==============================
Configuring a Wireless Network
==============================
``wapi`` is used to connect to an Access Point by setting its parameters.
.. note:: Usually, one single wireless interface refers to an operational
mode: Station Mode (STA) or SoftAP. For instance, ``wlan0`` may refer to
the STA mode and ``wlan1``. Setting the passphrase and the ESSID of a
STA-enabled interface would make it connect to a wireless network while
setting the same parameters for a SoftAP-enabled interface would provide
a network wireless with these connection parameters. Please check
:ref:`ESP32 Wi-Fi Station Mode (wlan0) <esp32_wi-fi_sta>` and
:ref:`ESP32 Wi-Fi SoftAP Mode (wlan1) <esp32_wi-fi_softap>` sections.
Setting the Passphrase
======================
``wapi psk`` command is used for setting the AP authentication security. Its
arguments are::
wapi psk <ifname> <passphrase> <index/flag> [wpa]
- ``<ifname>`` is the name of the interface set as Station Mode (STA);
- ``<passphrase>`` is the password. Its length depends on the authentication
algorithm. Please note that ``wapi psk`` command is also used to set auth
as open, but this parameter comes next, so it may be necessary to set a
"dummy" passphrase just to set auth to none;
- ``<index/flag>`` can be set numerically or textually, as follows:
- [0] WPA_ALG_NONE - to connect to an open AP;
- [1] WPA_ALG_WEP - to connect to a WEP-secured AP (not recommended);
- [2] WPA_ALG_TKIP - to use TKIP algorithm (not recommended);
- [3] WPA_ALG_CCMP - to use CCMP algorithm (recommended);
- ``[wpa]`` sets the WPA version (if applicable):
- [0] WPA_VER_NONE;
- [1] WPA_VER_1;
- [2] WPA_VER_2 (default, if not selected otherwise);
- [3] WPA_VER_3;
Setting the Network Name (ESSID)
================================
The name of the Wireless Network can be set using ``wapi essid`` command::
wapi essid <ifname> <essid> <index/flag>
- ``<ifname>`` is the name of the interface set as Station Mode (STA);
- ``<essid>`` is the name of the Wireless Network;
- ``<index/flag>`` selects whether to connect to the AP or not:
- [0] WAPI_ESSID_OFF - Don't connect to the AP;
- [1] WAPI_ESSID_ON - Connect to the AP indicated by the provided ESSID;
- [2] WAPI_ESSID_DELAY_ON - Delay AP connection;
Examples
========
Connecting to an Open Network
-----------------------------
::
wapi psk wlan0 mypasswd WPA_ALG_NONE
wapi essid wlan0 myssid WAPI_ESSID_ON
or, equivalently
::
wapi psk wlan0 mypasswd 0
wapi essid wlan0 myssid 1
Connecting to a WPA2-PSK Network
--------------------------------
::
wapi psk wlan0 mypasswd WPA_ALG_CCMP
wapi essid wlan0 myssid WAPI_ESSID_ON
or, equivalently:
::
wapi psk wlan0 mypasswd 3
wapi essid wlan0 myssid 1
Connecting to a WPA3-SAE Network
--------------------------------
::
wapi psk wlan0 mypasswd WPA_ALG_CCMP WPA_VER_3
wapi essid wlan0 myssid WAPI_ESSID_ON
or, equivalently:
::
wapi psk wlan0 mypasswd 3 3
wapi essid wlan0 myssid 1
Connecting to a Hidden (WPA2-PSK) Network
-----------------------------------------
::
wapi psk wlan0 mypasswd WPA_ALG_CCMP
wapi essid wlan0 myssid WAPI_ESSID_DELAY_ON
wapi ap wlan0 aa:bb:cc:dd:dd:ff
or, equivalently:
::
wapi psk wlan0 mypasswd 3
wapi essid wlan0 myssid 2
wapi ap wlan0 aa:bb:cc:dd:dd:ff
