make the ESP an AP and disable DHCP

[odaiayoob]

Hello,

I need to use the esp as wifi extender or access point, without DHCP, how can i do that ? i need to disable DHCP and set static IP, GW, subnet and DNS, then all IPs come from main DHCP

Currently you cannot disable the DHCP server, but bou are free to choose static IPs in the APs subnet.

As the esp_wifi_repeater is in fact a (NAT-)Router, a central DHCP server won't work. Each AP has to span its own subnet and DHCP broadcast requests are not even forwarded across router boundaries.

Is it possible to add a new feature to disable DHCP server? if it's possible, Can you tell me where to start?

[martin-ger]

If you can compile the sources with the esp-open-sdk, you can simply add a wifi_softap_dhcps_stop() after line 3688 in user_main.c.

But as said before: you can use static IPs in AP subnets even without modification: the DHCP server only assigns addresses in the range from 2-128. Anything from 129-254 is free for static assigned IPs.

I believe that odaiayoob mean to use IP in the same subnet of main DHCP.

@zoomx Correct,

I need to make my ESP an access point only and I need to set fixed IP for it from main DHCP, and any device connected to this Access point get the IP from main DHCP,

I just read this post, after write a new issue... i want to do the same thing.. use only my main dhcp and disable esp dhcp...

[geofrancis]

what your wanting is a transparent bridge mode so the extender is invisible on the network not doing nat.

[martin-ger]

Transparent bridge does not work, sorry.
