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
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。
