Sorry for the time lapse silence. I have been testing and wanted to give you a final solid update.
I cycled my problem Berry unit through 3 RPi 3 boards with no success. I have tested with clear view to sky. I placed the unit back atop my second Pi Zero W and it works. Granted it does not fix as easily as the original Berry atop another Pi Zero W but it works and works pretty well. Both units maintained 3D fix consistently on a road trip around town and through a wooded area (Park like).
So I took the original Berry off the Pi Zero and put it on the RPi3 and sure enough it linked up pretty well getting to a 3D fix in a minute or less. Outside with clear view of course. So it is definitely an issue with the combo of the second Berry Unit and the RPi3 units.
The only thing I did with the Berry was to solder the pin socket on as required. I am not a novice at soldering but I also do not have high end (temp reg) equipment. I use a standard Weller Soldering Iron for my work. I don’t remember if it is 25 or 30 Watt. Given that I tested all RPi3 with USB only I would question if a soldering issue could be in play? Should I re-solder the joints? Could I have slightly damaged it in the soldering? I tend to leave cold joints as opposed to over heating but anything is possible.
A final update with you thoughts on this issue would be appreciated.
PS> LTE in the future? Why is the GPS-GSM no longer on Amazon? Why was it cheaper on Amazon?
