MSP430F5529: MSP430F5529

Part Number:MSP430F5529

Hello,

I have been working with the MSP4305229 Launchpad and have been trying to work with Bluetooth. I am using a RN 42X module and have it powered up, and connected. My issue though is at least getting a signal from the MSP430s TXD pin. I am using energia because the information I need to send is not to complex, and from my understanding, using 

Serial.print();   Serial.println();   should be giving a signal to the TXD pin at least. I have used a scope though, and as soon as I power on the launchpad, the TXD goes high and stays there without transmitting my signal. My code I am using is below.

#include <stdint.h>

void setup() {
//set baud rate to match BT module
Serial.begin(115200); 
}

void loop() {
{

String t; //string to hold data from BT module

// while(Serial.available()) { //keep reading bytes while they are still more in the buffer
// t += (char)Serial.read(); //read byte, convert to char, and append it to string
// }

if(Serial.available()) { //keep reading bytes while they are still more in the buffer
t += (char)Serial.read(); //read byte, convert to char, and append it to string
}

while(t.length()) { //if string is not empty do the following

Serial.print("Should Not Be Recieving Data!!!\n"); //send this for any other string
}

delay(2000);
Serial.println(0);

Serial.println(1);

Serial.println(5);

}

}}

I have tried both with and without the jumper to the EZ FET board, but to no avail. 

Am I missing something? Should Serial.println not be sending a signal to the TXD pin?

Thank you for any help or information
