Hi gang,
I'm going crazy, I can't run my serial gateway on Arduino UNO R3 with a Distance Sensor maked with Arduino Pro Mini.
Please, can you send me your skecth for both node?
Thank you very much in any case.

Did you add an attachment? Can't see anything. I tried various combinations, if I add DI00 to D4, I cannot seem to flash it, getting errors while uploading. Whatever combination I used on D2 also didn't work. The RFM69 settings can be set for the mysensors lib with MY_RF69_IRQ, etc Did you also connect RST?

@pw44 and so, my first assbled gateway looks like: Now i will try a more robust version, with external antenna.

@erangaj - good! I hope you find the cause of this - let me know if I can do anything else.

I fixed the issue by using the ESP8266 2.7.4 board software and installing https://github.com/espressif/esptool/archive/v3.0.zip and https://github.com/pyserial/pyserial/archive/v3.4.zip and replacing the esptool and pyserial folders in ~/Library/Arduino15/packages/esp8266/hardware/esp8266/2.7.4/tools/ If anybody has a fix for 3.0.2, it would be very much welcome!

@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

btw. This sleep time, is independent of the oscillator used to run the MCU (8Mhz / 1Mhz). As the watchdog has it's own oscillator.
