Serial Monitor does not work #2772
Description
Describe the problem
using serial monitor to show variables etc does not work i.e.
input string to serial input with the code below should give output on serial monitor, it outputs nothing
I tested this using Arduino 1.8.19 ----- works perfectly
then with Arduino 2.3.6 ------ no output to serial window
To reproduce
note !! return character set to carriage return for this to work
void setup() {
Serial.begin(115200);
while(!Serial);
Serial.println("Serial started");
}
String kbdInput = "";
bool inptrdy = false;
//-------------------
void loop() {
if(Serial.available()) {
char c = Serial.read();
if(c != 13) {
kbdInput += c; // add c to string
}
else inptrdy = true;
Serial.print("serial ok c: ");
Serial.println(c);
Serial.println("kbdInput: " + kbdInput);
Serial.println("inputrdy: " + inptrdy);
}
if(inptrdy) {
Serial.println("inptrdy true kbdInput: " + kbdInput);
if(kbdInput == "c") {
Serial.println("Keyboard commands:");
}
else if(kbdInput == "tables") { // print tables
Serial.println("printTheTables()");
}
else if(kbdInput == "restart") { // restart node
Serial.println("Power On Reset this node");
}
kbdInput = "";
inptrdy = false;
}
}Expected behavior
the code above should give output in the serial window when prompted with serial input followed by return
