I have done it before.

Although it's pretty much the same as what you have there.

Subject: [Qgis-developer] Connect to GPS device<br>
<br>
<br>
<br>
Hello<br>
<br>
I am working on a Python plugin for QGIS 1.8. My goal is to automatically connect to \
a gps device at<br> a COM port. I tried to clone some code of \
qgsgpsinformationwidget.cpp and looks like this:<br> <br>
---------------------------------------<br>
from qgis.core import *<br>
from qgis.utils import *<br>
from PyQt4.QtCore import *<br>
from PyQt4.QtGui import *<br>
<br>
devices_combo_box = qgis.utils.iface.mainWindow().findChild(QComboBox, \
'mCboDevices')<br> com_port = \
devices_combo_box.itemData(devices_combo_box.currentIndex()).toString()<br> detector \
= QgsGPSDetector(com_port)<br> QObject.connect(detector, SIGNAL("detected( \
QgsGPSConnection )"), self.connection_detected)<br> QObject.connect(detector, \
SIGNAL("detectionFailed()"), self.connection_detection_failed)<br> \
detector.advance()<br> <br>
def connection_detected(self, gps_connection):<br>
QMessageBox.information(None, "Information", "Connection \
detected", QMessageBox.Ok)<br> <br>
def connection_detection_failed(self):<br>
QMessageBox.information(None, "Information", "Connection detection \
failed", QMessageBox.Ok)<br>
---------------------------------------<br>
<br>
So I first choose the correct port in the QGIS GPS Information Widget (mCboDevices) \
and then run this<br> code but nothing happens.<br>
<br>
If I initialize detector with something like QgsGPSDetector('test') than \
connection_detection_failed is<br> called (as expected). With \
QgsGPSDetector('COM5') or QgsGPSDetector('\\\\.\\COM5')<br> \
connection_detection_failed is not called but connection_detected either. Do you have \
any idea what<br> I am doing wrong? Thank you very much.<br>
<br>
Regards, Josua<br>
