[51] sending text message using printf in C51

[hithesh123]

How do I send a text message with quotes using printf?

example: printf(""hello world");

or

Printf("AT+CMGS="+123456789"");

I get syntax error on keil C51.

Try
printf("hello world");

or

Printf("AT+CMGS="+123456789");

I think It would not work both ways. I use to save the string (like AT+CMGS="+123456789") to a variable and use that variable name to print values
Hope this Helps..!

you just have to use null character - "/"

To send the previous messages

printf("\"hello world\"");

printf("AT+CMGS=\"123456789\"");

use this .
Printf("AT+CMGS=\"+123456789\";");
