About SSID list acquisition

[AkKo_4458241]

Hello.

I want to get the SSID list in order of signal strength by referring to the file(ThreadX_NetX_Duo_Scan.c).

(1) How long does it take to get one list? (time per outer while)
     When I tried, it was around 1.0 second.
(2) If there are many access points around, does this time increase?
(3)Will access points with strong signal strength be added to the list preferentially?

Thank you.
