OK, so this is definitely a problem with Wireless AA and/or Android. I had indeed set it up correctly I.e. I had not explicitly set up a WiFi connection to the wireless AA dongle, I just paired to its Bluetooth as required. What Wireless AA does is that it will create its own WiFi connection between the phone and the dongle. It does this without showing the WiFi icon on the phone. But you can see the WiFi connection made when you go into the WiFi settings. So it appears like WiFi is not used but it is.

Now if I force select the car's WiFi hotspot, the phone will briefly make a connection to it, but that stops AA. However worse still then AA will grab the WiFi connection again and kick you off the WiFi access point you selected.
This behaviour is irrespective if you are in the AA MMI menu or not. Because for the car, and the phone, the fact the Wireless AA dongle is plugged in that means that I want to use AA and I have to forgo my ability to use the car's data connection. Man this sucks.

I use an iOS device along with a wireless dongle, which works fine for connecting to the car's hotspot while using CarPlay. It sucks that AA forces you to use your phone's data rather than the in -car hotspot.

A quick search of Reddit posts showed that this behavior is not car brand, phone model or head unit specific, as VW and BMW owners with different Android phone models are all reporting the same thing. Sorry...

Yes this really sucks big time. My only option now is to move the unlimited data SIM into the second SIM slot on the phone. Which is a poor solution but atleast it won't make the main phone's data run out due to AA. It will also mean that all the others in the car won't enjoy the car's WiFi network.
And ofcourse Samsung in their wisdom makes you choose between an SD card and a second physical SIM!

In that setup, can your passengers connect to your phone's hotspot -since that SIM has unlimited data- for internet access, while your phone is connected to the car via AA? I hope AA connection doesn't disable your ability to generate a hotspot and/or allow others to join.

I will need to check that. But even if it works, its a horrible option. It means that the phone with the hotspot has to be in the car to provide the connection. At the moment, the car is the gateway and this way my Audi Connect traffic also goes through my car's own SIM. That will stop too!!

There's a similar issue with that. The phone can't be a hotspot while using Wi-Fi for AA. As far as I know this doesn't work with iOS, either. Can't use the Wi-Fi for anything else if the hotspot is active.

This I know is possible on Android atleast and we use this all the time when at hotels and airports. Sometimes hotels/airports will give you only 1 wifi login, so one of us logs in and then creates a hotspot for the rest of us. That works fine.

Good to know. I know this works with Windows, too. Maybe it works in the latest iOS as well now, I've never tried, but Apple made changes to the hotspot a while back. It's always on now, whereas previously you had to turn it on first, and then it dropped the existing Wi-Fi connection to free it for the hotspot connections from what I remember.

I don't think you can do wireless AA just over BT, you need the WiFi bandwidth.
