[Bug] Q6 HE connectivity switch incorrect

[svdgriendt]

Describe the Bug

When using the 2025q3 branch (as per recommendation) and running qmk compile -kb keychron/q6_he/ansi_encoder -km keychron it does produce a file that works. However, I have to switch the toggle from USB (which I want to keep using) to Wi-Fi/2.4gHz in order to use the keyboard in USB mode.

I've checked and part of the reason seems to be this specific line.
https://github.com/Keychron/qmk_firmware/blob/2025q3/keyboards/keychron/common/wireless/keychron_wireless_common.c#L299

There's a match on 0x02 and if I change that to 0x00 then the keyboard works with the connectivity switch on USB (that's the middle) while connected via USB only. Otherwise, the effect is that it seems the keyboard is in either Bluetooth or Wi-Fi/2.4gHz mode, as any key pressed will flash the 1 key.

Now I may have been decoyed into something, but this does seem to work for my case. I'm not sure if this would break Bluetooth or Wi-Fi/2.4gHz though, as I don't use those, so please be extra careful there.

‼️ Important note: the change mentioned by qmk doctor are two things

• I copied the q6_he directory just to have an easy comparison as I didn't set up a fork
• I changed the line mentioned from 0x01 to 0x00
• But note that even before I went into making these changes, I noticed this behavior and that caused me to investigate
