I am with NON OS SDK 2.0.0.
Commands seems to work well, but at the end of my scan after a positive match with a specified AP i noticed that wifi_station_connect() performs a new scan before the module gets connected.
Now, my mandatory goal is to reduce current consumption at startup end therefore to speed up the connection sequence.

I wonder :
- Is it normal that wifi_station_connect() does its personal scan even if mine was successful ?
- Is it possible to avoid this extra scan and pass scan result as connection target ?

Thanks in advance.
