AutoConnectWithFSParametersAndCustomIP

[eXadra]

Dear all, Im trying to use this example of the WifiManager for my ESp8266 applications but I cannot use it with fixed ip. This example given does not work.

The code is just the code as is in the example.

If I comment _wifiManager.setSTAStaticIPConfig(_ip, _gw, sn); the module sets dhcp and everithing works fine. Thanks in advance.

I'm facing the same issue. After first boot, the device will boot its config portal, as expected. After setting up wifi it will give me a *WM: Already connected. Bailing out. but I can't reach the device (with a ping). After a reboot the device will boot its config portal again (and again, and again, ...).

If I use DHCP (by commenting the static configuration) all works as expected.
