Using and programming a NEO-6 GPS receiver module
If you for some reason don’t know the baudrate you can either try different settings in the uCenter and see at which setting the displays come to life or you can use terminal emulation software like RealTerm to find the correct baudrate. At the right baudrate the GPS should be giving out “human readable” NMEA sentences like these. If you just get garbled characters the baudrate setting probably is not right.
Alternatively you could use the Text Console which is a part of uCenter software itself (View->Text Console or F8 button), but this one will only show text data when the setting is right, so you can’t really check if you are actually receiving data, but at wrong setting.
After you successfully connect to your GPS the displays will start showing some data. If you don’t have GPS fix the data will be somehow limited, but when the GPS gets valid fix, all of the displays will work. You can also experiment with the additional displays available via the top bar buttons. Here I have opened Sky View and Deviation Map. The latter is really useful for determination of accuracy and time stability of position information.
Configuration for the module can be accessed under View->Configuration View
Here you can find multiple settings, and there are a few that should probably not be touched, such as antenna and oscillator settings. Note that you may brick the module if you set wrong parameters (most programming errors can be recovered, but soldering may be needed).
The settings of most interest are the MSG settings, where you can set which messages are being output and to which devices and PRT – port settings.
