**1) SUMMARY**
This example implements a **captive portal** with library DNSServer, ie web page which opens automatically when user connects Wifi network (eg "PsychitHttp").
Captiveportal is implemented in **ESPAsyncWebServer** [https://github.com/me-no-dev/ESPAsyncWebServer/blob/master/examples/CaptivePortal/CaptivePortal.ino](url) and in **arduino-esp32 examples** [https://github.com/espressif/arduino-esp32/blob/master/libraries/DNSServer/examples/CaptivePortal/CaptivePortal.ino](url)
This feature can be implemented with Psychichttp with a **dedicated handler**, as shown in code below.
Code highlights are added below for reference.
**2) CODE**
**Definitions**
```
// captiveportal
// credits https://github.com/me-no-dev/ESPAsyncWebServer/blob/master/examples/CaptivePortal/CaptivePortal.ino
//https://github.com/espressif/arduino-esp32/blob/master/libraries/DNSServer/examples/CaptivePortal/CaptivePortal.ino
#include <DNSServer.h>
DNSServer dnsServer;
class CaptiveRequestHandler : public PsychicWebHandler { // handler
public:
CaptiveRequestHandler() {};
virtual ~CaptiveRequestHandler() {};
bool canHandle(PsychicRequest*request){
// ... if needed some tests ... return(false);
return true; // activate captive portal
}
esp_err_t handleRequest(PsychicRequest *request) {
//PsychicFileResponse response(request, LittleFS, "/captiveportal.html"); // uncomment : for captive portal page, if any, eg "captiveportal.html"
//return response.send(); // uncomment : return captive portal page
return request->reply(200,"text/html","Welcome to captive portal !"); // simple text, comment if captive portal page
}
};
CaptiveRequestHandler *captivehandler=NULL; // handler for captive portal
```
**setup()**
```
// captive portal
dnsServer.start(53, "*", WiFi.softAPIP()); // DNS requests are executed over port 53 (standard)
captivehandler= new CaptiveRequestHandler(); // create captive portal handler, important : after server.on since handlers are triggered on a first created/first trigerred basis
server.addHandler(captivehandler); // captive portal handler (last handler)
```
**loop()**
```
dnsServer.processNextRequest(); // captive portal
```
**3) RESULT**
**Access Point (web page is opened automatically when connecting to PsychicHttp AP)**
![captive portal access point](images/accesspoint.png)
**Station (web page is shown whatever url for Station IP, eg 192.168.1.50/abcdefg**

**OTA update example for PsychicHttp**
Example of OTA (Over The Air) update implementation for PsychicHttp, using Arduino IDE.
**Requirements**
Requirements for project are :
- OTA update for code (firmware)
- OTA update for data (littlefs)
- manual restart of ESP32, triggered by User (no automatic restart after code or data file upload)
**Implementation**
OTA update relies on handler PsychicUploadHandler.
Screenshots and Code are shown below.
**Credits**
https://github.com/hoeken/PsychicHttp/blob/master/src/PsychicUploadHandler.cpp
https://github.com/hoeken/PsychicHttp/issues/30
**Configuration**
Example has been implemented with following configuration :\
Arduino IDE 1.8.19\
arduino-32 v2.0.15\
PsychicHttp 1.1.1\
ESP32S3
**Example Files Structure**
```
arduino_ota
data
| update.html
arduino_ota.ino
code.bin
littlefs.bin
README
```
"code.bin" and "littlefs.bin" are example update files which can be used to update respectily code (firmware) or data (littlefs).
"Real" update files can be generated on Arduino IDE 1.x :
- for code, menu "Sketch -> Export bin"
- for data, using plugin arduino-esp32fs-plugin https://github.com/lorol/arduino-esp32fs-plugin/releases

This directory is intended for project header files.
A header file is a file containing C declarations and macro definitions
to be shared between several project source files. You request the use of a
header file in your project source file (C, C++, etc) located in `src` folder
by including it, with the C preprocessing directive `#include'.
```src/main.c
#include "header.h"
int main (void)
{
...
}
```
Including a header file produces the same results as copying the header file
into each source file that needs it. Such copying would be time-consuming
and error-prone. With a header file, the related declarations appear
in only one place. If they need to be changed, they can be changed in one
place, and programs that include the header file will automatically use the
new version when next recompiled. The header file eliminates the labor of
finding and changing all the copies as well as the risk that a failure to
find one copy will result in inconsistencies within a program.
In C, the usual convention is to give header files names that end with `.h'.
It is most portable to use only letters, digits, dashes, and underscores in
header file names, and at most one dot.

This directory is intended for project specific (private) libraries.
PlatformIO will compile them to static libraries and link into executable file.
The source code of each library should be placed in a an own separate directory
("lib/your_library_name/[here are source files]").
For example, see a structure of the following two libraries `Foo` and `Bar`:
|--lib

This directory is intended for project header files.
A header file is a file containing C declarations and macro definitions
to be shared between several project source files. You request the use of a
header file in your project source file (C, C++, etc) located in `src` folder
by including it, with the C preprocessing directive `#include'.
```src/main.c
#include "header.h"
int main (void)
{
...
}
```
Including a header file produces the same results as copying the header file
into each source file that needs it. Such copying would be time-consuming
and error-prone. With a header file, the related declarations appear
in only one place. If they need to be changed, they can be changed in one
place, and programs that include the header file will automatically use the
new version when next recompiled. The header file eliminates the labor of
finding and changing all the copies as well as the risk that a failure to
find one copy will result in inconsistencies within a program.
In C, the usual convention is to give header files names that end with `.h'.
It is most portable to use only letters, digits, dashes, and underscores in
header file names, and at most one dot.

This directory is intended for PIO Unit Testing and project tests.
Unit Testing is a software testing method by which individual units of
source code, sets of one or more MCU program modules together with associated
control data, usage procedures, and operating procedures, are tested to
determine whether they are fit for use. Unit testing finds problems early
in the development cycle.

This directory is intended for project header files.
A header file is a file containing C declarations and macro definitions
to be shared between several project source files. You request the use of a
header file in your project source file (C, C++, etc) located in `src` folder
by including it, with the C preprocessing directive `#include'.
```src/main.c
#include "header.h"
int main (void)
{
...
}
```
Including a header file produces the same results as copying the header file
into each source file that needs it. Such copying would be time-consuming
and error-prone. With a header file, the related declarations appear
in only one place. If they need to be changed, they can be changed in one
place, and programs that include the header file will automatically use the
new version when next recompiled. The header file eliminates the labor of
finding and changing all the copies as well as the risk that a failure to
find one copy will result in inconsistencies within a program.
In C, the usual convention is to give header files names that end with `.h'.
It is most portable to use only letters, digits, dashes, and underscores in
header file names, and at most one dot.
Read more about using header files in official GCC documentation:
* Include Syntax
* Include Operation
* Once-Only Headers
* Computed Includes

This directory is intended for project specific (private) libraries.
PlatformIO will compile them to static libraries and link into executable file.
The source code of each library should be placed in a an own separate directory
("lib/your_library_name/[here are source files]").
For example, see a structure of the following two libraries `Foo` and `Bar`:
|--lib
| |
| |--Bar
| | |--docs
| | |--examples
| | |--src
| | |- Bar.c
| | |- Bar.h
| | |- library.json (optional, custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html
| |
| |--Foo
| | |- Foo.c
| | |- Foo.h
| |
| |- README --> THIS FILE
|
|- platformio.ini
|--src
|- main.c
and a contents of `src/main.c`:
```
#include <Foo.h>
#include <Bar.h>
int main (void)
{
...
}
```
PlatformIO Library Dependency Finder will find automatically dependent
libraries scanning project source files.

This directory is intended for PIO Unit Testing and project tests.
Unit Testing is a software testing method by which individual units of
source code, sets of one or more MCU program modules together with associated
control data, usage procedures, and operating procedures, are tested to
determine whether they are fit for use. Unit testing finds problems early
in the development cycle.

This directory is intended for project header files.
A header file is a file containing C declarations and macro definitions
to be shared between several project source files. You request the use of a
header file in your project source file (C, C++, etc) located in `src` folder
by including it, with the C preprocessing directive `#include'.
```src/main.c
#include "header.h"
int main (void)
{
...
}
```
Including a header file produces the same results as copying the header file
into each source file that needs it. Such copying would be time-consuming
and error-prone. With a header file, the related declarations appear
in only one place. If they need to be changed, they can be changed in one
place, and programs that include the header file will automatically use the
new version when next recompiled. The header file eliminates the labor of
finding and changing all the copies as well as the risk that a failure to
find one copy will result in inconsistencies within a program.
In C, the usual convention is to give header files names that end with `.h'.
It is most portable to use only letters, digits, dashes, and underscores in
header file names, and at most one dot.
Read more about using header files in official GCC documentation:
* Include Syntax
* Include Operation
* Once-Only Headers
* Computed Includes
https://gcc.gnu.org/onlinedocs/cpp/Header-Files.html

This directory is intended for project specific (private) libraries.
PlatformIO will compile them to static libraries and link into executable file.
The source code of each library should be placed in a an own separate directory
("lib/your_library_name/[here are source files]").
For example, see a structure of the following two libraries `Foo` and `Bar`:
|--lib

This directory is intended for PIO Unit Testing and project tests.
Unit Testing is a software testing method by which individual units of
source code, sets of one or more MCU program modules together with associated
control data, usage procedures, and operating procedures, are tested to
determine whether they are fit for use. Unit testing finds problems early
in the development cycle.

This directory is intended for project header files.
A header file is a file containing C declarations and macro definitions
to be shared between several project source files. You request the use of a
header file in your project source file (C, C++, etc) located in `src` folder
by including it, with the C preprocessing directive `#include'.
```src/main.c
#include "header.h"
int main (void)
{
...
}
```
Including a header file produces the same results as copying the header file
into each source file that needs it. Such copying would be time-consuming
and error-prone. With a header file, the related declarations appear
in only one place. If they need to be changed, they can be changed in one
place, and programs that include the header file will automatically use the
new version when next recompiled. The header file eliminates the labor of
finding and changing all the copies as well as the risk that a failure to
find one copy will result in inconsistencies within a program.
In C, the usual convention is to give header files names that end with `.h'.
It is most portable to use only letters, digits, dashes, and underscores in
header file names, and at most one dot.
Read more about using header files in official GCC documentation:
* Include Syntax
* Include Operation
* Once-Only Headers
* Computed Includes

This directory is intended for PlatformIO Test Runner and project tests.
Unit Testing is a software testing method by which individual units of
source code, sets of one or more MCU program modules together with associated
control data, usage procedures, and operating procedures, are tested to
determine whether they are fit for use. Unit testing finds problems early
in the development cycle.

This directory is intended for project header files.
A header file is a file containing C declarations and macro definitions
to be shared between several project source files. You request the use of a
header file in your project source file (C, C++, etc) located in `src` folder
by including it, with the C preprocessing directive `#include'.
```src/main.c
#include "header.h"
int main (void)
{
...
}
```
Including a header file produces the same results as copying the header file
into each source file that needs it. Such copying would be time-consuming
and error-prone. With a header file, the related declarations appear
in only one place. If they need to be changed, they can be changed in one
place, and programs that include the header file will automatically use the
new version when next recompiled. The header file eliminates the labor of
finding and changing all the copies as well as the risk that a failure to
find one copy will result in inconsistencies within a program.
In C, the usual convention is to give header files names that end with `.h'.
It is most portable to use only letters, digits, dashes, and underscores in
header file names, and at most one dot.
Read more about using header files in official GCC documentation:
* Include Syntax
* Include Operation
* Once-Only Headers
* Computed Includes

This directory is intended for project specific (private) libraries.
PlatformIO will compile them to static libraries and link into executable file.
The source code of each library should be placed in a an own separate directory
("lib/your_library_name/[here are source files]").
For example, see a structure of the following two libraries `Foo` and `Bar`:
|--lib

This directory is intended for PlatformIO Test Runner and project tests.
Unit Testing is a software testing method by which individual units of
source code, sets of one or more MCU program modules together with associated
control data, usage procedures, and operating procedures, are tested to
determine whether they are fit for use. Unit testing finds problems early
in the development cycle.
