<![CDATA[Help with the GPS module and M5Stack for AWS]]>I have an M5Stack for AWS, and I have a GPS module connected to its port C. What is the index of the HardwareSerial I should use?

I tried from 0 to 6, but I had no luck reading the data.

HardwareSerial GPSRaw(2);

void loop() {
  if (GPSRaw.available())
  {
    int ch = GPSRaw.read();
    Serial.write(ch);
  }
}

Connection

What I am doing wrong?

have a look at the M5Core2 GPS example. M5Core2 UART uses GPIO 13/14 whereas M5Stack uses GPIO 16/17. If GPSRaw.begin() is called w/o parameters then GPIO 16/17 are used by default. Try something like below to change the GPIOs:

GPSRaw.begin(9600, SERIAL_8N1, 13, 14);

BTW: Index 2 is fine.

Thanks
Felix
