Combining UbxGpsNavPvt and SoftwareSerial

[mkschneider]

Many thanks for your great instruction on using u-blox modules with arduino. However, I am a real beginner with arduino programming, so pardon my stupid question. I have connected a CAM-M8Q to an Arduino Uno and am able to monitor UBX binary code on the serial monitor. However, I could not figure out how to feed this into UbxGpsNavPvt to convert it. The line UbxGpsNavPvt gps(ss); (code below is throwing me: no matching function for call to 'UbxGpsNavPvt::UbxGpsNavPvt(SoftwareSerial&)'

Many thanks for any advice

#define PC_BAUDRATE     9600
#define GPS_BAUDRATE    9600
#define GPS_RX          3
#define GPS_TX          2
#define DATETIME_FORMAT "%04d.%02d.%02d %02d:%02d:%02d"
#define DATETIME_LENGTH 20

#include "UbxGpsNavPvt.h"
#include "SoftwareSerial.h"

SoftwareSerial ss(GPS_TX, GPS_RX);
UbxGpsNavPvt gps(ss);

char datetime[DATETIME_LENGTH];

void setup()
{
    Serial.begin(PC_BAUDRATE);
    ss.begin(GPS_BAUDRATE);
}

// If there is a data from the receiver, read it and send to the PC or vice versa
void loop()
{
    if (gps.ready())
    {
        snprintf(datetime, DATETIME_LENGTH, DATETIME_FORMAT, gps.year, gps.month, gps.day, gps.hour, gps.min, gps.sec);

        Serial.print(datetime);
        Serial.print(',');
        Serial.print(gps.lon / 10000000.0, 7);
        Serial.print(',');
        Serial.print(gps.lat / 10000000.0, 7);
        Serial.print(',');
        Serial.print(gps.height / 1000.0, 3);
        Serial.print(',');
        Serial.print(gps.gSpeed * 0.0036, 5);
        Serial.print(',');
        Serial.print(gps.heading / 100000.0, 5);
        Serial.print(',');
        Serial.print(gps.fixType);
        Serial.print(',');
        Serial.println(gps.numSV);
    } else Serial.print('.');
}

Hi, @mkschneider!

I see, the problem is that the UbxGps constructor is waiting for HardwareSerial instance, instead of SoftwareSerial. My bad, I described the problem with SoftwareSerial, but did not test it.

Thank you a lot for your feedback! Just gimme a couple of days and I will update the library. Then I'll wait for your feedback about using the CAM-M8Q, since I haven't tested the library with 8th generation of u-blox modules.

Hi, here I found a workaround.

I need to make some adjustment for my Atmega328p.

See below !

UbxGpsNavPvt gps( (HardwareSerial&) ss); void setup() { gps.begin(GPS_SPEED); ss.begin(GPS_SPEED); // GPS don't sync without this line
}

Next, I had to modify UbxGps.cpp and UbxGpx.h and UbxGpsNavPvt.h (see attachement).
