Hi everyone
I know that this topic has been discussed earlier but i've one confusion regarding sending and receiving message thats why i've created a separate topic for that.
I know all the AT commands and i know serial communication too. i've communicated GMS module with hyperterminal and its working correctly but the main problem is im unable to do this through micronctroller(AT 89C51) and im unable to understand the problem behind that. So kindly help me on that.
I've tried AT commands on hyperterminal and all are working fine. and I've checked my microcontroller circuit too and its also fine. But still when i burn the code in microcontroller, its not working at all
Im using SIM 900 module for interfacing
I've used a small code that when i send a message to a number that i've used in coding it has to reply me back after receiving it. but it never happens.
