nRF24L01 receive from 2 transmitters?

i have few arduino boards nrf24l01 transceivers on them. have 2 boards sending sensor values , 1 receive them , putting in plx-daq spreadasheet. able either 1 work @ time, have not been able both send data , other 1 pick them both @ same time.

this have 1 of sending (i used library tmrh20)

code: [select]

#include <spi.h> 
#include "rf24.h"

rf24 myradio (7, 8);
byte addresses[][6] = {"0"};

struct package
{
  int id=1;
  float moisture;
};


typedef struct package package;
package data;


void setup()
{
  serial.begin(9600);
  delay(1000);
  myradio.begin(); 
  myradio.setchannel(115);
  myradio.setpalevel(rf24_pa_max);
  myradio.setdatarate( rf24_250kbps ) ;
  myradio.openwritingpipe( addresses[0]);
  delay(1000);
}

void loop()
{
  myradio.write(&data, sizeof(data));

  serial.println(analogread(a0));
  data.moisture = analogread(a0);
  delay(1000);

}

and respective receive:

code: [select]

#include <spi.h> 
#include "rf24.h"

rf24 myradio (7, 8);
struct package
{
  int id=0;
  float moisture;
};

byte addresses[][6] = {"0"};



typedef struct package package;
package data;
int row = 0;
int x = 0;
void setup()
{
  serial.begin(9600);
  delay(1000);
  serial.println("cleardata");
  serial.println("label,time,moisture");
  serial.println("resettimer");
  myradio.begin();
  myradio.setchannel(115);
  myradio.setpalevel(rf24_pa_max);
  myradio.setdatarate( rf24_250kbps ) ;
  myradio.openreadingpipe(1, addresses[0]);
  myradio.startlistening();
}


void loop() 
{

  if ( myradio.available())
  {
    while (myradio.available())
    {
      myradio.read( &data, sizeof(data) );
    }
     serial.print("data,time,");
  serial.println((-10.32 * (log(data.moisture) / log(2.718)) + 72.66));
  row++;
  x++;
  if (row > 60)
  {serial.println("cleardata");
  serial.println("row,set,2"); 
  row = 0;}
  }

}

then other send

code: [select]

#include <spi.h> 
#include "rf24.h"

rf24 myradio (7, 8);
byte addresses[][6] = {"0"};

struct package2
{
  int id=1;
  float psi;
};


typedef struct package2 package2;
package2 datas;


void setup()
{
  serial.begin(9600);
  delay(1000);
  myradio.begin(); 
  myradio.setchannel(115);
  myradio.setpalevel(rf24_pa_max);
  myradio.setdatarate( rf24_250kbps ) ;
  myradio.openwritingpipe( addresses[0]);
  delay(1000);
}

void loop()
{
  myradio.write(&datas, sizeof(datas));

  serial.println(analogread(a0));
  datas.psi = analogread(a0);
  delay(1000);

}

and receive that

code: [select]

#include <spi.h> 
#include "rf24.h"

rf24 myradio (7, 8);
struct package2
{
  int id=0;
  float psi;
};

byte addresses[][6] = {"0"};



typedef struct package2 package2;
package2 datas;
int row = 0;
int x = 0;
void setup()
{
  serial.begin(9600);
  delay(1000);
  serial.println("cleardata");
  serial.println("label,time,moisture");
  serial.println("resettimer");
  myradio.begin();
  myradio.setchannel(115);
  myradio.setpalevel(rf24_pa_max);
  myradio.setdatarate( rf24_250kbps ) ;
  myradio.openreadingpipe(1, addresses[0]);
  myradio.startlistening();
}


void loop() 
{

  if ( myradio.available())
  {
    while (myradio.available())
    {
      myradio.read( &datas, sizeof(datas) );
    }
     serial.print("data,time,");
  serial.println(0.29325513196*datas.psi);
  row++;
  x++;
  if (row > 60)
  {serial.println("cleardata");
  serial.println("row,set,2"); 
  row = 0;}
  }

}

this works fine, having trouble getting both of them. guess start off with, possible in first place? tried this:

code: [select]

#include <spi.h> 
#include "rf24.h"

rf24 myradio (7, 8);
struct package
{
  int id=0;
  float moisture;
};



struct package2
{
  int id=0;
  float psi;
};
byte addresses[][6] = {"0"};
typedef struct package package;
package data;
int row = 0;
int x = 0;
typedef struct package2 package2;
package2 datas;
void setup()
{
  serial.begin(9600);
  delay(1000);
  serial.println("cleardata");
  serial.println("label,time,moisture,air pressure");
  serial.println("resettimer");
  myradio.begin();
  myradio.setchannel(115);
  myradio.setpalevel(rf24_pa_max);
  myradio.setdatarate( rf24_250kbps ) ;
  myradio.openreadingpipe(1, addresses[0]);
   myradio.setchannel(95);
  myradio.setpalevel(rf24_pa_max);
  myradio.setdatarate( rf24_250kbps ) ;
  myradio.openreadingpipe(1, addresses[0]);
  myradio.startlistening();
}


void loop() 
{

  if ( myradio.available())
  {
    while (myradio.available())
    {
  myradio.setchannel(115);
      myradio.read( &data, sizeof(data) );
   
     serial.print("data,time,");
  serial.print((-10.32 * (log(data.moisture) / log(2.718)) + 72.66));
  serial.print(",");
 
  myradio.setchannel(95);
  myradio.read( &datas, sizeof(datas) );
  serial.println(0.29325513196*datas.psi);
  row++;
  x++;}
  if (row > 60)
  {serial.println("cleardata");
  serial.println("row,set,2"); 
  row = 0;}
  }

}
obviously, changed channel on second sender match. did because figured interfere each other if sending on same channel. anyway, don't 100% how work, appreciated.

it's been while since did useful nfr2400's, aren't supposed set 'sender' id somewhere?
