How to make seamless wireless connection?

[Karabacak021]

Hey! Thank you very much for the work, the app is really good :)
I would like to ask for a little support to make it work better.
My plan:

1. When I turn on the ignition of the car, it should start HURevived on startup. (done)
2. When I place the phone on the wireless charger, it should turn on the hotspot. (done)
3. The head unit should automatically connect to Wi-Fi. (done)
4. As soon as it connects to Wi-Fi, the Android Auto session should start. (this is where I’m stuck)

What I absolutely do not want is to involve Bluetooth in the process, because it causes conflicts between the car’s Bluetooth hands-free system, Android Auto hands-free, and my smartwatch when they are all active at the same time.

Either I start the server in the Android Auto settings and then tap Wi-Fi in the Revive app,
or I press Start in the Wireless Helper app and then tap Wi-Fi in the Revive app

This way it’s really not seamless at all.
I’ve managed to get to the point where the phone turns on the Wi-Fi hotspot and the head unit connects to it — but what next?

Thank you in advance for your supportive help :)
Phone: Xiaomi 12, HyperOS 2.0.208.0, Android 15
Headunit: Chinese Android 10(fake, around 8.1) 1024x600 10", Allwinner quadcore T3 P1, 2G RAM, 32GB ROM

P.S.: I found a small bug. If I keep changing the resolution and DPI, then connect, disconnect, change the resolution and DPI again, and repeat this several times, eventually the resolution gets stuck. The image on the head unit’s display then becomes either smaller or larger than the screen — meaning it either overflows beyond the edges or is centered with black borders around it.

Hi, thanks for your detailed info! If you get to autostart wireless helper as well, as starting the hotspot, it should work out of the box. If using Wireless Helper Mode in the settings of HURev, the App will scan and search for wireless helper app and the wireless helper app does the same if you have set the setting to Phone Hotspot Mode. May take up to 5 seconds, if they missed the first time period, but they should find each other in the second search. Did you try that too?

Ah I got it work partially. Now only I need to press the button in the Wireless Helper app.
The Auto Start Service functions does not help, because "On Bluetooth Connection" is not ideal for me and "On Specific Wi-Fi Connection" is not activate with hotspot. Maybe if you will have time in the future, can you add "On Hotspot Connection" or On Wireless Charging"? Or if not possible, is there any android intent command which can turn it on? Then I can add turn on command to Tasker.

The new version of wireless helper now have 2 intents:

Please try them :)

I tested both, and the start function works like a charm :) Thank you very much!!
I will not really use the stop function, but I tested it and it have a little issue on the Revived side.
If I send the stop command it stops, thats okay.
However, when I send the start command again, the Helper starts searching, but the Revived app doesn’t respond.
Pressing the WiFi button connects instantly.
Closing and reopening the Revived app also connects instantly.
In the Revived settings the wireless connection mode stays on Wireless Helper(waiting for phone)

Yeah thats a wanted feature of HUREV. If you stop the connection by yourself, I send a flag to know that it was wanted and not due a connection issue. And if so, the auto search is disabled as long if as you are not clicking the wifi again. If not, it would bring you instantly back to Android Auto. That is not what you want if you close the connection. You will get to loop where you are not able to close it.

I understand, then it works well too!
