I've used Phidgets for years with zero issues until today.
I have a phidgetGPS connected to a Rasperry Pi.
the VB NET example code runs fine on my Windows PC, as does the Python code on the Raspberry Pi
However, with the VB net code on the Raspberry Pi, the GPS numbers dont seem to update very often (like once every 5 minutes) and also, the numbers are off by about a kilometer. The event seems to be firing ok, just the numbers are not changing (Latitude, Longitude etc)
I've tried The Phidgets 21 library and the 22 library. I've also eliminated hardware and my code as issues by going back to basics with the sample code. My Raspberian is up to date as is Mono and the Phidgets Library.
I hope someone smarter than me can give some advice on what to do.
The .NET library is available for .NET Core. We do have documentation for Mono on Linux, but you should be able to also use .NET Core on Linux - are you having any specific problems?
