post how you have configured your serial monitor
what line-ending?
what did you really type into the send-field
write it again into the send-field of the serial monitor mark copy & paste into a code-section of a posting

add serial printing of what you send to BTserial

if (Serial.available())
    {
        c = Serial.read();
 
        // do not send line end characters to the HM-10
        if (c!=10 & c!=13 ) 
        {  
             BTserial.write(c);
             Serial.print(c);
        }

to echo what was received

put what you want to print to BTSerial into a variable
so you can again send the exact same content to BTSerial and to Serial

char myCommand[] = "Exit";
BTserial.print(myCommand); // prints to app on phone
Serial.print(myCommand);
