Arduino的问题<-&燃气轮机；Cordova（Android）串行通信

我有一个适用于android的cordova 6应用程序，我想在这里与一个通过USB连接的Arduino进行通信。为此，我使用-Plugin，它使用

不幸的是，我的设置有问题。请求权限是可行的，但当我尝试实际打开串行连接时，我在

adb logcat

：Java.io.IOException:Error queueing request 这意味着在我调用

serial.open

之后，既不会调用成功回调，也不会调用错误回调

我的android设备： -安卓5.1.1 -Allwinner A33芯片组

我的串行设备： -Arduino Uno或Arduino Nano -通过usb连接到Android

我的Javascript代码：

myApp.serial = {
  initialize: function(){
    // Arduino Nano China 1a86:7523
    // Arduino Uno original 2a03:0043
    var serial_device = {vid: '2a03',
      pid: '0043',
      //driver: 'CdcAcmSerialDriver'
      //driver: 'Ch34xSerialDriver'
      //driver: 'Cp21xxSerialDriver'
      //driver: 'FtdiSerialDriver'
      //driver: 'ProlificSerialDriver'      
    };
    serial.requestPermission( serial_device, this.initialize_success, this.initialize_error);
  },
  initialize_success: function(){
    toLog("Serial initialized", 4);
    var opts = { baudRate: 9600 };
    serial.open(opts, this.open_success, this.open_error);
  },
  initialize_error: function(){
    toLog("Error initializing serial!", 1);
  },
  open_success: function(){
    toLog("Serial connectino opened", 4);
    serial.registerReadCallback(this.on_serial_read, this.on_serial_read_error);
  },  
  open_error: function(){
    toLog("Error opening serial connection!", 1);
  }
}  

adb logcat

似乎没有一个司机在工作。不过，logcat消息略有不同

这是否意味着我的android设备不受支持，或者有什么我可以尝试的吗？

Arduino解决方案：

port.dtr = true // for arduino, ...
port.rts = true

爪哇

port.setDTR(true);
port.setRTS(true);
