I’ve not tried this software library, but I did have a quick look at the code.
My thoughts are this is where you define the custom fields that will appear in the captive portal, so in this case there would be fields allowing you to input a device name (presumably for OTA) and the Blynk server, port and Auth code.
So, as the OP said, this SHOULD work as it stands and you’ll then get captive portal fields to allow you to add your Blynk related credentials.
As I said, I’ve not tried it.
Pete.
Good morning @PeteKnight
as you know I am not a coder
after compiling the sketch I am receiving this error
In file included from C:\Users\------------\main.ino:19:0:
sketch\webpages.h: In function 'String saveDone(AutoConnectAux&, PageArgument&)':
webpages.h:150: error: cannot convert 'String' to 'AutoConnectAux*' in initialization
AutoConnectAux* blynk_setting = portal.where();
exit status 1
cannot convert 'String' to 'AutoConnectAux*' in initialization
I really don’t know what I am missing.
same error was posted here by @Brummer but no reply from @Nilava_Chowdhury
Not sure. As I said, I’ve never tried the software.
If I get chance I’ll give it a try later, but I’m quite busy at the moment 
The OP was last seen on 22nd April.
Pete.
I installed the libraries and tried to compile the code and get exactly the same error message.
Pete.
Sorry guys, i had been busy with my exams, i tried out the code, the issue is with the latest library, i need to make changes for the latest library, in the mean time you guys can try with arduino json v5 and it should work perfect!
@PeteKnight @Ze_Pico
Arduino Json V6 causes another error message. Downgrading to v5 eliminates that message, but then results in this compiler error:
error: cannot convert ‘String’ to ‘AutoConnectAux*’ in initialization
AutoConnectAux* blynk_setting = portal.where();
Pete.
Use AutoConnect library version 0.9.7
How can I use this with the ESP32 instead of the ESP8266? I am not that great at coding.
It compiles correctly when using v0.9.7
Pete.
According to the documentation, it should automatically detect that an ESP32 is being used.
Pete.
Phew! I will update my code to work with latest version when i have time. Or maybe it won’t be necessary when new blynk comes, let’s see what features will be made free for the community.
Yes the Library Worked with the ESP32 but I was referring to the Example Provided. Its written for the 8266.
Well, the example sketch contains this code:
// Adjusting WebServer class with between ESP8266 and ESP32.
ESP8266WebServer webServer;
AutoConnect portal(webServer);
AutoConnectConfig config;
I’ve not tried it with either an ESP8266 or ESP32, have you?
Pete.
Still getting another Error 
after
ArduinoJson v5
AutoConnect library version 0.9.7
sketch\filehandeling.h:4:2: error: expected initializer before 'bool'
bool saveConfiguration(const char *filename, const BlynkConfig &saveconfig) {`
but here what you get on the "Serial Monitor"
@Nilava_Chowdhury May be you should revise your code.

Yes there are warnings, but it should work, i will have to rewrite it from the beginning as the library changed quite a lot. I will try to rewrite and upload new code.
If you wanna try out yourself i mentioned the library link in the post you can see the examples in his repo.
Library - AutoConnect Library
yes, and I am using the AutoConnect library version 0.9.7 as you mentioned.
about the examples in the repo are a bit difficult for me because I am not programmer .
I will wait your new code.
thanks
The code compiled without warnings, but when uploaded the device gives constant WDT resets.
Pete.
Can we add the password for Wifi Manager?
ex: when we type the IP of the device it should authenticate before we select the SSID… this is for security purposes …
Any thoughts?
