Accessing ZiGate via the USB port of the Wifi module?

[pdecat]

As wireless connection to the ZiGate is currently unstable (cf. #3), is there any mean to access it via USB using its USB-Wifi module?
Or can that only be done using the USB-TTL module?
I ask because I'd rather avoid having to swap modules between experiments.

When plugged, that USB-Wifi module is seen as:

# dmesg | tail -6

Bus 003 Device 039: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter

I've tried to naively put that ID in the discovery code:

git diff

With the current wifi module firmware it's not possible but it could be a good thing and it's possible

I close this issue since this is not related to the library.
Please ask the vendor to add such feature in a next firmware release.
