===========
It is possible to use ESP32 as an Access Point (SoftAP). Actually there are some
boards with a ``sta_softap`` which enables this support.
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 wlan0 mypasswd 1
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``.
The ``dhcpd_start`` is necessary to let your board to associate an IP to your smartphone.
