WIfiManager on ESP32 is not working #22

Hi,

I am trying to run the Autoconnect example from the wifimanager esp32.

I am getting the following error:

I was having the same HTTP_HEAD problem and the solution was simpler than it looked. I just edited the WiFiManager.h files and WifiManager.cpp replacing (HTTP_HEAD) with (HTTP_HEADER) and there was no more compilation problem.

shahidare · 2018-11-05T10:40:54Z

I did that but then wifi manager was not functioning for me.

Do you using libraries WebServer and DNSServer the same autor?

https://github.com/zhouhan0126/DNSServer---esp32
Try it use this libraries together and see if working.
For me to be working perfectly.

Regards

For now I am using asyc version and it is working. ( other than wifi reset ) I did tired the usual hacks but it doesn’t seem to be working. I am using Mac for the arduino. I believe I have to try it with other machines as I can see it has worked for many people. Thank you for the help.

@lacneto
Thanks, It solved my problem

CraigH78 · 2019-02-01T15:48:23Z

@lacneto
HTTP_HEAD to HTTP_HEADER worked for me also. Thank you!

DaveCalaway · 2020-01-28T21:41:43Z

In the Arduino IDE i must edited the file "WiFiManager.h" as @lacneto said. But i don't understand why this appends.

In case someone uses Platform IO, you just edit the platformio.ini adding:

lib_deps =
  https://github.com/zhouhan0126/WIFIMANAGER-ESP32.git
  https://github.com/zhouhan0126/DNSServer---esp32.git
  https://github.com/zhouhan0126/WebServer-esp32.git

just add __ to the HTTP_HEAD[] variable in WifiManager.h and replace HTTP_HEAD to __HTTP_HEAD in WiFiManager.cpp. in arduino WifiManager library.

I was having the same HTTP_HEAD problem and the solution was simpler than it looked. I just edited the WiFiManager.h files and WifiManager.cpp replacing (HTTP_HEAD) with (HTTP_HEADER) and there was no more compilation problem.

Had to do this, also on an ESP8266, works now.

It is very useful!
thanks

After I did this it worked for me :)
