Appinventor and bluetooth module send two data

Hello, I am translating translation using Google Translate because my english is bad:
my question is: I'm using the bluetooth module through the appinventor to stream data,
but I'm sending only one data, how do I send two data?
  if(Serial.available()>0){
    char clock = Serial.read();
 //char name = Serial.read();
    delay(100);
  }

Send them separated by a comma ',' and when you read them on the serial port search for the comma to separate them again

Read the documentation for the read() method. Your code will not work when you try to send more than one char for each value.
