Hi Vruti
This is related ot your GSM query. Try out these commands:
"AT+CMGF=1rn"
then wait for "OK" response, after this send
"AT+CMGS="write mobile number here"rn"
then wait for ">" response. Write down your message now:
"text message here"
and again wait for ">"; after getting it simply pass a Ctrl-z like this:
"rn"
and if the message is transferred successfully, you will get an "OK" response
This is how you send a msg through GSM module. Hope this was helpful
