Android BLE 切断コールバックが呼ばれない

Posted at
切断処理
//切断したい時
gatt.disconnect();
gatt.close();

と一気にやってしまうと切断コールバックが呼ばれなくなる場合があるみたい。
以下のようにしたら解決したように見える

切断処理
//切断したい時
gatt.disconnect();

//BluetoothGattCallback
public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
    if (newState == BluetoothProfile.STATE_DISCONNECTED) {
        gatt.close();    //disconnect()の結果のコールバック来てからclose
    }
}

disconnect=切断 を確認してからclose=閉じる のは当然といえば当然かもしれない・・・

//AndroidBLEのコールバック地獄めちゃくちゃキツくないですか
