I would like to access the device described at QGIS live GPS tracking /recommended hardware (GPS USB stick) via QGIS/Python.

A gps module does't seem to be part of the standard installation of python 2.7 coming with QGIS 2.14.1 installed via OSGeo4W installer (allthough i read somewhere that gps module ist part of the standard Python installation).

Platform: Windows10

>>> import gps
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named gps

However, trying to install some related modules (gps, gps3, gpsd, GPSReader) via OSGeo4W shell gives me errors like

C:\Users\Jochen\Downloads>pip install gps3
Collecting gps3

But

gps3 (0.1a)  - Python2.7- Python3.4 gpsd interface

lists the gps3 module for example.

I simply need lat/lon from gps, which modules to install and how? Or any other hints of how to achieve this?

Some things I found in this context:

https://trac.osgeo.org/osgeo4w/wiki/ExternalPythonPackages

How to install 3rd party python libraries for QGIS on Windows?

A little more research (google for 'qgis python access gps') brougth the solution, once more as simple as obvious, and with no additional python modules to be installed.

I found this:

http://imasdemase.com/programacion-2/get-gps-info-qgis-python-console/

My spanish is not the best (if any), but i understand the code mentioned which works fine:

connectionRegistry = QgsGPSConnectionRegistry().instance()
connectionList = connectionRegistry.connectionList()
GPSInfo = connectionList[0].currentGPSInformation()
lon = GPSInfo.longitude
lat = GPSInfo.latitude

that's all.
