Dear all

i need to send AT+CMGL="REC UNREAD" though Usart
the problem is symbol " i cannot send it
could anyone show me how to send it?
 

Transmit 61(Decimal) and 0x3D(Hexadecimal) these are the ASCII value of = symbol

Transmit 34(Decimal) and 0x22(Hexadecimal) these are the ASCII value of " symbol

Hope You understand
 
You have to write [\"] if you need to insert ["] in a string
i hope this can solve your problem
just write
SomeUARTTXFuntion("AT+CMGL=\"REC UNREAD\"");
