hi phi,

 

i have looked a lot closer at the ethernet interface requirements.It is a peer to peer TCP/IP, only half duplex and TCP/IP port is 2111. Wouldn't auto detecting in internet options look after all these parameters?

 

Another thing the command structure for some reason is part string and uint. How do I send this correctly?

sMN Rreqdata    is string and

21 is uint

 

I have tried this and did not work (break up into two lines)

int format b=21

 

myClient.write("sMNRreqdata" ) //on 1st line

myClient.write(b)  //on second line

 

Any ideas for me.

 

I will double check the hardware setting in the scanner again.

 

 

Hi phi,

 

Happy new year 2012.

 

must be little endian. I tried

byte b=21;

 

myClient.write("sMN Rreqdata");  //1st line

myClient.write(b&0xFF);  //2nd line

 

did not work? would this be sending 21 on a different line. How would I send the command sMN Rreqdata 21 on the one line? where "sMN Rreqdata" is a string and 21 is a 2byte uint.

 

Any other suggestions?

 

 

still can't get the scanner to response to continuous measure command....

 

I have even gone to the extent of creating btye[]  format which is the actual command in bytes. the command is  "sMNmLRreqdata" and 0021hex 2byte uint

 

See my code below:-  Any suggestions? Is there a library I am missing?

import processing.net.*;
Server myServer; //is the scanner

  // Request continuous measured data from scanner
  myClient.clear();
  delay(20);
  myClient.write(format);  // note: the command is  "sMNmLRreqdata" is a string and 0021hex  2byte uint
  //myClient.write("sMNmLRreqdata"); 
  //delay(20);
  //myClient.write(a);  //a=0 dec
  //myClient.write(b);  //b=33 dec
  println(format); 
}

  while (myClient.available()<0)
{
    rawdata1 = myClient.read();
    rawdata2 = myClient.read();

    println(rawdata1);
