There is a string variable

public static String MSG;

Its task is to receive a data packet from the X-Bee network and display applications and write to text.

 MSG = new String(xBeePacket.toString()); helloWorld2.appendText("IN: "+MSG+"\n"); //запись в текстовое поле helloWorld2 try (FileWriter writer = new FileWriter(filename(), true)) { writer.append(MSG); writer.append("\r\n"); writer.flush(); } catch (IOException ex) { System.out.println(ex.getMessage()); }

Everything comes to the text field clearly. For example, there are 2 packages: 7E0023910013A200414F926F68FEE8E80011C1050101FCA0550153158E07134650019047505306 7E0023910013A200415B69C75C5AE8E80011C1050101FCA055015158E0715515515515515515515005A1055A5155A5155A07555A5308A105A105A105A104AF426F68FEE8E80011C1050101FCA0550153158E07134650019047505306

But in the file it looks different: 7E0023910013A200414F926F68FEE8E80011C1050101FCA0550153158E07134650019047505306 US FP GPS

You may notice that at the end there are GPS symbols, however, in the package, the codes for these symbols are not recent, it turns out that he also cut part of the package. The strangest thing is that these packages are of the same type and almost identical, but why in one of the packages the program decided to translate characters, and the probability of such a bebird is unpredictable, it may not be at all, and almost all the lines may be filled in this way, while everything in the text field correctly displayed.

  • most likely you have different encodings (the program displays in one encoding, and writes to a file to another). I recommend to know the encoding of incoming messages. Convert them when getting into UTF8, and work already with UTF8 both in the program and in the file. - Alexander Savostyanov
  • Messages most likely go to ASCII, but aren't they compatible? And can it be that a trap with coding arises as if randomly and rarely? - Klaus
  • Converted, nothing has changed - Klaus
  • Randomly, hardly. Show the code in which to convert. - Alexander Savostyanov
  • MSG = new String(xBeePacket.toString().getBytes(), "UTF-8"); - first attempt String MSG = new String(Controller.MSG.getBytes(),"UTF-8"); - second try - Klaus
