Hello
I am facing some issue with the GPS shield
the sketch from examples stops here
if (!GPS.begin()) {
Serial.println("Failed to initialize GPS!");
while (1);
}
I am using the board MKR ZERO+GPS shield+128x64 oled display
MKR ZERO+128x64 work properly but when I add the GPS shiled it stops
looking for help
/*
GPS Location
This sketch uses the GPS to determine the location of the board
and prints it to the Serial monitor.
Circuit:
- MKR board
- MKR GPS attached via I2C cable
This example code is in the public domain.
