Well the chip needs to know to which "interface" to attach the server. So most likely it is configured to attach it to the AP side if available. You'd need to modify the firmware to start it on the STA side if available. Or start one on each if you want.

Maybe a bit off-topic, but why wouldn't it just listen on 0.0.0.0?

I was thinking that there was just a translation of terms issue.

I've been working on the idea that STAtion (client (0)) means client. AP (1) meant server.
So if you want client and server capability then (3).

Don't know why to use the term AP as in Access Point. A Access Point does
more than what it appears this firmware can do so far. Perhaps when the firmware
stabilizes and the documentation gets caught up we will know more.

STA and AP are the WiFi dedicated terms for these functions, and you can be on or the other, but not both. Mode (3) is actually STA (client) + SoftAP (software AP or server), where while you are connected to an AP as a station, you provide an "software" AP at the same time.
