GPS MTK 3329 Arduino

Post by Coraz97 »

What I'm trying to do is to read my position (NMEA) connecting the MTK 3329, bought with a MultiWii PRO from HobbyKing, to an Arduino UNO, but I'm getting only random ASCII characters.

Connections:

Arduino - MTK 3329

5V - Vcc
GND - GND
Pin 0 (Rx) - Tx
The GPS receiver shouldn't be receiving anything so I didn't connect it.

That's one of the sketches I used:

Code: Select all

void setup() {
  Serial.begin(4800);
}

void loop() {
  byte b;
  if (Serial.available() > 0) {  //without > 0
    b = Serial.read();
    Serial.write(b);
  }
}


The baud of the Serial monitor is 4800. I tried different rates, but no changes.

The GPS is pointed to the sky, but even if it's been cloudy in these days I still get random characters.

Has anyone got any 'gotchas' I'm missing?
