Is it possible to serial print the sign " ?
I need to use that sign in AT command but clearly not possible if i try with:
Serial.println("AT+CPMS="ME"");
When included in a string literal, a backslash means the next character is special.
Serial.println("AT+CPMS=[glow]\[/glow]"ME[glow]\[/glow]"");
' for a single quote
" for a double quote
\ for a single backslash
\0 for a zero byte
\xFF for a byte with hex value 0xFF
\277 for a byte with octal value o277
\n for a newline
\t for a tab character
There's about ten others I'm too lazy to look up at the moment. They're called escape sequences. Only some of these are supported within character literals (those single-character strings in single quotes).
Thanks a lot, it works!
Think that information should be added to the arduino reference area.
Yes, maybe it probably should be in the reference area. However, for some reason the Arduino site doesn't really call much attention to the fact that the language is just a plain vanilla world-wide standard C++. Perhaps to admit that fact would intimidate a lot of newcomers who have heard that C++ is hard or something. Anyway, to really learn the language of Arduino development, you have a lot of good resources on C++ already out there, maybe even in your local bookstore.
