Fixing IP Address for ESP32 and PC Communication

Postby e2738729 » Tue Mar 26, 2019 7:20 pm

Hi everyone,

I am not very good at network programming so I hope that someone could give me some directions to try.

I have a PC communicate with ESP32 via TCP/IP. The ESP32 is a server and PC is a client. As you already know, the PC requires the ESP32's IP address and port in order to establish a connection with the ESP32.

My biggest problem is that the ESP32's IP address is not fixed. First day I have "192.168.1.4", but now it is "192.168.1.3" What should I do about this? I dont want to change my python code on PC every time the IP address of the ESP32 changes.

Thanks

This is not a hardware question; moved to General Discussion.

hello,

its simple
Connect to your router at 192.168.1.1 (This is for my router) check the ip on your router backside.

there goto DHCP reserved.

Assign a IP along with mac..Thats it..

Thanks for your reply arunbm,

So just to clarify,

"there goto DHCP reserved.
Assign a IP along with mac..Thats it.."

I will do the above two steps on the router website right? Each router whenever I setup requires a website that I can log-in, setup the wifi name and password.

Thanks

Yes, it is a function of the router supplying the DHCP addresses. There should be a setup page to fix a DHCP IP to a MAC address.
