[英]Send a Java Map<Integer,String> With XBee
I would send a Java Map with XBee, but I see in the Git repository how they send byte[]. 我将使用XBee发送Java Map,但是我在Git存储库中看到了它们如何发送byte []。 How can I send my Map?
如何发送地图? I thinked use Python for that, but I prefer use Java for all and not use Java for all unless for send the message.
我以为使用Python,但是我更喜欢全部使用Java,除非发送消息,否则不要全部使用Java。
This is my code: 这是我的代码:
public class Comunicacion {
/* Constants */
private static final String PORT = "ttyUSB0";
private static final int BAUD_RATE = 9600;
private static Map<Integer, String> dataToSend = new HashMap<Integer, String>();
public static void main(String[] args) {
XBeeDevice myDevice = new XBeeDevice(PORT, BAUD_RATE);
byte[] dataInByte = dataToSend.getBytes();
try {
myDevice.open();
System.out.format("Sending broadcast data: '%s'", new String(dataInByte));
myDevice.sendBroadcastData(dataInByte);
System.out.println(" >> Success");
} catch (XBeeException e) {
System.out.println(" >> Error");
e.printStackTrace();
System.exit(1);
} finally {
myDevice.close();
}
}
Just an example of a conversion for just about anything to a binary string... However I am unsure of what your sending this info too and the required headers. 只是将任何内容转换为二进制字符串的示例...但是,我不确定您也发送此信息以及所需的标头。 None the less, this may get you what you want, a converted binary value.
但是,这可能会为您带来所需的转换后的二进制值。
public class JavaApplication10 {
static HashMap<String, Boolean> map = new HashMap<>();
public static void main(String[] args){
byte[] dataInByte = map.toString().getBytes();
String sender ="";
for (byte b : dataInByte) {
sender = sender + (Integer.toBinaryString(b));
}
System.out.println(sender);
}
}
