Hi friends,
I am trying to send SMS using GSM modem, after i send destination mobile number I am receiving "\r\n> " as a response from modem , after i enter text to message, i terminated it with "0x1A" character, further i am getting response as "\r\n" from the modem but not \r\nOK\r\n. Can anyone tell me the possible error?
for what time i should wait for receiving the ok response?
Please help

@majoka, Thanks for the reply.
While debugging this problem, i found one another problem with getting connected to wireless network,
If i send the AT+CRQ command to ask signal strength, i got the response as "error: operation not allowed", currently i am trying to solve this issue, also i get CREG response as 0,0 so might be i need to do more for establishing the connection with GSM network(The setting is Auto connect by-default).
Please help me more on this.
Thanks for the reply.

All GSM modems are wireless.
Do you have datasheet/brochure of SL8082. i am not finding it.
Before connecting to controller did you checked response on hyper terminal?

Hi,
Which controller are you using?
Test this in your hyper terminal first.
AT+CMGS="9845XXXXX"(ENTER)
>Type your msg here and press ctrl+z to send the msg.

The same thing you implement in your design.
Share your code for more understanding.

putc(34);//char "

putc(13);//enter CR
