I have an arduino that has connected one NRF24L01 + module and a motion sensor and other arduino that has just connected a NRF24L01 module configured as the father of the first . The gateway receives packets of motion sensor but does not return the ack

This is the source code or gateway

MyTransportNRF24 transport(7, 8,RF24_PA_HIGH);
MySigningNone signer;
MyHwATMega328 hw;
MySensor gw(transport,hw);

bool begin_transmission=false;
int who_am_i=-1;
int which_sensor=-1;

String send_telegram="";
unsigned long timeout=10000;

MyMessage msg(MOTION_SENSOR_ID,V_VAR1);


void response(const MyMessage &m){
    
  String message_text=m.getString();
  Serial.println(message_text);
  if(message_text==BEGIN_TRANSMISSION && !begin_transmission){
    begin_transmission=true;
    begin_transmission_time=millis();
  }
  if(begin_transmission){
    if(who_am_i<0 && message_text.startsWith(WHO_AM_I)){
      who_am_i=message_text.substring(String(WHO_AM_I).length()+1).toInt();
    } 
    else if(which_sensor<0 && message_text.startsWith(WHICH_SENSOR)){
      which_sensor=message_text.substring(String(WHICH_SENSOR).length()+1).toInt();
    }
    else if(whath<0 && message_text.startsWith(WHATH)){
      whath=message_text.substring(String(WHATH).length()+1).toInt();
    }
    else if(message_text.startsWith(SEND_TELEGRAM)){
      send_telegram+=message_text.substring(String(SEND_TELEGRAM).length()+1);
    }
    else if(message_text.startsWith(END_TRANSMISSION)){
      begin_transmission=false;
      if(send_telegram!=""){
        String telegram=String("Node ")+who_am_i+String(" Sensor ")+which_sensor+String(" Valor ")+whath+String(" ")+send_telegram+String("*");
        who_am_i=-1;
        which_sensor=-1;
        whath=-1;
        send_telegram="";
        Serial.println(telegram);
      }
     }
    }
  msg.setDestination(MOTION_SENSOR_NODE);
  gw.send(msg.set(OK),true);
}
 
void setup() 
{ 
  Serial.begin(115200);
  gw.begin(response,NODE_ID,false,NULL);
  
}
 
void loop()
{
     gw.process();
     gw.wait(10000); // Wait 10 seconds
     if((begin_transmission_time+timeout)<millis()){
      begin_transmission=false;
      who_am_i=-1;
      which_sensor=-1;
      whath=-1;
      send_telegram="";

}

Serial port output for gateway is

And serial port output for motion sensor sketch is

Where is the problem? It seems that the gateway can not find the motion sensor.
Moreover, there is a method in the myMessage class to know id of node sending a message?

Thanks

@SiLeX So it may be due to an incorrect connection? Pins of module are untagged and I connected them according to the positions of schemes that I found online. All modules have same pinout?

@BartE Its simply a test. My final project is to connect a motion sensor and a NRF24L01+ module to an arduino nano board. And in the other side another arduino with a NRF24L01+ module connected to a Raspberry.
But at this moment I just want to test communication between two nodes

I have a NRF24L01+ module connected to an arduino uno board. I use a 100uF 25V capacitor. When execute sketch arduino hangs and returns this text in serial output:

send: 2-2-0-0 s=255,c=3,t=15,pt=2,l=2,sg=0,st=ok:0

I tried to call MySensor constructor and begin function with and without parameters.

Where is the problem?

Thanks

The code I used is

#include <MySensor.h>
#include <MySigningNone.h>
#include <MyTransportNRF24.h>
#include <MyHwATMega328.h>
#include <SPI.h>
 
#define ID 0
#define OPEN 1
#define CLOSE 0

MyTransportNRF24 transport(9, 10);
MySigningNone signer;
MyHwATMega328 hw;
MySensor gw(transport,hw);
//MySensor gw;
MyMessage msg(ID, V_TRIPPED);

void response(const MyMessage &m){

}
 
void setup() 
{ 
  Serial.begin(115200);
  //Serial.print("Setup ");
  gw.begin(response,2,false,AUTO);
  //gw.begin();
  Serial.println("begin");
  gw.present(ID, S_DOOR,"Sensor de prova",false); 
}
 
void loop()
{
     Serial.print("Identificador ");
     Serial.println(gw.getNodeId());
     gw.send(msg.set(OPEN));
     gw.sendSketchInfo("Sketch de prova","0.0", true);
     delay(1000); // Wait 10 seconds
}```
