Unable to set fixed IP add on ESP32

[zenonmb]

Colleagues,

I was happily running opensprinkler on ESP32 until I decided to switch to fixed IP add . Accesed the GUI, under options, uncheck DHCP. It showed existing IP and changed to the one I wanted (fixed) and did save changes .Never came up….

Since there was not any activity on serial monitor, decided to flash again (the ESP32,using Arduino 1.8.19) . Somehow did no erase completely the flash, since the system is continously rebooting.

So, to recover the esp32, I had to flash it again , but now using esp tool (not arduino)and then is back again , but using DHCP . And if I change the DHCP to fixed, same situation….

Anyone seeing this behavior?
Anyone running ESP32 on fixed IP add?

Have you tried using the DHCP reservation feature on your router to set a fixed IP?

[zenonmb]

No,I have not . But what would change that on the controller? Actually, at home I have all DHCP . Are you saying that the router might be “kicking off” the controller and this casues the reboot? I can see and checked that the IP address is not in use.
On the field, yes I have some range reserved for DHCP

[Ray]

If your router can do DHCP reservation, then why would you need to set static IP on the controller? You want a fixed IP, and DHCP reservation can achieve that, so you can keep Opensprinkler in DHCP mode. Your problem was due to setting DHCP off, isn’t it? What I was suggesting is a way to get fixed IP without having to set DHCP off.

[zenonmb]

My mistake. Was not aware of that feature in routers. Actually not sure if available .Will check . I thought you were talking about setting aside a range of IP addresses for dhcp (leaving other ip range for fixed ip), that every router ask when you define dhcp.
And yes,my problem was on setting DHCP to off.
