Plugin developing: Get current GPS position

[alejandroh]

Hello all!
I'm new developing a OpenCPN plugin. I have search for documentation but can't find the way of getting the current GPS position in a plugin. Any help?

Regards!

Hi there, doesn't the "Dashboard" plugin help you with this? Maybe I'm misunderstanding you

I guess I don't understand the issue. Do you have a device to receive GPS data?
Did you look at this page? https://opencpn.org/wiki/dokuwiki/do...rted:gps_setup

Two options that I know of.

Receiving NMEA events in which position, cog, sog etc. are returned.

int YourPlugin::Init(void) {
.....
return WANTS_NMEA_EVENTS;
}
....
void YourPlugin::SetPositionFix(PlugIn_Position_Fix &pfix) {
    double YourLatitude = pfix.Lat; 
    double YourLongitude = pfix.Lon;
}

or parsing NMEA Sentences (In this case using the NMEA183 classes used by OpenCPN)

int YourPlugin::Init(void) {
.....
return WANTS_NMEA_SENTENCES;
}
....
void YourPlugin::SetNMEASentence(wxString &sentence) {
    // Parse the received NMEA 183 sentence
    nmea183 << sentence;
    if (nmea183.PreParse()) {
        if (nmea183.LastSentenceIDReceived == _T("GLL")) {
         ......

Welcome to the world of OpenCPN Plugin development .
