SIM 300 GSM Module

also...
SIM card takes some time to register... for that i had used delay of 15 sec in my program.. so is der any direct command for checking the SIM card registration???

yes there is command for sim registration to network.

AT+CREG?

response is
+CREG: 0,1 //registered to home network
+CREG: 0,2 //searching for network
+CREG: 0,5 //registered to network in roaming

we are going to read one register from ADE7754 IC and that value we need to send to GSM Module to get that data through sms on mobile..... how should i proceed??? could u plz reply..

first finish reading that register, later i will tell you how to send it not to worry..

We r done with that part.. Now plz suggest me how do i proceed...

Hi,
First try with AT+CMGS="your Phone no." then enter
then you will find > symbol then put your message and then Ctrl-z.
message will be transmitted

We have send the message through microcontroller also.. i m asking somethng else...we are reading one register from ADE7754 IC and that value we need to send to GSM Module to get that data through sms on mobile..... plzz help..

Hi,
whatever value you get from ade7754, first try to make it readable,like try to send it to UART and see if it is readable at hyperterminal,In short you will have to convert the received value from register to ASCII first then you can send it as message.
