makefile not working with tinyGPS and tinyGPSPlus

[kamze]

I am trying to compile an example of tinyGPSPlus (same goes tinyGPS) for it works fine when i compile it using arduino IDE but when i use make upload there is no error but i don't receive any GPS data. Please note that i have all ready uploaded functional programs using make upload. Could it because of the baudrate mismatch talked about here :https://github.com/ladislas/Bare-Arduino-Project/issues/45

can you try printing something else right before the GPS data. it will help us figure out if it the printing that doesn't work or just the data.

so the code is :

#include <TinyGPSPlus.h>
#include <SoftwareSerial.h>
/*
   This sample sketch demonstrates the normal use of a TinyGPS++ (TinyGPSPlus) object.
   It requires the use of SoftwareSerial, and assumes that you have a
   4800-baud serial GPS device hooked up on pins 4(rx) and 3(tx).
*/
static const int RXPin = 3, TXPin = 2;
static const uint32_t GPSBaud = 4800;

// The TinyGPS++ object
TinyGPSPlus gps;

// The serial connection to the GPS device
SoftwareSerial ss(RXPin, TXPin);

void setup()
{
  ss.begin(GPSBaud);
  Serial.begin(9600);
}

void loop()
{
  Serial.println("-----------Test---------- ");

  while (ss.available() > 0)
    if (gps.encode(ss.read()))
      if (gps.location.isValid())
  {
    Serial.print("Location: ");
    Serial.print(gps.location.lat(), 6);
    Serial.print(",");
    Serial.println(gps.location.lng(), 6);
  }

}

using arduino's IDE with 9600 baud i get this :

----------Test---------- 
-----------Test---------- 
-----------Test---------- 
-----------Test---------- 
-----------Test---------- 
Location: 48.299602,4.064558
-----------Test---------- 
-----------Test---------- 
Location: 48.299602,4.064558

Location: 48.299602,4.064558
-----------Test---------- 
-----------Test---------- 
-----------Test---------- 
Location: 48.299602,4.064558

but using make upload on 4800 (i didn't change the code at all if put 9600 baud i get these weird caracters) i get this : 
-----------Test---------- 
-----------Test---------- 
-----------Test---------- 
-----------Test---------- 
-----------Test----------

i set GPSBaud to 9600 and it worked but i dont know why

[ladislas]

the baudrate in the makefile is only to use make monitor and must be set to the same value as Serial.begin(9600);

The GPS baudrate might be something else, I don't know what it is.

closing this issue as it is out side of the scope of this repo

ok thank you
