Android Auto and how it would handle 2 WiFi connections

[emeeder]

I need to always have access to a "free" WiFi connection for a separate python project.

Will the HUDiy/AA system always only use wifi-0 to grab the pipeline to to my phone, or will it sometimes grab wifi-1 if it's free?

By default, Hudiy uses the first available Wi-Fi adapter to create a hotspot. The order of the adapter is controlled by NetworkManager from Raspberry Pi OS.

You can also specify the hardware address of the Wi-Fi adapter to be used for creating the hotspot in main_configuration.json:

Perfect... thank you!

Okay... I've got the Raspberry Pi 5 running with the two WiFi cards (wlan0 and wlan1), and I tried to put the MAC address of wlan1 into the "hardwareAddress" field of the main_configuration.json file under hotspot but for some reason it just didn't work.

(Now at least it didn't blow up the Pi's SSH/RDP/sFTP pipes, but HUDiy just sat there and AA wouldn't start.)

Is there something else from the default settings that I need to tweak in order for the HUDiy/AA stuff to launch using the wlan1 instead, or am I just having terrible luck?

Is the hotspot icon visible in the status area next to the clock? Are you able to connect to the hotspot from other devices?

USB Wi-Fi adapters may have limitations when creating 5GHz hotspots because the 5GHz band is strictly regulated by local laws in most countries. You can check this thread:

Everything is working GREAT!

Dual WiFi connections, 24/7 (basically) access to Gemini 3.1 model for A.I. interactions, smart home access, Google calendar, tasks, shopping list, and alarms

Mute AA music with wake-word... very clean.

HUDiy is controlled by the Python script with touchscreen power on/off.
