I have a GPS TinyShield and am running the official example, but I only get this output:

**** **** ********* ********** **** ********** ******** **** ****** ****** ***** ***   *******  ****** ***   17046 0         0       

It does this infinitely. I have it sitting on a window with clear view of the sky for 10 minutes. I'm using this example:

I have a WiFI module which is not working either. 0/2 right now unfortunately for TinyCircuits. I've spent 2 days reading posts trying to solve this, no luck yet.

I bought 2 new TinyProcessor but still not getting any action from TinyGPS. 0 satellites found. The TinyProcessor works with the TinyAccelerometer Rectangular, so I have no reason to believe the processor itself is bad nor my dev setup. I see accelerometer read outs in the monitor. But still no GPS.  I'm testing the TinyGPS independent of other censors. My setup is just the USB unit, processor and TinyGPS.

Just bought the TinyGPS and exactly the same thing.  All results are *** and RX keeps incrementing, but no sentences are ever processes.  1 hr outside with clear line of sight to the sky and not response.

Was there just a batch of bad GPS modules from TinyCircuits or is the same code bad for the ASD2501 (Rev 4)

O.k., the answer to this question is:

static const int RXPin = A1, TXPin = A0;

TinyGPS is located on those pins.   Be sure to leave the hardware as 1,0 as those service the USB to Serial port output.

static const int RXPin = A1, TXPin = A0;
static const uint32_t GPSBaud = 9600;

This solution worked for the "Simple Test" sketch.  I am now able to see location data in the serial monitor after following Pascaljedis advice.
My code for the setup section now loos like this:

"void setup()
{
  // Added this
  static const int RXPin = A1, TXPin = A0;
 
  SerialMonitorInterface.begin(115200);
  ss.begin(GPSBaud);
  while (!SerialMonitorInterface && millis() < 5000); //On TinyScreen+/SAMD21 platform, this will wait until the Serial Monitor is opened or until 5 seconds has passed
 
  SerialMonitorInterface.print("Simple TinyGPS library v. "); SerialMonitorInterface.println(TinyGPS::library_version());
  SerialMonitorInterface.println("by Mikal Hart");
  SerialMonitorInterface.println();
 
  gpsInitPins();
  delay(100);
  SerialMonitorInterface.print("Attempting to wake GPS module.. ");
  gpsOn();
  SerialMonitorInterface.println("done.");
  delay(100);
  while (ss.available())ss.read();
}"



(NOTE: I added this: " static const int RXPin = A1, TXPin = A0;" to beginning of setup routine.  The text between the quotation marks.

I hope this helps.

I also just bought a GPS TinyShield and encountered the same situation. Even though I tried the codes as instructed, the results were not better. Maybe I need to ask a friend who is good at technology to help me.

I am successfully using the GPS Tiny Shield with a TinyZero. These are the relevant lines from my code:

Code Select Expand

...
#include "GPS.h"
#include "SoftwareSerialZero.h"
TinyGPS GPS;
SoftwareSerial swuart( GPS_RXPin, GPS_TXPin );
...

void setup() {
    ...
    // GPS
    swuart.begin( GPSBaud );
    gpsInitPins();
    delay( 100 );   // delay() is EVIL when GPS is in use
    gpsOn();
    delay( 100 );   // delay() is EVIL when GPS is in use
    // Drain the GPS module's pent-up data
    while( swuart.available() )
        swuart.read();
    ...
}

void loop() {
    int year;
    byte month, day, hour, minute, second, hundredths;
    unsigned long age;
    float flat, flon;

    ...
    GPS.crack_datetime( &year, &month, &day, &hour, &minute, &second, &hundredths, &age );
    if( age != TinyGPS::GPS_INVALID_AGE ) {
        ...
    }
    GPS.f_get_position( &flat, &flon, &age );
    if( age != TinyGPS::GPS_INVALID_AGE ) {
        ...
    }
}


I use the GPS in a widget that provides data for astrophotography, including the current GMT and location among other data. It will take 5 to 10 minutes to get a fix when it's first used after a long time. The next night, however, it will get a fix within 30 seconds.
