Hi everyone!
Im using an ESP32 with a Neo M8N GPS and the TinyGPS++ library.
When I connect my NEO M8N via USB to u-centre, u-centre reports ~10 GPS satellites, and a further 9 or so BeiDou satellites, for a total of ~19 satellites.
However when the M8N is connect to the ESP32 (and the tiny GPS++ library) , gps.satellites.value() will only ever report/phrase a max of 12 satellites.
How exactly do I get tinyGPS++ to calculate all the satellites that u-center sees?
Ideally Id like tinyGPS++ to:
1/ Report the (real) total number of satellites.
2/ Report the number of GPS satellites.
3/ Report the number of BeiDou satellites.
4/ Report the 2D accuracy in meters.
5/ Report the heading in deg.
Ive had a look at TinyGPS++ : UsingCustomFields can extract custom
fields from any NMEA sentence.
https://codebender.cc/example/TinyGPS++/UsingCustomFields#UsingCustomFields.ino
But dont understand How to convert the M8N output to NMEA, and what tinyGPS++ custom fields I need for 1-5 (above^^)
Here is my code (forgive me, its a real hack)
#include <Wire.h>
#include <TinyGPS++.h>
#include <SPI.h>
#include <TFT_eSPI.h>
TFT_eSPI tft = TFT_eSPI();
#define RXD2 16
#define TXD2 17
HardwareSerial neogps(1);
TinyGPSPlus gps;
void setup() {
tft.init();
tft.setRotation(1);
Serial.begin(115200);
//Begin serial communication Arduino IDE (Serial Monitor)
//Begin serial communication Neo6mGPS
neogps.begin(9600, SERIAL_8N1, RXD2, TXD2);
}
void loop() {
boolean newData = false;
for (unsigned long start = millis(); millis() - start < 1000;)
{
while (neogps.available())
{
if (gps.encode(neogps.read()))
{
newData = true;
}
}
}
//If newData is true
if(newData == true)
{
newData = false;
tft.fillScreen(TFT_BLACK);
tft.setTextColor(TFT_WHITE, TFT_BLACK);
tft.setCursor(2, 2, 4);
tft.print("Knots ");
tft.setCursor(85, 2, 4);
tft.print(gps.speed.kmph()) / 1.852;
tft.setCursor(175, 2, 4);
tft.setTextColor(TFT_WHITE, TFT_BLACK);
tft.print("Satellites ");
tft.setCursor(283, 2, 4);
tft.print(gps.satellites.value());
tft.setTextColor(TFT_WHITE, TFT_BLACK);
tft.setCursor(2, 42, 4);
tft.print("Longitude ");
tft.setCursor(25, 80, 6);
tft.print(gps.location.lng(),5);
tft.setTextColor(TFT_WHITE, TFT_BLACK);
tft.setCursor(2, 143, 4);
tft.print("Latitude ");
tft.setCursor(25, 180, 6);
tft.print(gps.location.lat(),5);
Serial.print("Satellites ");
Serial.println(gps.satellites.value());
Serial.print("Lat ");
Serial.println(gps.location.lat(),5);
Serial.print("Lng ");
Serial.println(gps.location.lng(),5);
Serial.print("Speed KMPH ");
Serial.println(gps.speed.kmph());
//print_speed();
}
else
{
}
}
