[Bluno] Code hang up until serial monitor launch

does someone know why the code hang up until serial monitor launch?
I've bluetooth device to receive the data from arduino.
BLUNO borad is (UNO+Bluetooth Low Engery module).
that's why our code only do serial prints.
Then i expect our app(ble device) can receive those data.
But just like i said,
our app can receive those data until serial monitor launch.
Here is the source code.
Any suggestions are appreciated.

Code: Select all
#define BAUD_RATE_BLE 9600
void setup() {
// put your setup code here, to run once:
Serial.begin( BAUD_RATE_BLE); // bt
delay(2000);
}
void loop() {
// put your main code here, to run repeatedly:
Serial.print("loop");
delay(2000);
}
Any suggestions are appreciated.
