DK-TM4C-123G and HC-06 Bluetooth module Communication

Dear experts, I am actually the first time to use Ti development board. I have a little bit Arduino Programming background. Previously , I have used Arduino Uno + HC-06 Bluetooth to set up communication with Android in Smartphones with the following coding:
----------------------------------------------------------------------------------------------------------------------------------------------------
/*
  Sends sensor data to Arduino
  (needs SensorGraph and Amarino app installed and running on Android)
*/
 
#include <MeetAndroid.h>

MeetAndroid meetAndroid;

float temp;
void setup()  
{
  // use the baud rate your bluetooth module is configured to
  // not all baud rates are working well, i.e. ATMEGA168 works best with 57600
  Serial.begin(115200);
 

}

void loop()
{
  double C1 = analogRead(A0);
 
  int vol =5*1000 - C1*1000*5/1024;
 
 
 
  if (vol == temp)
  { temp == vol;
  }
  else
  {

  meetAndroid.receive(); // you need to keep this in your loop() to receive events
 
  // read input pin and send result to Android
  meetAndroid.send(vol);
 
  // add a little delay otherwise the phone is pretty busy
  delay(300);
  }
----------------------------------------------------------------------------------------------------------------------------------------

May I ask if I could do the same procedure on DK-TM4C123G ? And the how about the hardware TX RX pin connection? Because I am very new to Ti, may I ask could I direct use the same code on Energia ? I have tried this by connecting the HC-06 TX and RX to U3RX and U3TX respectively. However, gibberish is record by the serial monitor.
