Hi !
I have an Modul GPS GY-NEO6MV2 conected tu an ARDUINO UNO board and I have no red coor blink or blue.In the serial monitor appear mesage like"No GPS detected:check wiring" ! I'm near the window !For a 45 min it blinked a blue ,but afther that ...nothing... What can I do?
Since no characters are detected, you do not have the GPS device connected properly. The Installation page for my NeoGPS has suggestions for choosing the best way to connect your device with your Arduino. The Troubleshooting page library also has many suggestions.
Try a simple echo test to make sure the GPS is connected correctly:
//#define gpsPort Serial // one way
#include <AltSoftSerial.h> // another way
AltSoftSerial gpsPort; // on pins 8 & 9 (on an UNO)
//#include <NeoSWSerial.h> // another way
//NeoSWSerial gpsPort( 3, 4 );
void setup()
{
Serial.begin( 9600 );
gpsPort.begin( 9600 );
}
void loop()
{
if (gpsPort.available()) {
char c = gpsPort.read();
Serial.write( c );
}
}
You should see lines of text starting with $GPGGA, $GPRMC, $GPGSV and others.
If you don't see any output, it is not connected properly. Remember, the GPS TX pin should be connected to the Arduino receive pin. That depends on which serial port or library you are using.
