Description
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
/*
- 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.
