Hi @osioli,
You can upload to the core first this code (I'm using the Gray core):
#include <M5Stack.h>
HardwareSerial GPS(2);
void setup() {
GPS.begin(9600);
Serial.begin(115200);
}
void loop() {
for (;;) {
if (GPS.available() > 0)
Serial.write(GPS.read());
if (Serial.available() > 0)
GPS.write(Serial.read());
}
}
In u-center set the baud rate to 115200. Go to View-Messages View (F9), expand UBX-CFG-MSG and check UART1.
In my case the satellites detection only works outdoors.
