1、wx.closeBLEConnection

2、closeBluetoothAdapter

wx.closeBLEConnection({
    deviceId: self.deviceId,
    success: function (res) {

     console.log(JSON.stringify(res));

    },
    fail: function (res) {
        console.log(JSON.stringify(res));
    }
});

wx.closeBluetoothAdapter({
    success: function (res) {

         console.log(JSON.stringify(res));

    },
    fail: function (res) {
        console.log(JSON.stringify(res));
    }
});

这样先后执行，closeBluetoothAdapter先返回成功，然后closeBLEConnection就总返回失败
