Hi....
I need to send some AT commands along with a message, to send an sms, to a GSM modem through a micro controller as a part of my BE project. I dont have much knowledge of a GSM modem. Which one should I use...?
I know that uc and the modem are interfaced through a serial port but how do i send the command and what are the actual connections......???
