This device acts as interface between your microcontroller project and a GSM phone. It handles all modem data communication between the GSM phone and your micro-project. The best thing is that it decodes PDU into TEXT on the fly! You can easily SMS-enable your any project without need for learning AT commands and parsing complicated data when talking to AT modem inside the phone.
Thanks for reply,i know how to check.For checking at commands,instead of using microcontroller can i use Pc rs 232 to connect with mobile pinouts. That means connection is
PC-TX->Mobile-Rx,
PC-RX->Mobile-TX,
common gnd.
It will work?, if true means how can i get the received command in pc.
Thanks i tried the link which u gave, it is working, i found that my modem was working in text mode. but i want to interface microcontroller with mobile pinout through RS 232. Before i tried the command through COM port in pc not through data cable, not working connection is tx,rx, gnd of pc to tx,rx,gnd of mobile pinout. i tested the command through hyper terminal. Otherwise i have to use Mbuss pin
