only sending first 8 digits of value

[jeti]

Hi all,

I am working on a I Button reader (Key Holder for homestatus use). I have everything working but one detail...
I have 2 seperat OneWire conections (will be 4 in future), each is connected to one reader. Getting the ID of each button works fine but on the first reader I get the ID (8 byte long) and random numbers attached to the end when I send it.
On the second reader there is also a number attached but it stays the same.

• is there a way to shorten the send value (V_VAR1) to valid digits?

thanks in advance

oh yes, this is the sketch I am using:

// Enable debug prints to serial monitor
#define MY_DEBUG 

// Enable and select radio type attached
//#define MY_RADIO_NRF24
#define MY_RADIO_RFM69
#define MY_IS_RFM69HW
#define MY_RFM69_FREQUENCY RF69_433MHZ

#define MY_NODE_ID 102 

#include <SPI.h>
#include <MySensors.h>  
#include <OneWire.h>

// This is the pin with the 1-Wire bus on it
OneWire ds_1(3);
OneWire ds_2(4);
OneWire ds_3(5);
OneWire ds_4(6);




// unique serial number read from the key
byte addr_1[8];
int addr_1_last;
byte addr_2[8];
int addr_2_last;


// poll delay (I think 750ms is a magic number for iButton)
int del = 750;

#define CHILD_ID_1 1
#define CHILD_ID_2 2
#define CHILD_ID_3 3

MyMessage ReadMsg_1(CHILD_ID_1, V_VAR1);
MyMessage ReadMsg_2(CHILD_ID_2, V_VAR2);
MyMessage ReadMsg_3(CHILD_ID_3, V_VAR3);

void setup() {
  Serial.begin(115200);
}

void presentation()  {
  sendSketchInfo("iButton Reader", "1.0");
  present(CHILD_ID_1, S_CUSTOM);
  present(CHILD_ID_2, S_CUSTOM);
  present(CHILD_ID_3, S_CUSTOM);
}

void loop() {
byte result;

  // search looks through all devices on the bus
   ds_1.reset_search();
     for( int i = 0; i < 8;  ++i )
  addr_1[i] = (char)0;
   ds_1.search(addr_1);
//   Serial.println(ds_1.crc8(addr_1,7));
  if(ds_1.crc8(addr_1,7) == 0 && addr_1_last == 0) {

  send(ReadMsg_1.set(0)); 
addr_1_last = 1;

  for( int i = 0; i < 8;  ++i )
  addr_1[i] = (char)0;
  }  
  else if (ds_1.crc8(addr_1,7) >> 0  && addr_1_last == 1){

    send(ReadMsg_1.set(addr_1,HEX)); 
     addr_1_last = 0;

  }
   ds_2.reset_search();
     for( int i = 0; i < 8;  ++i )
  addr_2[i] = (char)0;
   ds_2.search(addr_2);
 //  Serial.println(ds_2.crc8(addr_2,7));
  if(ds_2.crc8(addr_2,7) == 0 && addr_2_last == 0) {

  send(ReadMsg_2.set(0)); 
addr_2_last = 1;

  for( int i = 0; i < 8;  ++i )
  addr_2[i] = (char)0;
  }  
  else if (ds_2.crc8(addr_2,7) >> 0  && addr_2_last == 1){
    

    send(ReadMsg_2.set(addr_2,HEX)); 
     addr_2_last = 0;

  }

  delay(del);
  return;
  }

edit:
for clarification:
this is the 8 byte code:
"0102E47F1600003F"
but V_VARxxx is something like:
"0102E47F1600003F0000017CD2861800"
so first 16 digits are correct then random :-(
