CaptiveIntraweb

A very simple, esp8266 based standalone captive-portal-like, access point serving local files only. This turns an ESP-01 module into an autonomous WiFi throwie.

Although the English release is currently ahead of the German version, you can use the html files of the German verion in the new English release.

Description: This project (apart from the code here) only requires an ESP-01 module, slightly modified NodeMCU firmware and a (rechargeable?) battery. Once running, the ESP-01 acts as an access-point, offering unencrypted access. I have added the firmware to the release packages, as the dev-environment now should all be open source / MIT licensed.

All DNS-requests are answered with the module's IP (192.168.4.1) The HTTP-request is parsed and one of the locally stored html pages is sent to the client.

Rel03 comes with a vastly improved startup procedure (init.lua). Not all files may fit on your module, especially if flash size is only 512kByte. Leave out the PDF and MP3 files to resolve that.

ESPlorer instructions

Hi, relatively new to NodeMCU and Lua.
I am trying to get your project working on my Wemos d1 mini. But I'm having problems uploading the stuff to the ESP using ESPlorer.

this is what i get after sending the lua files to the chip

Android captive portal detection causes reload

Android seems to send empty requests. These cause the module to reset.
server.lua needs input sanitation.

AP channel set

Hi there, first I have to thank you for the excellent work, doing very usefull function in captive mode.
I recently tried to set channel in cfg{} but nothing worked so far. Tried even beaconing time but don't have a working method to test if it works.
Is it because included nodemcu (rel3eng) is an old version?
Installing a recent clean Nodemcu without your modifications is going to work?
Thanks a lot in advance

Instructions request

Hello, where i can get the modified NodeMCU, or what i need to modify?

Thank you very much.

Available under GPLv3?

Hi! I'm wondering if you'd be willing to dual-license the file dns-liar.lua under GPLv3 in addition to the current GPLv2 license? We're interested in using it for our community network https://peoplesopen.net/ :)

Questions about Captive Intraweb

Hi Andreas, thanks for sharing your captive portal code, I have a few questions about getting this up and running. I think that I need your advice on where to get the correct NodeMCU binary to run the code under. Thanks. My email is [email protected]
