can somebody help me solve this?
i need get text into string from serial read.
getdata1=Serial1.readString(); /// working the variable contains text
then how to do something like this
String getdata1 = (getdata1 && "!OK"); // I need attach after readed text from serial next text
if I resend it as this Serial2.println(getdata1 && "!OK"); I will receive 1 not the text.
How can I get text from the variable getdata1 readed from serial and combine it with another text, then resend it as Ascii text to another serial port?
