I'm struggling to get iOptron driver to recognize GPS source attached to my mount.
I've attached screen shots of Options and Mount Info panes of the INDI control panel for the (connected) mount. The GPS dongle had signal and the driver seems to recognize this "Data OK," but it still wouldn't correctly set either the location or the time. I was able to do it manually, but this is frustrating.
Perhaps I'm supposed to enter something clever in the "GPS" box on the "Options" tab, but I don't know what that is! I've tried typing Mount, and GPS, and Dongle but I don't know what INDI wants in there.
In summer I image at a remote mountain sites without main power or any kind of internet, so when I have trouble it's hard to research why!
IIRC, you need to set in your handset that the GPS is the Time Source and it would be reflected in the driver. So Ekos does not see GPS separately, but the time/location coming from the mount as GPS ones. Select "Mount update KStars" and you should be good.
I don 't know about the CEM40 but the GEM45 can be connected to a computer with a USB cable without the need to connect the hand controller. For the latest KStars/Ekos/INDI we needed to update the firmware of the mount and while we were at that, we also updated the firmware of the hand controller. Once that is done, the GPS module is NOT visible to Ekos. But, as Jasem already explained, by simply selecting Mount Updates KStars swith both Time and Location selected we see that KStars uses the GPS location and time. The system time does not get updated though.
