I would like to run the Raspberry Pi Wi-Fi hotspot independently of Hudiy so the hotspot remains available if Hudiy is stopped, restarted, updated, or crashes.

I tested this by cloning Hudiy's NetworkManager connection:

```bash
sudo nmcli connection clone "Hudiy AccessPoint" "Truck Hotspot"
sudo nmcli connection modify "Truck Hotspot" connection.autoconnect yes
```

The cloned AP uses the same basic configuration as the Hudiy-created AP:

```text
802-11-wireless.mode: ap
802-11-wireless.band: a
ipv4.method: shared
ipv4.addresses: 192.168.12.1/24
```

With Hudiy's hotspot option disabled, `Truck Hotspot` starts automatically at boot and works correctly. DHCP, NAT and Internet sharing all work. A laptop connected to it has Internet access through the Pi's cellular modem (`usb0`).

Hudiy itself also starts and runs normally.

However, **wireless Android Auto will not connect while Hudiy's hotspot option is disabled**, even though the external hotspot is already running and working.

I confirmed this several times. A packet capture on `wlan0` showed that the Android Auto connection was not being initiated at all.

The interesting part:

**If I enable the Hotspot option inside Hudiy, Android Auto immediately connects.**

This suggests the Hudiy Hotspot setting is doing more than creating/managing the NetworkManager AP. It appears that the setting also enables or initializes some part of the wireless Android Auto connection.

Would it be possible to separate these two functions?

Ideally I would like to configure Hudiy to:

1. Not create, stop, or delete the Wi-Fi hotspot.
2. Use an already-active hotspot on `wlan0`.
3. Still initialize wireless Android Auto exactly as it does when Hudiy's Hotspot option is enabled.

The intended setup would be:

```text
Raspberry Pi boots
|
+-- NetworkManager starts permanent hotspot
| |
| +-- Internet shared from cellular modem
|
+-- Hudiy starts
|
+-- Wireless Android Auto uses existing hotspot
```

This would make the vehicle Wi-Fi network independent of the Hudiy application.

For reference, I'm running Hudiy on a Raspberry Pi 5 under Raspberry Pi OS/Debian Trixie.

If there are additional logs or configuration files that would help diagnose this, I'm happy to provide them.

To use an external wireless network (not created by Hudiy), you must disable the hotspot and then set the SSID, passphrase, and hardware address of your network. You also need to set the appropriate IP address at which your Raspberry Pi is accessible on that network.
