Ryo Iizuka / Mbed 2 deprecated WebSocketSample

MiMicSDK Websocket module sample program.

Dependencies:   NyFileSystems libMiMic mbed-rtos mbed

Fork of UPnPBasicDevice by Ryo Iizuka

This is Websocket server.

WebSocketのサンプルです。 MiMicSDKのWebsocketはhttpdの1モジュールとして動作するので、ファイルサーバ等と一緒に動かすことが出来ます。

ファームウェアを書き込んだ後にブラウザから "http://192.168.128.39/" にアクセスすると、AIN1のデータをリアルタイムに表示するページが開きます。
