Wi-Fi
-----
.. tip:: Boards usually expose a ``wapi`` defconfig which enables Wi-Fi
A standard network interface will be configured and can be initialized such as::
nsh> ifup wlan0
nsh> wapi psk wlan0 mypasswd 3
nsh> wapi essid wlan0 myssid 1
nsh> renew wlan0
In this case a connection to AP with SSID ``myssid`` is done, using ``mypasswd`` as
password. IP address is obtained via DHCP using ``renew`` command. You can check
the result by running ``ifconfig`` afterwards.
Wi-Fi SoftAP
------------
It is possible to use ESP32 as an Access Point (SoftAP).
.. tip:: Boards usually expose a ``sta_softap`` defconfig which enables Wi-Fi
(STA + SoftAP)
If you are using this board config profile you can run these commands to be able
to connect your smartphone or laptop to your board::
nsh> ifup wlan1
nsh> dhcpd_start wlan1
nsh> wapi psk wlan1 mypasswd 3
nsh> wapi essid wlan1 nuttxap 1
In this case, you are creating the access point ``nuttxapp`` in your board and to
connect to it on your smartphone you will be required to type the password ``mypasswd``
using WPA2.
The ``dhcpd_start`` is necessary to let your board to associate an IP to your smartphone.
