Thx.
Yes used and it works!
I would like to know also the related WiFI channel (1 to 13 in 2.4 GHz) of any detected SSID.
It seems that the ATSAMW25 has this info but it's not developed in the WiFi101 library.
I'm not so expert to modify the existing library so the question and the possible help.
Thx for any help
