gpsd4j's Issues

ErrorMessage cannot be resolved to a type

Hi,

I have downloaded and imported gpsd4j into Eclipse IDE and I got two errors:

  1. ErrorMessage cannot be resolved to a type
  2. WatchMessage cannot be resolved to a type

Both in GpsdClient.java file.

Any hints on how to solve it, please?

Thanks and Happy New Year 2021 :)

Fails to parse some messages when too much data

Hi,

Firstly, thank you for this library. It's really useful.

I have been testing it with the gpsfake and I have run into a problem. If I send messages only as fast as I can hit enter in gpsfake (using -i argument), everything is fine, but if I let it run on its own (without -i argument), it floods the socket with messages, then the library tries to parse half of the message only, which fails, which in turn sometimes causes it to disconnect and connect again.

This how I configured the GpsdClient:

gpsdClient.addErrorHandler(errorMessage -> logger.e("Jarek", errorMessage.getMessage()));

gpsdClient.addHandler(TPVReport.class, tpv -> {
    Double latitude = tpv.getLatitude();
    Double longitude = tpv.getLongitude();
    if (latitude == null || longitude == null) {
        return; // if gpsd daemon gets restarted, library reconnects but returns one TPV event with no coordinates
    }
    logger.i("Jarek", "latitude: " + latitude + ", longitude: " + longitude);
});

gpsdClient.addHandler(ATTReport.class,          x -> logger.i("Jarek", "ATTReport: "          + x.toString()));
gpsdClient.addHandler(GSTReport.class,          x -> logger.i("Jarek", "GSTReport: "          + x.toString()));
//gpsdClient.addHandler(SKYReport.class,          x -> logger.i("Jarek", "SKYReport: "          + x.toString()));
gpsdClient.addHandler(TOFFReport.class,         x -> logger.i("Jarek", "TOFFReport: "         + x.toString()));
gpsdClient.addHandler(DeviceMessage.class,      x -> logger.i("Jarek", "DeviceMessage: "      + x.toString()));
gpsdClient.addHandler(DevicesMessage.class,     x -> logger.i("Jarek", "DevicesMessage: "     + x.toString()));
gpsdClient.addHandler(ErrorMessage.class,       x -> logger.i("Jarek", "ErrorMessage: "       + x.toString()));
gpsdClient.addHandler(GpsdCommandMessage.class, x -> logger.i("Jarek", "GpsdCommandMessage: " + x.toString()));
//gpsdClient.addHandler(GpsdMessage.class,        x -> logger.i("Jarek", "GpsdMessage: "        + x.toString()));
gpsdClient.addHandler(PollMessage.class,        x -> logger.i("Jarek", "PollMessage: "        + x.toString()));
gpsdClient.addHandler(VersionMessage.class,     x -> logger.i("Jarek", "VersionMessage: "     + x.toString()));
gpsdClient.addHandler(WatchMessage.class,       x -> logger.i("Jarek", "WatchMessage: "       + x.toString()));

gpsdClient.setSuccessfulConnectionHandler(client -> {
    logger.i("Jarek", "Successful connection!!!");
    client.watch();
});

gpsdClient.start();

Here are all the logs in ~0.5s window of time:

But they are in fact a single object.

Then it continued and parsed a few more messages. And then it tried to parse half of the message again at 2020-02-10T11:40:34.093Z, which caused a disconnect.

Have I configured something wrong? Any help would be appreciated.

Best wishes,
Jarek
