Simple library for WebSocket communication with ESP-WROOM-02(ESP8266) and smartphone browser.
This requires the Arduino core for ESP8266 WiFi chip library.

This use SD card (SPI).

Greatly improved handshake function composition.
Added a function to GET Web articles by https (SSL).
Along with that, include WiFiClientSecure.h.
Significant improvement of sample sketch.
Other minor fixes.
　　 -NEW Class-
EWS_HandShake_main
Get_Http_Req_Status
EWS_https_Web_Get
(Attention !: Consumes a lot of memory.)

I added a function that can divide the Websocket header file and include the automatically acquired local IP address.
EWS_Dev_AutoLIP_HandShake

A watchdog timer of ESP8266 to create a grace period to operate, has been added here and there yield ().
As a result, I think the operation is stable. Sample sketch also has been corrected.

-NEW class-
EWS_BrowserReceiveTextTag2
EWS_Status_Text2
EWS_WebSocket_Reconnection_Button2
EWS_Close_Button2
EWS_Window_ReLoad_Button2

Fixed ESP8266DataReceive_SD_write class.

*Upgraded EasyWebSocket beta 1.39 library.
Bug fix etc...

ハンドシェイク関数関連の構成を大幅改良。
Web記事を https ( SSL )でGETする関数を追加。
それに伴い、WiFiClientSecure.h をインクルード。
サンプルスケッチの大幅改良。
その他、軽微な修正。

-以下の関数を追加-
EWS_HandShake_main
Get_Http_Req_Status
EWS_https_Web_Get
(この関数はメモリを多く消費するので注意)

以下の関数を追加

EWS_Dev_AutoLIP_HandShake

WebSocket用のHTMLヘッダファイルを分割し、ローカルIPアドレスを自動取得して盛り込めるようにしました。

ESP8266のウォッチドッグタイマを作動させる猶予時間を作るために、所々 yield() を追加しました。
それにより、動作が安定したと思います。
サンプルスケッチも修正しました。

-NEW class-
EWS_BrowserReceiveTextTag2
EWS_Status_Text2
EWS_WebSocket_Reconnection_Button2
EWS_Close_Button2
EWS_Window_ReLoad_Button2

(1.42)
ESP8266DataReceive_SD_write関数を修正しました。

当方のEasyWebSocket beta 1.39 ライブラリをSPI接続のSDカードでできるように更新。SPIFFSは使えません。
SPIFFSよりも速いです。
細かなバグやライブラリ再編、ボタンデザイン変更など。
