Yasushi TAUCHI / Mbed 2 deprecated BLE_HVC

オムロンのOKAO Vision HVC-C1BとBLE通信します。

Dependencies:   BLE_API mbed nRF51822

Fork of BLE_ButtonSense by Bluetooth Low Energy

オムロン　OKAO　Vision(ヒューマンビジョンコンポ）HVC-C1BとRedBearLab nRF51822 mbedでBLE通信を行うサンプルです。

HVC-C1Bは、人、手、顔、性別、年齢、表情、顔の向き、視線、目の閉じを推定し、値を返してくれます。 http://plus-sensing.omron.co.jp/egg-project/

main.cppの最初の定義の部分（IDや欲しい項目）を変更すると使えます。 欲しい項目を1に要らない項目は０にしてください。

タイムアウトの処理が入っていませんが、もし入れたい場合は、LEDのHartBeatの処理に追加すれば簡単に出来ると思います。

下記のような感じでメッセージが帰ってきます。
