Using an Android bluetooth terminal to change preset states on 8x8 LED matrixes
Your problem is, that you read from the EEBlue serial interface, but you are just echoing it over Serial and don't do anything with it. The display code is only executed, when the commands come through Serial.

The simplest way is to copy the code in the if(Serial.available()) statement into the if(EEBlue.available()) statement and changing the read to use EEBlue. Of course you should delete the existing EEBlue.read() from this statement.

But that way would mean to have double the code to maintain. It is cleaner to first read data from either serial interface and then process it. Something like this:

if(Serial.available()){
    cmd = Serial.read();
} else if(EEBlue.available()){
    cmd = EEBlue.read();
}

// insert the code to check the cmd variable for the expected values and act accordingly

cmd = 0; // Resetting the cmd to prevent multiple executions of one command
