gsm gprs moule problem

[Kingjeffrey]

hello i'm using a sim900D and i'm trying to send a sms through microcontroler
the problem that i was encounter right now is that when i reach the AT+CMGF=1$0D the outcome is error instead of ok..
how can i fixed this please do help me..asap! i'm using a terminal..

For sending sms, the syntax for that is AT+CMGS="xxxxxxxxxxx"<CR><LF> where xxxxxxxxxxx = cell phone number to which you want to send SMS. The hex value for <CR> = 0x0D, and for <LF>=0x0A.

Okay! But i am not able to get you why you want to use AT+CMGF=1$0D?

AT+CMGF=1$0D

Is it correct, i think it is AT+CMGF = 1, where come $?

i think you have some problem in code to sent the command from microcontroller. So, try the following code to sent from microcontroller

AT+CMGF=1,0DH,0AH (where 0DH and 0AH both used for special character (enter))
i think this will help you, if it will not solve your problem then sent me your code.
