Hello.
I have been trying to create a serial link between the Launchpad (based on tm4c123gh6pm) and my cellphone. The code is very simple for testing purpose. Here is it:
/* This is a demo code for testing Bluetooth functionality
->The peripheral used here was a smartphone; and to obtain the values of 'i' on the terminal of the device, the "display mode" setting must be changed to ' HEX'
->The code doesn't work properly on when the pin 10 and 11 are used as RX and TX
->It has been successfully tested to send the values of i to the Rx terminal and receive the characters sent from there. */
int i=0;
void setup()
{
Serial.begin(9600);
Serial.print("Welcome ");
}
char data_from_Blue=0;
//String rx_str = "";
void loop()
{
for(i=0;i<10;i++)
{
if(Serial.available()>0)
{
data_from_Blue = Serial.read(); // reading the data received from the bluetooth module/the peripheral (phone here)
Serial.println("I received: ");
Serial.println(data_from_Blue);
//Serial.println(rx_str); //display it on serial monitor i.e,the reading has been received here!!
}
Serial.write(i); //Print incrementing value of 'i' across the other terminal(i.e, my cellphone)
delay(1000);
}
}
The code works fine for Arduino+HC05 and MSP430G2 Lauchpad Kit+HC05.
But for TIVA Launchpad mentioned above, the serial monitor simply displays garbled values with '?' within boxes. I have tried almost everything.
Please help me.
