Has the fix been pushed to other environments as well? I'm seeing this issue for a fresh build of RPi2 running Ubuntu Mate 15.10.1 (more details below)
Thanks, David

FYI...I opened #PKB-613-80090 with Celestron on Apr 19 about the 'h' command not working. No feedback yet.

I applied the latest updates from PPA and my mount is responding so looks good.

I decided to download the INDI code in an attempt to debug what the underlying issue might be. celestrondriver.cpp appeared to be the code for gathering the mount info and, with the help from a NexStar Communication Protocol doc, I identified the driver commands.

For the first message:

DEBUG	91.342043 sec	: CMD (m)
DEBUG	91.364547 sec	: RES (14 23)
WARNING	91.364775 sec	: Unrecognized model (20).
I added a couple of lines so that my AVX mount (i.e. model 20) would be identified.

For the 2nd message:
DEBUG	91.474998 sec	: CMD (h)
ERROR	96.477992 sec	: Timeout error
the command "h" is to read the time/date from the mount. There didn't appear to be any issues with the code, so I used the UNIX "cu" command to connect to the hand controller's serial port and manually send the command and view the output. However, no matter what I did, the "h" command always timed out and left the hand controller unresponsive. My guess is "h" is no longer a valid command, at least with the version I have (5.28).

The only alternative I could think of was to remove the "h" command call from the code, and use the hard coded simulation values as the returned time/date. Doing this allowed the mount to be controlled, I was able to use the slew buttons to engage the mount motors, as well as choose objects in KStars and have the mount motors engaged to move to them. RA/Dec values were returned, though keep in mind this was only a test in my basement. I'm not sure what effect changing the code this way will have as far as the overall INDI code goes.

I have VNC already running which I can set up to pass through my FW, is that good enough?

Hummm, I have not used TeamViewer before. Let me check it out and see if I can get it working on the RPi.

Hi, yes I see the same error each time I connect. Do the errors refer to date/time, or RA/DEC? And once I get these errors, the mount hand control freezes and I have to power cycle the mount to connect again. I do set the date/time in the initialization process when the mount is powered on, then start the connection with KStars.

I get this "Failed to read RA/DEC values" error when connecting using KStars to my Celestron AVX mount. I'm running Ubuntu (wily) on a RPi2. Has anyone else experienced this, and/or is this a know issue? Below is the debug log from the session, and software versions are at the end. Any help would be appreciated.
