Information Required: Celestron GEM mount Auxiliary driver

Information Required: Celestron GEM mount Auxiliary driver was created by Jasem Mutlaq

I'd like to see if some users can test their Celestron GEM mount (CGX / CGEM / VX) with the INDI Celestron AUX driver and post the driver logs here. Here are the instructions:

1. Put the mount in the home position: Counter-weights down and looking at the celestial pole.
2. Cycle power to the mount.
3. Enable mount logging in INDI/Ekos (check signature)
4. Create a profile with Celestron driver (only VX or CGEM or CGX).
5. Start profile.
6. Share logs

This is mostly to know the mount initial encoder position on startup. IIRC, some mounts were reporting 0 encoder values on startup, while other were reporting 90 degrees on startup.

Trying to do this, but get this error:

2023-01-28T23:49:51: [ERROR] Cannot continue without connection to motor controllers.
2023-01-28T23:49:51: [ERROR] Got no response from target ALT or AZM.

This is the first time I've tried to connect my CGX using the AUX driver and connecting it directly to the mount. I've followed the AUX driver directions from the webpage.

Connecting directly using which cable and which port?

USB from StellarMate to USB port on top of the mount.

Can you double-check your serial settings? My AVX is connected like this:

Port: ttyUSB0
Baud: 9600
Type: USB/HC

I did set "last alignment" on the HC before starting Ekos and had some difficulty getting the driver selected properly, but the "CGX Wired" driver option make it much easier than previous attempts.
The driver seems to be working (in daylight), so if there are outstanding issues, I haven't yet encountered them

Hopefully, my log is attached. (I did slew around a bit after connecting).

So after a number of days of attempting to use the Celestron AUX driver, it's not working for my CGX mount connected via the PC port. I've tried it with/without the handset connected.

The 1st issue is that the driver assumes that the mount is in the index position when starting. This requires I align / polar align the mount (via the hand set) and then power the mount off / on and choose last alignment, to be able to get to the index position. I don't see a more reliable way of doing this. It would be better (for me) if it interrogated the mount where it was pointing (as it's likely still pointing at my polar alignment star).

The 2nd issue is that regardless of where I slew the mount, the Mount tab always reports East (pointing West), even after the mount has obviously just done a meridian flip in reaching the target. If I turn on the "Flip if HA > x" checkbox, then it repeatedly tries to do a meridian flip (while not actually doing anything at the mount).

These may easily be setup/configuration errors on my part, but that is not obvious. If I switch back to using the HC usb interface with the Celestron CGX driver then neither of these issues exist.

Sorry to post this right after a stable release, but it's not critical as there is a working alternative.
Cheers

send the log.

●Environment
Mount: AVX
AUX connection: Self-made USB serial, self-made WIFI connection (both connected to HC terminal)
Hand controller: Not connected.

As I reported before, I think that the reference point of the home position differs by 90 degrees between the fork equatorial mount and the German equatorial mount.
I think that it is highly likely that you will get different results if you connect directly to the hand controller. (because the hand controller has alignment information)

Result of connecting
・Self-made USB serial → connection not possible
・Homemade WIFI connection → connection

Homebrew USB serial can be used in Windows, but INDI does not recognize it. (also same as before)

RPI4 (32-bit OS), so it may not be the latest update.
