serial converter) may be better viewed on serial emulation software that will transparently display received ASCII data and likewise be able to send data using the keyboard. One of such software is the Hyperterminal. The HyperTerminal is a bundled software that comes with MS Windows OS. This mini-tutorial will show how to quickly set-up the Hyperterminal for your MCU projects: http://www.layadcircuits.com/layad_articles/Hyperterminal_Setup.htm

The objective of this article is to demonstrate the use of the UART that is built-in a microcontroller unit(MCU) in basic applications intended for the novice electronics designer. It shall cover the physical layer design and fundamental software control. In-depth discussion of the data protocol will not be covered. This short article is intended as a practical guide on UART interfacing. Please click on the link below for the main article: http://www.layadcircuits.com/layad_articles/UART_Basics.htm |
