This example prints the WiFi 101 shield or MKR1000 MAC address, and
|
||
|
|
scans for available WiFi networks using the WiFi 101 shield or MKR1000 board.
|
||
|
|
Every ten seconds, it scans again. It doesn't actually
|
||
|
|
connect to any network, so no encryption scheme is specified.
|
||
|
|
BSSID and WiFi channel are printed
|

Circuit:
|

|

WiFi 101 shield attached or MKR1000 board
|
||
|
|
