|
||||
Where x and y are the last two numbers of the IP that your router gave to
|
||||
your board.
|
||||
|
||||
wifishare
|
||||
---------
|
||||
|
||||
The ``wifishare`` let your ESP32 board to work as Access Point (WiFi Router)
|
||||
and WiFi Station at same time. This way your board will connect to a real
|
||||
WiFi Router (from your ISP for example) and will offer WiFi connection to other
|
||||
devices and share WiFi connection with them.
|
||||
|
||||
After configuring the ``esp32-devkit:wifishare`` you need to define your
|
||||
credentials in the menuconfig. You can define your credentials this way::
|
||||
|
||||
$ make menuconfig
|
||||
-> Application Configuration
|
||||
-> Network Utilities
|
||||
-> Network initialization (NETUTILS_NETINIT [=y])
|
||||
-> WAPI Configuration
|
||||
|
||||
After compile and flash your board you need to confirm you have two interfaces:
|
||||
|
||||
nsh> ifconfig
|
||||
wlan0 Link encap:Ethernet HWaddr bc:dd:c2:d4:a9:ec at RUNNING mtu 1504
|
||||
inet addr:192.168.0.7 DRaddr:192.168.0.1 Mask:255.255.255.0
|
||||
|
||||
wlan1 Link encap:Ethernet HWaddr bc:dd:c2:d4:a9:ed at DOWN mtu 1504
|
||||
inet addr:0.0.0.0 DRaddr:0.0.0.0 Mask:0.0.0.0
|
||||
|
||||
Now you need to configure your wlan1 to become a WiFi Access Point:
|
||||
|
||||
nsh> dhcpd_start wlan1
|
||||
nsh> wapi psk wlan1 mypasswd 3
|
||||
nsh> wapi essid wlan1 nuttxap 1
|
||||
|
||||
And you need to make the route to your WiFi Router (i.e. 192.168.0.1) the default route:
|
||||
|
||||
nsh> addroute default 192.168.0.1 wlan0
|
||||
nsh> route
|
||||
SEQ TARGET NETMASK ROUTER
|
||||
1. 0.0.0.0 0.0.0.0 192.168.0.1
|
||||
|
||||
Finally we will setup an iptables rule to NAT the wlan0 interface:
|
||||
|
||||
nsh> iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
|
||||
|
||||
After connectig a client (i.e. Linux computer) to the `nuttxap` Access Point
|
||||
you can confirm it is working this way:
|
||||
|
||||
$ ifconfig
|
||||

|
||||

That is it. You can use this 8.8.8.8 as DNS to resolve names.
