Hello everybody
first sorry if my english is not correct :)
I have a question I block on a problem
I would like my IP to be fixed, knowing that I do not know the gateway address, it changes depending on the box where we are connected, it can go from 192.168.1.1 and 192.168.1.254

I use the function wifiManager.setAPStaticIPConfig(int, int , int);
this indicates that I already know my gateway address which is not my case since we connect to several different gateways

my question is the following how to fix the IP without knowing the gateway knowing that it changes according to the box where we are connected

Thank you in advance for your answers ! :)
sorry for my english it is not correct
PS thanks to Google Translate lol

Hello @gauix4 . Sorry for the confusion. My post was not much of a response, but rather
a confirmation that I too am hitting the issue you are describing here. So I thought of posting my findings here instead of opening a duplicate.

I have an ESP32, not an ESP8266 when hitting this. It is very possible that it does not matter which one is used. The code I'm using to reproduce this issue uses Preferences which I think does not exist in ESP8266. But, that is irrelevant to the issue here.

Hope this makes it a little clearer.

Best,

I mean what you are asking makes no sense. How can you connect to something you dont know.. do you want to connect via dhcp the first time then change to static afterwards? Then you can jusy use esp function to get gateway.

if that is useful because i don't know this ip address
my little box is made to go to several houses so the address will not be the same
in my house I know it's 192.168.1.254 but in the other houses I don't know it's not necessarily the same
and my little box communicates with another one so if the IP address is not identical they cannot communicate

I mean if you are connecting to different networks you cannot just use any ip address, it has to be on the same subnet as the gateway. You have to use dhcp.

Maybe I misunderstood, you want the AP to be static ?
Then the gateway is whatever you want it to be, its your network and only exists on the esp

you keep saying connect to , but in ap mode you connect to the esp .. in sta mode the esp connects to a network. So I am confused as to what you are doing.

no actually when i use wifimanager i can't assign a fixed IP address for my server
let me explain
I use wifimanager to create an access point so that the person goes on it and connects to this internet box
until then everything is OK
I also do the same manipulation with the second box
now they are both connected to the same internet box
the problem is that boxing assign an IP address and in my code I can not know in advance so impossible to communicate with the two boxes
so I have to fix their IP address so that it can communicate

IPAddress server(192,168,1,80);
serveur.begin();

i tried putting this in a code it works fine but when i call wifi manager it doesn't work anymore

They should be able to communicate on the same network as dhcp will give them the gateway, thats how it works.

When you say box you mean 2 esp and 1 router?

yes I understood correctly but you must know the IP address of each ESP connect
and when i use wifimanager i can't fix the ip after connecting to the paserel
therefore the gateway assigns an IP address to each ESP which does not correspond to this indicate in the program so it does not communicate together

to fix IP address I would need to know the gateway address
except that I don't know her

You could use mdns and host names also

I would after connecting, get the gateway and then set the static ip after connected

WiFi.gatewayIP().toString()

Of course other networks might not be 192 subnet there are others
