auth
is a tuple with
(sec, key)
. Security can be
None
, WLAN.WEP, WLAN.WPA,
WLAN.WPA2 or WLAN.WPA2_ENT. The key is a string with the network password. If
sec
is WLAN.WEP the key must be a string representing hexadecimal values (e.g.
ABC1DE45BF
). If
sec
is WLAN.WPA2_ENT then the
auth
tuple can have either 3
elements:
(sec, username, password)
, or just 1:
(sec,)
. When passing the 3 element
tuple, the
keyfile
and
certifle
arguments must not be given.
bssid
is the MAC address of the AP to connect to. Useful when there are several APs
with the same SSID.
timeout
is the maximum time in milliseconds to wait for the connection to succeed.
ca_certs
is the path to the CA certificate. This argument is not mandatory.
keyfile
is
the path to the client key. Only used if
username
and
password
are not part of the
auth
tuple.
certfile
is the path to the client certificate. Only used if
username
and
password
are
not part of the
auth
tuple.
identity
is only used in case of WLAN.WPA2_ENT security.
wlan.scan()
Performs a network scan and returns a list of named tuples with
(ssid, bssid, sec,
channel, rssi)
. Note that channel is always
None
since this info is not provided by the
WiPy.
wlan.disconnect()
Disconnect from the WiFi access point.
wlan.isconnected()
In case of STA mode, returns
True
if connected to a WiFi access point and has a valid IP
address. In AP mode returns
True
when a station is connected,
False
otherwise.
wlan.ifconfig(id=0, config=['dhcp' or configtuple])
When
id
is 0, the configuration will be get/set on the Station interface. When
id
is 1 the
configuration will be done for the AP interface.
With no parameters given returns a 4-tuple of
(ip, subnet_mask, gateway, DNS_server)
.
If
dhcp
is passed as a parameter then the DHCP client is enabled and the IP params are
negotiated with the AP.
If the 4-tuple config is given then a static IP is configured. For instance:
wlan.ifconfig(config=( '192.168.0.4' , '255.255.255.0' , '192.168.0.1' , '8.8.8.8' ))
