Does the CaptivePortal example work for you on either Android or IOS?

And do you have

Code: Select all#define DEBUG

uncommented in ESP8266WebServer.cpp? It's not especially verbose, but it'll show responses from the ESP in your serial console.

No, the captive portal example does not work on Android. Only iOS.
Oh good to know, about the DEBUG

EDIT:
For fun, I added some debugging in DNSServer.ccp to see what Android was doing as soon as it connects. This is what it spits out.

This repeats over and over and over...and the sickening thing is, I don't even have facebook apps installed. So why is Android even trying to contact facebook???

Also does not work in Windows

The google.com portion is when I opened my browser. I even typed in blah.com and nothing

- Mon Jun 22, 2015 10:15 pm #21310 Google and Facebook aka microsoft are all after your data as that is what they give the Governments of the world in return for the Governments buying microsoft products . So its probably built in and mostly hidden from you . You have just exposed it.

Your debug responses are super handy - are you grabbing that from replyWithIP? Mind sharing a code snip?

Also, have you tried plugging connectivitycheck.android.com into a server.on() test?

Code: Select allserver.on("connectivitycheck.android.com", handle_root);

Finally, I've been trying to figure out how to navigate Apple's CNA, and the one thing that consistently works is sending the word "Success" in the head of a message:

Code: Select all"<!DOCTYPE html><html><head><title>Success</title></head><body>"

I've read that Google uses a similar approach - might be worth a shot.
