Bizan Nishimura / Mbed 2 deprecated MiniSteer2

AndroidのBLEラジコンプロポアプリ「BLEPropo」と接続し、RCサーボとDCモータを制御するプログラムです。 mbed HRM1017で動作を確認しています。 BLEPropo → https://github.com/lipoyang/BLEPropo

Dependencies:   BLE_API mbed

Fork of BLE_RCBController2 by Junichi Katsu

BLEを使ったAndroid用ラジコンプロポアプリ「BLEPropo」に対応するmbed HRM1017用ファームウェアです。
BLEPropoは、GitHubにて公開中。
