 ASIO port
 =========

-Overview
--------
 Asio is a cross-platform C++ library, see https://think-async.com/Asio/. It provides a consistent asynchronous model using a modern C++ approach.

+The ESP-IDF component `ASIO` has been moved from ESP-IDF since version v5.0 to a separate repository:

-ASIO documentation
-^^^^^^^^^^^^^^^^^^
-Please refer to the original asio documentation at https://think-async.com/Asio/Documentation.
-Asio also comes with a number of examples which could be find under Documentation/Examples on that web site.
+* `ASIO component on GitHub <https://github.com/espressif/esp-protocols/components/asio>`__

-Supported features
-^^^^^^^^^^^^^^^^^^
-ESP platform port currently supports only network asynchronous socket operations; does not support serial port.
-SSL/TLS support is disabled by default and could be enabled in component configuration menu by choosing TLS library from
+Hosted Documentation
+--------------------

- mbedTLS with OpenSSL translation layer (default option)
- wolfSSL
+The documentation can be found on the link below:

-SSL support is very basic at this stage and it does include following features:
-
- Verification callbacks
- DH property files
- Certificates/private keys file APIs
-
-Internal asio settings for ESP include
-
- EXCEPTIONS are enabled in ASIO if enabled in menuconfig
- TYPEID is enabled in ASIO if enabled in menuconfig
-
-Application Example
-------------------
-ESP examples are based on standard asio :example:`protocols/asio`:
-
- :example:`protocols/asio/udp_echo_server`
- :example:`protocols/asio/tcp_echo_server`
- :example:`protocols/asio/asio_chat`
- :example:`protocols/asio/ssl_client_server`
-
-Please refer to the specific example README.md for details

 -------

 `ESP-BSP <https://github.com/espressif/esp-bsp>`_ repository contains Board Support Packages (BSPs) for various Espressif's and 3rd party development boards. BSPs are useful for quick start on a supported board. Usually they contain pinout definition and helper functions, that will initialize peripherals for the specific board. Additionally, the BSP would contain drivers for external chips populated on the development board, such as sensors, displays, audio codecs etc.

-# Asio chat client and server examples
-
-(See the README.md file in the upper level 'examples' directory for more information about examples.)
-
-The application aims to demonstrate a simple use of Asio library in different modes.
-In project settings it could be configured to run either a Asio chat server, a Asio chat client, or both.
-
-## How to use example
-
-The example is configured by default as an Asio chat client.
-
-Note that the example uses string representation of IP addresses and ports.
-
-You can find the upstream asio chat implementation [here] https://github.com/chriskohlhoff/asio/tree/master/asio/src/examples/cpp11/chat
-
-### Asio Client
-
-In the client mode, the example connects to the configured address, sends the message, which was inserted as an input in the terminal, and receives a response.
-
-### Asio Server
-
-In the server mode, Asio chat server with a specified port number is created and being polled till a connection request from the client arrives.
-Chat server echoes a message (received from any client) to all connected clients.
-
-## Configure the project
-
-```
-idf.py menuconfig
-```
-
-Set following parameters under Example Configuration Options:
-
-* Set `EXAMPLE_CHAT_SERVER` to use the example as an ASIO chat server
-    * Configure `EXAMPLE_CHAT_SERVER_BIND_PORT` to the port number.
-
-* Set `EXAMPLE_CHAT_CLIENT` to use the example as an ASIO chat client
-    * Configure `EXAMPLE_CHAT_CLIENT_CONNECT_ADDRESS` to a string representation of the address to connect the client to.
-    * Configure `EXAMPLE_CHAT_CLIENT_CONNECT_PORT` to the port number.
-
-* Configure Wi-Fi or Ethernet under "Example Connection Configuration" menu. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../../README.md) for more d    etails.
-
-## Running the example in server mode
-
- Configure the example according "Configure the project" section.
- Run `idf.py -p PORT flash monitor` to build and upload the example to your board and connect to it's serial terminal.
- Wait for the board to connect to WiFi or Ethernet (note the IP address).
- Connect to the server using multiple clients, for example using any option below.
-    - build and run asio chat client on your host machine
-    - run chat_client asio example on ESP platform
-    - since chat messages consists of ASCII size and message, it is possible to
-        netcat `nc IP PORT` and type for example ` 4ABC<CR>` to transmit 'ABC\n'
-
-## Running the example in client mode
-
- Configure the example according "Configure the project" section.
- Start chat server either on host machine or as another ESP device running chat_server example.
- Run `idf.py -p PORT flash monitor` to build and upload the example to your board and connect to it's serial terminal.
- Wait for the board to connect to WiFi or Ethernet.
- Receive and send messages to/from other clients on stdin/stdout via serial terminal.
-
-See the README.md file in the upper level 'examples' directory for more information about examples.

-# Async request using ASIO
-
-(See the README.md file in the upper level 'examples' directory for more information about examples.)
-
-The application aims to show how to compose async operations using ASIO to build network protocols and operations.
-
-# Configure and Building example
-
-This example doesn't require any configuration, just build it with 
-
-```
-idf.py build
-```
-
-# Async operations composition and automatic lifetime control
-
-On this example we compose the operation by starting the next step in the chain inside the completion handler of the 
-previous operation. Also we pass the `Connection` class itself as the parameter of its final handler to be owned by 
-the following operation. This is possible due to the control of lifetime by the usage of `std::shared_ptr`.
-
-The control of lifetime of the class, done by `std::shared_ptr` usage, guarantee that the data will be available for 
-async operations until it's not needed any more. This makes necessary that all of the async operation class must start 
-its lifetime as a `std::shared_ptr` due to the usage of `std::enable_shared_from_this`.
-

-# Configure and Building example
-
-This example requires the proxy address to be configured. You can do this using the menuconfig option.
-Proxy address and port must be configured in order for this example to work. 
-
-If using Linux ssh can be used as a proxy for testing. 
-
-```
-ssh -N -v -D 0.0.0.0:1080 localhost
-```
-# Async operations composition and automatic lifetime control
-
-For documentation about the structure of this example look into [async\_request README](../async_request/README.md).

-# Asio SSL client/server example
-
-Simple Asio client and server with SSL/TLS transport
-
-## How to Use Example
-
-### Hardware Required
-
-This example can be executed on any ESP platform board. No external connection is required, it is recommended though
-to connect to internet or a local network via WiFi or Ethernet to easily exercise features of this example.
-
-### Configure the project
-
-* Open the project configuration menu (`idf.py menuconfig`)
-* Configure Wi-Fi or Ethernet under "Example Connection Configuration" menu. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../../README.md) for more details.
-* Enable the ASIO client and set server's host name to examine client's functionality.
-The ASIO client connects to the configured server and sends default payload string "GET / HTTP/1.1"
-* Enable the ASIO server to examine server's functionality. The ASIO server listens to connection and echos back what was received.
-
-### Build and Flash

-Build the project and flash it to the board, then run monitor tool to view serial output:
-
-```
-idf.py -p PORT flash monitor
-```
-
-(To exit the serial monitor, type ``Ctrl-]``.)
-
-See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.

-# Asio TCP echo server example
-
-Simple Asio TCP echo server using WiFi STA or Ethernet.
-
-## Example workflow
-
- Wi-Fi or Ethernet connection is established, and IP address is obtained.
- Asio TCP server is started on port number defined through the project configuration.
- Server receives and echoes back messages transmitted from client.
-
-## Running the example
-
- Open the project configuration menu (`idf.py menuconfig`) to configure Wi-Fi or Ethernet. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../../README.md) for more details.
- Set server port number in menuconfig, "Example configuration".
- Run `idf.py -p PORT flash monitor` to build and upload the example to your board and connect to it's serial terminal.
- Wait for the board to connect to WiFi or Ethernet (note the IP address).
- You can now send a TCP message and check it is repeated, for example using netcat `nc IP PORT`.
-
-See the README.md file in the upper level 'examples' directory for more information about examples.
