Reading status and XY-coordinates from GPS-widget with PyQGIS 3

Question

Is there a way to access the status and the XY-coordinates from a GPS-connection established by the GPS-widget in QGIS 3 via Python?

I want to establish the connection with the widget to have better control of the connection (like changing ports) and status checks, but need the coordinates inside a Python plugin.

This is a good one! There is a panel to view GPS in the menu View- Panels- GPS information. There must be a way to get that info. — Cary H, Dec 21 '18 at 19:17
Seems to be a bigger issue.. even in the QGIS mailinglist I got no reaction to this question. — Firefly, Dec 22 '18 at 09:23
When keeping the map always centered over the current position, it is possible to get the coordinates with canvas = iface.mapCanvas() canvas.center() . — Firefly, Dec 28 '18 at 21:19

Thanks to the comment of @CaryH I found a solution.

For QGIS 2:

QgsGpsConnectionRegistry().instance()

For QGIS 3:

QgsApplication.gpsConnectionRegistry()

So using the following code

connectionRegistry = QgsApplication.gpsConnectionRegistry()
connectionList = connectionRegistry.connectionList()
GPSInfo = connectionList[0].currentGPSInformation()

After that it is possible to access all information of the widget-gps-connection using for example

GPSInfo.elevation
GPSInfo.latitude

All available commands are listed at https://qgis.org/pyqgis/3.2/core/Gps/QgsGpsInformation.html
