Re: [xSocket-develop] nbc and reading incomming frames with bytes

[<jun...@wp...>]

Hi Gregor,<br>
<br>
I get strange output. <br>
<br>
If I expect&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; F0 C1 01 01 01 81 00&nbsp;&nbsp;&nbsp;&nbsp; I get&nbsp;&nbsp;&nbsp;&nbsp; 1007d 1007d 81 81 81 1007d 0 <br>
If I expect&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; F0 C1 01 01 01 81 01&nbsp;&nbsp;&nbsp;&nbsp; I get&nbsp;&nbsp;&nbsp;&nbsp; 1007d 1007d 81 81 81 1007d 81<br>
<br>
Do You know maybe what could be a reason ? It is correct that there is
7 bytes and the last one changes but where does those funny values came
from? I tried readStringByLength(available)&nbsp; and I get same wrong
output. Maybe function stringToHex doesn't work properly? Is it
possible to get Hex values from ByteBuffer[] directly?
DataConverter.toHexString(data) won't work.<br>
<br>
I wrote<br>
<br>
if (available &gt; 0) {<br>
&nbsp;&nbsp; ByteBuffer[] data = nbc.readByteBufferByLength(available);<br>
&nbsp;&nbsp; String s = DataConverter.toString(data);<br>
&nbsp;&nbsp; System.out.println(stringToHex(s));<br>
return true;<br>
<br>
//and I use this function to convert to Hex<br>
<br>
public static String stringToHex(String base)<br>
&nbsp;&nbsp;&nbsp; {<br>
&nbsp;&nbsp;&nbsp;&nbsp; StringBuffer buffer = new StringBuffer();<br>
&nbsp;&nbsp;&nbsp;&nbsp; int intValue;<br>
&nbsp;&nbsp;&nbsp;&nbsp; for(int x = 0; x &lt; base.length(); x++)<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int cursor = 0;<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; intValue = base.charAt(x);<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; String binaryChar = new String(Integer.toBinaryString(base.charAt(x)));<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for(int i = 0; i &lt; binaryChar.length(); i++)<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if(binaryChar.charAt(i) == '1')<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; cursor += 1;<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if((cursor % 2) &gt; 0)<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; intValue += 128;<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; buffer.append(Integer.toHexString(intValue) + " ");<br>
&nbsp;&nbsp;&nbsp;&nbsp; }<br>
&nbsp;&nbsp;&nbsp;&nbsp; return buffer.toString();<br>
}<br>
