Mar 21, 2012 - Get WiFi interface. Use either of the following to get the IP address of wlan0 (only if it is connected). You can try nslookup www.google.com and see what it reports for your server, but on my phone it reports 0.0.0.0 which.

Hello,

i am building a Relay controller via ESP8266Wifi, every thing works fine with no problem, but the issue is that every time i restart the ESP, a new IP address is assigned, i would like to know if it is possible to fix an IP address from the code and not from the router

the Code is

3m software download. /*

• This sketch demonstrates how to set up a simple HTTP-like server.
• The server will set a GPIO pin depending on the request
• http://server_ip/gpio/0 will set the GPIO2 low,
• http://server_ip/gpio/1 will set the GPIO2 high
• server_ip is the IP address of the ESP8266 module, will be
• printed to Serial when the module is connected.
