You are right. The AUX port needs level converter and just *looks* like serial port (and communication is over standard serial protocol). If you connect it with serial port you are indeed likely to fry at least one and possibly both ends of the connection. The HC serial socket is much better but it is not clean passthrough - you send commands with a prefix and you only get responses - so you cannot listen for broadcasts on the AUX bus - that limits possible functions a bit.
I have no AUX adaptor thus the HC variant will be implemented first, but the difference is essentially the prefix, so it will be simple switch.
I've also seen a nice hack with RPi0w mounted *inside* the HC providing the INDI interface to the HC.

Nexbridge is, as I understand, just a specialized bridge tcp<->serial and does not interpret the communications.
The nexstarevo is an indi driver for celestron wifi telescopes using celestron AUX protocol. Currently it should work with NexStar Evolution and other nexstar telescopes with skyfi adaptor. In the future I plan to implement also wired connection to any Celestron with AUX port (most of them).
It is similar in idea to EqMod driver for skywatcher mounts. Both talk directly to the motor controllers and play the role of hand controller.

This is a different protocol. This library uses high-level celestron/skywatcher protocol implemented by the hand-controller. The NexStarEvo driver in indi uses low-level AUX protocol to control the motor controllers. This is the only protocol available over WiFi in this scope.
OTOH the high-level protocol is already implemented by the celestron driver so there is no point in duplicating it. I think you can implement this "nudging" idea by simply scripting the INDI celestron/camera driver + astrometry in python and if it proves effective I am sure Jasem (or you yourself) will add it to the slewing logic as an option in Ekos.

The NexstarEvo driver is almost what you need - unfortunately it needs wifi connection to the telescope. I intend to implement wired link support in the future but have no hardware to test it on. It was never tested on the german mount as well.
But you should be able to use timed movement commands of the celestron driver to nudge the mount to the correct place.

Can I have a look at your code please? I have implemented the whole AUX driver for indi: nexstarevo driver. The missing piece is the wired interface - right now it only works over wifi, and testing with german mount. So far I have tested it only on fork AltAz mounts but in principle it should work for equatorial orientation. Maybe We can use some of your code to improve the indi driver?
And you are right - standard celestron driver is a totally different beast.

Even more helpful may be the python library I have written for the satellite tracker. You can lift the interfacing code right out of it.

I missed your post about the goal. If your goal is to write a direct AUX client without astronomy context indi is not a right route IMHO. You can write much simpler interface code in python3.5+ using async/await. See the simulator code in the indi driver - it is almost complete mount simulator written in python in few hours. There is also some skeletal code in the mentioned github repo which you can use as a starting point. I am writing an independent satellite tracker for the mount so I would appreciate if you tell us how is it going with your project (github repo?) - maybe I can also reuse some of your code.

Addendum: some changes in libindi must have disagree with my driver and recent build stopped working - I recommend the last released version. I'll fix it soon but not today sadly.

Celestron driver is not going to work in wifi mode. The Nexstar Evolution is using AUX protocol over Wi-Fi. You need to use nexstarevo driver or celestron driver over serial connection to hand controller. The NS-evo driver is beta-quality but should work and I, as a primary author, will be happy to help you make it work. I would really appreciate any feedback concerning this driver.

The issue is probably fixed by PR: github.com/indilib/indi/pull/229
Can you test if we can close the issue?

Yeah, I've found it as well. Nice catch and brillant idea - and so simple to build.
