    • Sending sensor data from arduino pro mini via NRF24L01+ to raspberry pi 4

      Hello,
      for a project I need to send sensor data to a gateway.

      For this I followed the following tutorial:
      https://www.mysensors.org/build/connect_radio
      https://www.mysensors.org/build/temp
      https://www.mysensors.org/build/raspberry

      The output of my Arduino looks like this:

      16 MCO:BGN:INIT NODE,CP=RNNNA---,FQ=8,REL=255,VER=2.3.2
      28 MCO:BGN:BFR

      The Raspberry has the following output (in debug mode):

      Can someone maybe tell me where my error is and how I can read the sensor data?

      @haloway13
      Hey, as I said below, I have found a solution to the problem.

      I have made use of two other tutorials.
      (Attention German language!)
      https://draeger-it.blog/arduino-lektion-48-temperatursensor-ds18b20/
      https://tutorials-raspberrypi.de/funkkommunikation-zwischen-raspberry-pis-und-arduinos-2-4-ghz/

      If you look at the wiring, I can send you my code so far:

      #include <SPI.h>
      #include "printf.h"
      #include "RF24.h"
      #include <OneWire.h>
      #include <DallasTemperature.h>
      
      #define ONE_WIRE_BUS 2  //Sensor DS18B20 at digital pin 2
      
      RF24 radio(7, 8); // using pin 7 for the CE pin, and pin 8 for the CSN pin
      OneWire oneWire(ONE_WIRE_BUS);
      
      DallasTemperature sensors(&oneWire); // Transfer of the OnewWire reference to communicate with the sensor.
      
      uint8_t address[][6] = {"1Node", "2Node"}; // Let these addresses be used for the pair
      bool radioNumber = 1; //to use different addresses on a pair of radios, we need a variable to uniquely identify which address this radio will use to transmit
      int sensorCount;
      
      float payload = 0.0; 
      int ID = 0; 
      float temperature = 0.0;
      float battery = 0.0;
      
      void setup() {
        Serial.begin(115200);
        while (!Serial) {
          // some boards need to wait to ensure access to serial over USB
        }
        
        // initialize the transceiver on the SPI bus
        if (!radio.begin()) {
          Serial.println(F("radio hardware is not responding!!"));
          while (1) {} // hold in infinite loop
        }
      
        // Set the PA Level low to try preventing power supply related problems
        // because these examples are likely run with nodes in close proximity to
        // each other.
        radio.setPALevel(RF24_PA_LOW);  // RF24_PA_MAX is default.
      
        sensors.begin(); // Start communication with the sensor
        sensorCount = sensors.getDS18Count(); // Reading the number of connected
      
        // save on transmission time by setting the radio to only transmit the
        // number of bytes we need to transmit a float
        radio.setPayloadSize(sizeof(payload)); // float datatype occupies 4 bytes
      
        // set the TX address of the RX node into the TX pipe
        radio.openWritingPipe(address[radioNumber]);     // always uses pipe 0
      
        // set the RX address of the TX node into a RX pipe
        radio.openReadingPipe(1, address[!radioNumber]); // using pipe 1
        
        radio.stopListening();  // put radio in TX mode
      
      } // setup
      
      void loop() {
      
        if(sensorCount ==0){
           Serial.println("No temperature sensors found");
           Serial.println("Please check your circuit!");
         }
        
        sensors.requestTemperatures();
        
          // This device is a TX node
          payload = sensors.getTempCByIndex(0);
          
          unsigned long start_timer = micros();                    // start the timer
          bool report = radio.write(&payload, sizeof(float));      // transmit & save the report
          unsigned long end_timer = micros();                      // end the timer
      
          if (report) {
            Serial.print(F("Transmission successful! "));          // payload was delivered
            Serial.print(F("Time to transmit = "));
            Serial.print(end_timer - start_timer);                 // print the timer result
            Serial.print(F(" us. Sent: "));
            Serial.println(payload);                               // print payload sent
          } else {
            Serial.println(F("Transmission failed or timed out")); // payload was not delivered
          }
      
          // to make this example readable in the serial monitor
          delay(1000);  // slow transmissions down by 1 second
      
      } // loop

    • RE: Sending sensor data from arduino pro mini via NRF24L01+ to raspberry pi 4

      @evb
      Hey, thanks for the quick reply.
      I have checked the wiring several times for correctness.
      Also the config was set up according to the instructions.

      Meanwhile I have found an alternative solution.
      Thanks a lot for your help!
