Problem in Arduino DUE Serial port communication

Hardware Arduino Due
#1

Hello All,

Recently I bought Arduino Due. I have connected by GPS device via serial. But while reading data i am getting 0xFF from Due board (very frequently).

Already i posted here.
http://arduino.stackexchange.com/questions/18889/arduino-due-getting-0xff-garbage-from-serial?noredirect=1#comment35171_18889

This is sample data received from Due:
5 2 E8 62 16 38 18 0 0 76 F 0 0 14 FC FF FF 0 0 0 0 0 0 0 0 9 0 99 1C

But i am sure that GPS device is working correctly.

Can anyone help on this?

Thanks,
Hari

Can anyone help on this?

Without seeing your code? No.

Herewith i have attached my code.

void setup()
{

Serial.begin(115200); // serial to pc
Serial2.begin (115200); // GPS
Serial.println("init");

}
void loop()
{
while (Serial2.available () > 0)
{
processIncomingByte (Serial2.read (),timestamp,north,east,latitude,longitude, newdata);
}
}

void processIncomingByte (const byte inByte,long& timestamp,double& north, double& east,double& latitude,double& longitude, int&newdata)
{

Serial.println(inByte , HEX);

//Processing message - code
}

What does it look like if you print the characters? It looks to me like the baud rate for the GPS is wrong. Are you sure it is 115200?

What GPS module do you have and at what voltage level is it powered?
