IOS Serial redpark未向Serial发送数据？

嗨，我对IOS真的很陌生，我正在学习一个示例代码，它可以用RedPark电缆将字符串写入串行。 我有我正在学习的示例代码，它可以工作，并且可以将字符串发送到Arduino Serial。 另外，我有我正在编写的基于示例代码的代码，但现在不起作用。 我已经尝试了几天，在网上搜索了很多，但仍然不明白为什么我的代码不起作用

有人能告诉我为什么我的代码不起作用吗

不同之处在于，示例使用代码实现接口，而我使用脚本。我的代码也会编译和运行，但不会将数据发送到串行端口。

我将尽快发布所需的更多信息。

我终于编写了一个简单的测试应用程序，它可以工作并可以将数据发送到串行电缆： 对于Arduino： 阿杜伊诺

unsigned char inChar;
unsigned char commandChar;
char command[100];
int commandLength = 0;
String currentCommand;
int i=0;   //line 10

int w1In1 = 22;
int w1In2 = 23;
int w1Pwm = 9;
int w2In1 = 25;    //int w2In1 = 7;
int w2In2 = 24;    //int w2In2 = 6;
int w2Pwm = 5;    //line 17

int tempLeng=0;
int tempSpeed=0; //line 20

void setup(){
  currentCommand="";
  pinMode(w1In1, OUTPUT);
  pinMode(w1In2, OUTPUT);
  pinMode(w1Pwm, OUTPUT);
  pinMode(w2In1, OUTPUT);
  pinMode(w2In2, OUTPUT);
  pinMode(w2Pwm, OUTPUT);

  pinMode(13, OUTPUT);
  Serial.begin(9600);
  Serial.println("ready");
} //line 30

void loop(){
  if(Serial.available() > 0){
    readChar();   
    Serial.print(currentCommand);//
  }
}


//*******************Reading psedo commands from Serial buffer*******************
void readChar(){
  commandChar = Serial.read();

//  if(commandChar != '$'&&){
  if( commandChar != '\r' && commandChar!='\n'&&commandChar!='@'){
    if(commandLength < 999){
     command[commandLength++]=commandChar;
   }
 }
 else{

  if(commandLength>0){
    command[commandLength]='\0';
    Serial.print("commandLength:");
    Serial.println(commandLength);
    Serial.print("arduino received >");
    Serial.println(command);
    for(i=0;command[i]!='\0';i++)
    { currentCommand +=command[i];}
    //*********************************Processing

    //***********************************processing
    commandLength = 0;
    memset(command,0b00000000, sizeof(command)); 

   }
  }

}

为应用程序输入代码：

首先，您需要RedPark串行电缆库，可从RedPark网站下载：

因此，当您在文本字段中输入一个字符串并按return键时，该字符串将写入Arduino串行端口，您可以在串行监视器中读取该字符串
