-WebSocket Server and Client for Arduino [![Build Status](https://github.com/Links2004/arduinoWebSockets/actions/workflows/main.yml/badge.svg?branch=master)](https://github.com/Links2004/arduinoWebSockets/actions?query=branch%3Amaster)
+WebSocket Server and Client for Arduino
 ===========================================
 
 a WebSocket Server and Client for Arduino based on RFC6455.
 
-
+ 
 ##### Supported features of RFC6455 #####
  - text frame
  - binary frame
  - connection close
  - ping
  - pong
+ 
+##### Not supported features of RFC6455 #####
  - continuation frame
-
+  
 ##### Limitations #####
  - max input length is limited to the ram size and the ```WEBSOCKETS_MAX_DATA_SIZE``` define
  - max output length has no limit (the hardware is the limit)
  - Client send big frames with mask 0x00000000 (on AVR all frames)
- - continuation frame reassembly need to be handled in the application code
-
- ##### Limitations for Async #####
- - Functions called from within the context of the websocket event might not honor `yield()` and/or `delay()`.  See [this issue](https://github.com/Links2004/arduinoWebSockets/issues/58#issuecomment-192376395) for more info and a potential workaround.
- - wss / SSL is not possible.
 
 ##### Supported Hardware #####
- - ESP8266 [Arduino for ESP8266](https://github.com/esp8266/Arduino/)
- - ESP32 [Arduino for ESP32](https://github.com/espressif/arduino-esp32)
- - ESP31B
- - Raspberry Pi Pico W [Arduino for Pico](https://github.com/earlephilhower/arduino-pico)
- - Particle with STM32 ARM Cortex M3
- - ATmega328 with Ethernet Shield (ATmega branch)
- - ATmega328 with enc28j60 (ATmega branch)
- - ATmega2560 with Ethernet Shield (ATmega branch)
- - ATmega2560 with enc28j60 (ATmega branch)
- - Arduino UNO [R4 WiFi](https://github.com/arduino/ArduinoCore-renesas)
- - Arduino Nano 33 IoT, MKR WIFI 1010 (requires [WiFiNINA](https://github.com/arduino-libraries/WiFiNINA/) library)
- - Seeeduino XIAO, Seeeduino Wio Terminal (requires [rpcWiFi](https://github.com/Seeed-Studio/Seeed_Arduino_rpcWiFi) library)
-
-###### Note: ######
-
-  version 2.0.0 and up is not compatible with AVR/ATmega, check ATmega branch.
-
-  version 2.3.0 has API changes for the ESP8266 BareSSL (may brakes existing code)
-
-  Arduino for AVR not supports std namespace of c++.
-
+ - ESP8266 [Arduino for ESP8266](https://github.com/Links2004/Arduino)
+ - ATmega328 with Ethernet Shield (alpha)
+ - ATmega328 with enc28j60 (alpha)
+ - ATmega2560 with Ethernet Shield (alpha)
+ - ATmega2560 with enc28j60 (alpha)
+ 
 ### wss / SSL ###
  supported for:
  - wss client on the ESP8266
- - wss / SSL for ESP32 in client mode
- - wss / SSL is not natively supported in WebSocketsServer however it is possible to achieve secure websockets
-   by running the device behind an SSL proxy. See [Nginx](examples/Nginx/esp8266.ssl.reverse.proxy.conf) for a
-   sample Nginx server configuration file to enable this.
-
-### Root CA Cert Bundles for SSL/TLS connections ###
-
-Secure connections require the certificate of the server to be verified. One option is to provide a single certificate in the chain of trust. However, for flexibility and robustness, a certificate bundle is recommended. If a server changes the root CA from which it derives its certificates, this will not be a problem. With a single CA cert it will not connect.
-
- - For [technical details](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/protocols/esp_crt_bundle.html)
- - For a [PlatformIO setup](https://github.com/Duckle29/esp32-certBundle/)
- - For an [example](examples/esp32/WebSocketClientSSLBundle/)
-
-Including a bundle with all CA certs will use 77.2 kB but this list can be reduced to 16.5 kB for the 41 most common. This results in 90% absolute usage coverage and 99% market share coverage according to [W3Techs](https://w3techs.com/technologies/overview/ssl_certificate). The bundle is inserted into the compiled firmware. The bundle is not loaded into RAM, only its index.
-
-### ESP Async TCP ###
-
-This libary can run in Async TCP mode on the ESP.
-
-The mode can be activated in the ```WebSockets.h``` (see WEBSOCKETS_NETWORK_TYPE define).
-
-[ESPAsyncTCP](https://github.com/me-no-dev/ESPAsyncTCP) libary is required.
-
-
-### High Level Client API ###
-
- - `begin` : Initiate connection sequence to the websocket host.
-```c++
-void begin(const char *host, uint16_t port, const char * url = "/", const char * protocol = "arduino");
-void begin(String host, uint16_t port, String url = "/", String protocol = "arduino");
-```
- - `onEvent`: Callback to handle for websocket events
-
-```c++
- void onEvent(WebSocketClientEvent cbEvent);
-```
-
- - `WebSocketClientEvent`: Handler for websocket events
-```c++
- void (*WebSocketClientEvent)(WStype_t type, uint8_t * payload, size_t length)
-```
-Where `WStype_t type` is defined as:
-```c++
-  typedef enum {
-      WStype_ERROR,
-      WStype_DISCONNECTED,
-      WStype_CONNECTED,
-      WStype_TEXT,
-      WStype_BIN,
-      WStype_FRAGMENT_TEXT_START,
-      WStype_FRAGMENT_BIN_START,
-      WStype_FRAGMENT,
-      WStype_FRAGMENT_FIN,
-      WStype_PING,
-      WStype_PONG,
-  } WStype_t;
-```

-This is a PlatformIO project that uses a modified WiFiClientSecure library (in `lib`) to 
-implement proper SSL support using root certificates as discussed 
-[here](https://github.com/espressif/arduino-esp32/issues/3646#issuecomment-648292677)
-
-It is based on the work by [meltdonw03](https://github.com/meltdown03) in that thread, and the
-[BasicHttpsClient example](https://github.com/espressif/arduino-esp32/blob/1.0.4/libraries/HTTPClient/examples/BasicHttpsClient/BasicHttpsClient.ino) from the arduino-esp32 project.
-
-Just copy `include/secrets.hpp.template` to `include/secrets.hpp` and fill in your WiFi details.
-Then it should be pretty much ready to go. The local WiFiClientSecure library should take priority.
-Debug is set to verbose, so you'll see a lot of noise, but there should also be this readme on success :)
-
-To get a current CA cert bundle download it from [curl's website](https://curl.se/docs/caextract.html).

-## Minimal example of WebsocketClientOTA and Python server
-
-Take this as small example, how achieve OTA update on ESP8266 and ESP32.
-
-Python server was wrote from train so take it only as bare example.
-It's working, but it's not mean to run in production.
-
-
-### Usage:
-
-Start server:
-```bash
-cd python_ota_server
-python3 -m venv .venv
-source .venv/bin/activate
-pip3 install -r requirements.txt
-python3 main.py
-```
-
-Flash ESP with example sketch and start it.
-
-Change version inside example sketch to higher and compile it and save it to bin file.
-
-Rename it to `mydevice-1.0.1-esp8266.bin` and place it inside new folder firmware (server create it).
-
-When the ESP connect to server, it check if version flashed is equal to fw in firmware folder. If higher FW version is present,
-start the flash process.
