Bedankt, Hans

Looking at the log it looks more or less ok. wpa_supplicant (assume you
use that) first does three regular scans which end with no APs found.
Not sure why that happens unless you are in a shielded room :-) After
those scans wpa_supplicant tries to tell the device to do a so-called
scheduled scan. Basically, it is a scan offload. However, the driver
still thinks there is a regular scan ongoing. This needs to be
investigated more. I tried to get your repo from github, but got:

error: The requested URL returned error: 403 Forbidden while accessing
