I have been trying to get this to work for over a week now, with two GPS modules and two different GrovePi boards, just in case the RPiser connection is faulty.
This is the latest Raspbian Stretch, and a fresh install of grovepi libraries using curl.
When I ran the various GPS test programs for python, I have modified them with brackets to allow for the changes in python3. I am usually using thonnyIDE. I have not touched UART in the config file, even though some articles discussing the GPS have indicated that is a solution (but I see no information on Seeed or Dexterind about this).
I ‘do’ know that accessing the GPS will disable a Bluetooth mouse if one is connected, and that is an indication of AMA0 conflicts (?!?)
I am getting nothing from these GPS modules, absolutely nothing. How can I make these devices work the way they are intended to?
