Struggle with TinyGPSPlus and GPS TEL0094
Hello,
I am a beginner on Arduino. I am using a GPS TEL0094 pluged on a Adafruit Feather 32u4 RFM95 LoRa Radio. I have my GPS Module which works with the lights (Power light red constantly and green lignht (PPS light) which alternate between On and off every second). This example was used with the library TinyGps and is from there but I think that however it should still work. My pineout is the following.
GPS -> Feather32u4
VCC -> 3.3 V
GND -> GND
RX -> Pin 6
TX -> Pin 5
EN -> Nothing
PPS -> Nothing
Here is my Code
#include <SoftwareSerial.h>
#include <TinyGPS.h>
/* This sample code demonstrates the normal use of a TinyGPS 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).
*/
TinyGPS gps;
SoftwareSerial ss(6, 5);
void setup()
{
Serial.begin(115200);
ss.begin(4800);
Serial.print("Simple TinyGPS library v. "); Serial.println(TinyGPS::library_version());
Serial.println("by Mikal Hart");
Serial.println();
}
void loop()
{
bool newData = false;
unsigned long chars;
unsigned short sentences, failed;
// For one second we parse GPS data and report some key values
for (unsigned long start = millis(); millis() - start < 1000;)
{
while (ss.available())
{
char c = ss.read();
// Serial.write(c); // uncomment this line if you want to see the GPS data flowing
if (gps.encode(c)) // Did a new valid sentence come in?
newData = true;
}
}
if (newData)
{
float flat, flon;
unsigned long age;
gps.f_get_position(&flat, &flon, &age);
Serial.print("LAT=");
Serial.print(flat == TinyGPS::GPS_INVALID_F_ANGLE ? 0.0 : flat, 6);
Serial.print(" LON=");
Serial.print(flon == TinyGPS::GPS_INVALID_F_ANGLE ? 0.0 : flon, 6);
Serial.print(" SAT=");
Serial.print(gps.satellites() == TinyGPS::GPS_INVALID_SATELLITES ? 0 : gps.satellites());
Serial.print(" PREC=");
Serial.print(gps.hdop() == TinyGPS::GPS_INVALID_HDOP ? 0 : gps.hdop());
}
gps.stats(&chars, &sentences, &failed);
Serial.print(" CHARS=");
Serial.print(chars);
Serial.print(" SENTENCES=");
Serial.print(sentences);
Serial.print(" CSUM ERR=");
Serial.println(failed);
if (chars == 0)
Serial.println("** No characters received from GPS: check wiring **");
}Here is my output :
I am aware that the Rx and Tx must be inversed and I took care of that. I know that the GPS needs 30 seconds to start. I am not quite sure of the PPS and EN purpose despite I read the GPS datasheet several times.
Could somoene help me with this issue ?
