#How to scan for wifi networks when already connected to wifi?

Hi, it's probably easy but I can't seem to find out how I can scan for wifi networks. I always get the error "wifi already connected or established". I read some posts by @bmentink and I tried
but the result is the same.
Can I use an active wifi connection to scan for networks? Or is it physically impossible to scan for networks when a wifi connection has already been established? (I didn't think so, but I might be wrong, - it happens.)
jag run -D jag.disabled -D jag.timeout=20000s webserver.toit --assets webserver.assetsbut the result is the same.

(I just checked with my old Arduino software and it can scan for networks while having an established wifi connection.)

I think Toit doesn't support scanning while being connected (yet).

OK, thanks Florian, no worries, I'll put that one aside then for now. Should I make an issue/request for it somewhere?(edited)

I just looked at the code.

It seems like we just abort the scan if we are already connected.

I removed that check, and things just seem to work.

Will write a PR, and it will likely be in the next SDK release.
