Arduino with xbee shield + mDot

Hi Andrew!, thanks for the response, I will try to join the TTN, after my "hello world" happens,

I got another question please, will the mDot modem respond with any info when connected on serial monitor? like with an empty sketch can I just issue AT commands from serial monitor?

I also tried with just sending "AT" on the arduino "setup", should I be able to see the response on the serial monitor?

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);

  Serial.print("AT");

}

void loop() {
  // put your main code here, to run repeatedly:

}

So far Im not getting any response, how to print the responses?, Im missing the basic setup

Thanks!
