Moitessier HAT firmware update failed after update to OpenPlotter 1.2

gpsd is a daemon that receives data from a GPS receiver, and provides the data back to multiple applications such as Kismet or GPS navigation software. It thus provides a unified interface to receivers of different types, and allows concurrent access by multiple applications.


GNSS
 
GNSS stands for Global Navigation Satellite System, and is the standard generic term for satellite navigation systems that provide autonomous geo-spatial positioning with global coverage. This term includes e.g. the GPS, GLONASS, Galileo, Beidou and other regional systems. GNSS is a term used worldwide The advantage to having access to multiple satellites is accuracy, redundancy and availability at all times.  Though satellite systems don't often fail, if one fails GNSS receivers can pick up signals from other systems.  Also if line of sight is obstructed, having access to multiple satellites is also a benefit.  Common GNSS Systems are GPS, GLONASS, Galileo, Beidou and other regional systems.
 
GPS
 
The United States' Global Positioning System (GPS) consists of up to 32 medium Earth orbit satellites in six different orbital planes, with the exact number of satellites varying as older satellites are retired and replaced. Operational since 1978 and globally available since 1994, GPS is currently the world's most utilized satellite navigation system.

Hi Jim, did I thank you for your help lately? And for your patience? Much appreciated.

I'm not sure where you mean the setup needs to happen - "gpsd or gps"? Do you mean in Raspbian or in OP on the Serial tab? 
  • I first did a clean install of OP and Moitessier by following the instructions in the manual. 
  • I then did the update to OP 1.2 and the appropriate sw for the Moitessier. 
  • I checked the boot log and there were no errors 
  • I went through the manual again checking the settings in both OP and Moitessier
  • On the Serial tab in OP only the Moitessier was visible, and I used the "auto" button the set the variables as instructed. This assigned GPSD to the Moitessier HAT. There is no "GPS" option.
  • If I then run the Diagnostic on the kplex tab I get the results I reported earlier with no lat/lon info
  • To be honest I was not clicking on the "start" button for the Moitessier. I am still not certain if I have to do this every time I power on the RPi. I most certainly hope not, but the documentation is unclear to me.
  • I also realized, too late, that there is a GNSS Enable button on the Moitessier HAT. What is disconcerting is that when I click on the Settings tab in the Moitessier HAT app I get a message that "All changes will be temporal. Default settings will be loaded after rebooting."
  • I don't see a way in which I can save the current settings as the defaults. So does this mean that I need to enable GNSS every time I boot the RPi? That would be nuts, but I don't see any other way, assumign I am reading the message corectly.
It was out of frustration that I connected a GPS USB puck. I now have the Moitessier HAT assigned to Kplex on the OP Serial tab, and the GPS USB puck assigned to GPSD. I boot the RPi and I get lat/lon info without having to activate any other settings. But this is not my preferred config, I'd really prefer to just the Moitessier HAT.

As a side note the USB GPS puck and the Moitessier HAT puck are sitting side-by-side on my window shelf, so they are getting the identical signal.
