obnizのページを見ていたら、M5StickC用のobnizOSの説明があったので、試してみました。
勉強がてら、以下のページにある「BLEセントラルコンソール」をM5stickCに移植してみました。
BLEセントラルコンソール
https://obniz.io/ja/webapp/7
BLEセントラルコンソール
ブラウザから、M5StickCのBLEセントラル機能を使って、周辺のBLEデバイスを操作します。
（ESP32の機能を使っているので、M5StickCでなくても動きます）
以下の機能を有しています。
・obniz_idを入力して、obnizに接続します。
・BLEデバイスを探索します。
・BLEデバイスに接続し、PrimaryServiceをDiscoveryします。
・各PrimaryServiceにあるCharacteristicを一覧表示します。
・各Characteristicに対して、Read/Writeします。
こんな感じのWebページです。
obnizにはBLEセントラルのJavascript APIがあるので、そこまで高度な知識がなくても実装できました。
また、オリジナルのBLEセントラルコンソール のソースコードが非常に参考になりました。こちらのコードを8割がた流用させていただいています。
今回再構築したのは、私がVue使いであるためです。
ということで、以下の技術を使っています。
- Vue
- Bootstrap(v3.4.1)
- アロー関数などの最新Javascript
M5StickCへのobnizOSの書き込み
以下に記載の通りにやれば、特に詰まることはありませんでした。
https://obniz.io/ja/doc/obnizos/os_install
ただし、書き込み時に失敗することがあり、ボーレートを落とすことで成功しました。
obniz_cli flashos -b 115200
書き込みが完了し、再起動すると、デバイスキーとお近くのWiFiのSSID/パスワードを入力する必要があります。
上記のためには、Teratermなどのコンソールを接続する必要があります。
ソースコード
以下のソースコードを、どこかにホスティングして、ブラウザからアクセスします。

以下のところでは、M5StickCのクラスを使っています。
// obniz = new Obniz(this.obniz_id);
obniz = new M5StickC(this.obniz_id);
これまでどおり、Obnizを使ってもよいですが、obniz.led.on()/obniz.led.off() を使っています。M5StickCの内蔵LEDを使う場合は、new M5StickCの方を使ってください。
使い方
使い方は簡単です。
「obniz_id」のところに、お手持ちのobnizデバイスのobniz_idを入力して、「Connect」ボタンを押下します。
接続が完了すると、obnizデバイスに書き込んであるファームウェアのバージョンが表示されます。
そうすると、自動的にobnizデバイスの周りにあるBLEデバイスを探索し始めます。
見つかったデバイスは、「Devices」のところに追加されていきます。
Deviceを選択すると、Detailのところに、アドレスやらAdvertiseDataやらScanResponse等々が表示されます。
次に、接続したいBLEデバイスを「Devices」から選択し、Connectボタンを押下します。
そうすると、「Services」のところに、PrimaryServiceの一覧が表示されます。
さらに、「Services」の中のPrimaryServiceを選択すると、それに属するCharacteristicが「Charactersitics」に表示されます。
Characteristicを選択すると、そのCharacteristicにReadし、その値がDetailのところに表示されます。書き込みをしたい場合には、Detailのテキストボックスに16進数文字列で入力して「Write」ボタンを押下します。
補足
以下のページにあるWebアプリが、M5StickCで動かないのは、使っているobniz.jsのバージョンが古いだけなので、単にそこを直せば動くようです。
