This weekend I got to a dark sight with clear skies, mobile power and no internet or Skysync GPS. This is all using the RPI3 as a wifi AP, and controlling the EKos imaging sessions and scheduler with an iPAD using VNC. Yes, it is worked well in the end, very easy and portable.
Problem: The Mount does not seem to be able to update the RPI3, or KStars for date time and location.
Desire workflow: Execute Celestron's Two Star Alignment on a CGEM, and also on a 6SE. Put in the custom site long. lat., date, and time. Align the mount and all works really well. Connect/Power-up RPI3, start Kstars and Ekos/INDI matches the time and date, and location set on the mount. Whether connecting to INDI on the RPI3 via VNC on RPI3, or Mac using Kstars, or slewing via SkiSafari, all do not change the time/location settings on the CGEM, and in the case of the RPI3 KStars or Mac Kstars, Kstars matches the time and location of the mount. In the case of SkySafari, it any time/location is turned off.
Problem: CGEM Mount does not seem to update KStars/INDI on the RPI3 (did not get to test Mac)
Attempted solution: INDI Settings -> Device updates, Select Device and check off Time and Geographic location. This setting was done before starting INDI.
Symptoms:
1. Kstars remains at Feb 2, 2016
2. RPI3 itself remains at Feb 2, 2016, ie. rpi3: ~$ date
3. RPI3 image files are saved with Feb 2, 2016
When I am home this is not an issue as the RPI3 would update Date/Time on boot via NTP.
I learned to enter the Long/Lat in the INDI driver for the mount on site location tab, and can almost do same for the Time date via converting to UTC.
If there is a log to send along let me know, and I will try to provide it via specific test. There did not seem to be anything of note though.
Please let me know if you have any ideas.
