RF24Network network.failures() printing zero

[jojokekoa]

Hello,

I am using the RF24 radio modules and the RF24Network library to communicate between an Arduino uno and a series of Arduino nanos. I was trying to implement the network.failures() function to print out the number of successfully sent payloads but all I get is zero. What am I doing wrong?

Here is the snippet of relevant code from my base module (the uno)

void loop(void) {

  network.update();  // Check the network regularly
  while (network.available()) {  // Is there anything ready for us?
 
    RF24NetworkHeader header;  // If so, grab it and print it out
    payload_t payload;
    network.read(header, &payload, sizeof(payload));
    
    // print the payload for each node
    printPayload(payload);

    uint32_t fails, success;
    network.failures(&fails, &success); // Return the number of failures and successes for all transmitted payloads, routed or sent directly 
    Serial.print(F(", Success="));
    Serial.print(success);
    Serial.print(F(", Failures="));
    Serial.println(fails);
  }
}

this is some of my output

Node ID: 1, Received packet: counter=1664, origin timestamp=3330000, moisture=59.37, Percentage=0.00, Success=0, Failures=0
Node ID: 1, Received packet: counter=1665, origin timestamp=3332000, moisture=59.37, Percentage=0.00, Success=0, Failures=0
Node ID: 1, Received packet: counter=1666, origin timestamp=3334000, moisture=59.36, Percentage=0.00, Success=0, Failures=0
Node ID: 1, Received packet: counter=1667, origin timestamp=3336000, moisture=59.38, Percentage=0.00, Success=0, Failures=0

It doesn't look like that code could produce that output.

I think the function should be used on the sending side,
how could the receiver know of failures?

[jojokekoa]

Ive also tried on the sending side and I get similar output.

heres the code for the sender(the arduino nano)

void loop() {

  uint32_t fails, success;

  network.update();  // Check the network regularly

  unsigned long now = millis();

  // If it's time to send a message, send it!
  if (now - last_sent >= interval) {
    last_sent = now;

    Serial.print(F("Sending... "));
    payload_t payload = { this_node, millis(), packets_sent++, updateMoisture() };  // payload consists of {ID, ms, packets, moisure}
    RF24NetworkHeader header(/*to node*/ other_node);
    bool ok = network.write(header, &payload, sizeof(payload));
    Serial.println(ok ? F("ok.") : F("failed."));

    network.failures(&fails, &success); // Return the number of failures and successes for all transmitted payloads, routed or sent directly 
    Serial.print(F(", Success="));
    Serial.print(success);
    Serial.print(F(", Failures="));
    Serial.println(fails);
  }
}

My bad I cut out the part of the code that formats that output. printPayload is a function that I wrote.

void printPayload(payload_t p) {
  Serial.print(F("Node ID: "));
  Serial.print(p.nodeID, OCT);
  Serial.print(F(", Received packet: counter="));
  Serial.print(p.counter);
  Serial.print(F(", origin timestamp="));
  Serial.print(p.ms);
  Serial.print(F(", moisture="));
  Serial.print(p.moistValue);
  Serial.print(F(", Percentage="));
  Serial.print(calculateMoisturePercentage(p.moistValue));
}

It prints out the contents of the payload that is sent from each nano and is working as expected.

You have enabled the feature via the define mentioned in the documentation?

[jojokekoa]

yes, ive gone into the header file and uncommented #define ENABLE_NETWORK_STATS

[Whandall]

Then it should work.

I never used that layer, so I can only guess.

[jojokekoa]

Maybe the mistake is elsewhere then. Thanks for the help!
