DW1000 + ESP32 - no ranging

Ultra-Wideband
1

Hello,
I started work with DW1000.
I connected it to ESP32 (Healtec with Lora).
I’ve uploaded to ESP32 for tag:

#include <SPI.h>
#include "DW1000Ranging.h"

#define SPI_SCK 18
#define SPI_MISO 19
#define SPI_MOSI 23
#define DW_CS 4

// connection pins
const uint8_t PIN_RST = 27; // reset pin
const uint8_t PIN_IRQ = 34; // irq pin
const uint8_t PIN_SS = 5;   // spi select pin

void setup()
{
    Serial.begin(115200);
    delay(1000);
    //init the configuration
    SPI.begin(SPI_SCK, SPI_MISO, SPI_MOSI);
    DW1000Ranging.initCommunication(PIN_RST, PIN_SS, PIN_IRQ); //Reset, CS, IRQ pin
    //define the sketch as anchor. It will be great to dynamically change the type of module
    DW1000Ranging.attachNewRange(newRange);
    DW1000Ranging.attachNewDevice(newDevice);
    DW1000Ranging.attachInactiveDevice(inactiveDevice);
    //Enable the filter to smooth the distance
    //DW1000Ranging.useRangeFilter(true);

    //we start the module as a tag
    DW1000Ranging.startAsTag("7D:00:22:EA:82:60:3B:9C", DW1000.MODE_LONGDATA_RANGE_LOWPOWER);
}

void loop()
{
    DW1000Ranging.loop();
}

void newRange()
{
    Serial.print("from: ");
    Serial.print(DW1000Ranging.getDistantDevice()->getShortAddress(), HEX);
    Serial.print("\t Range: ");
    Serial.print(DW1000Ranging.getDistantDevice()->getRange());
    Serial.print(" m");
    Serial.print("\t RX power: ");
    Serial.print(DW1000Ranging.getDistantDevice()->getRXPower());
    Serial.println(" dBm");
}

void newDevice(DW1000Device *device)
{
    Serial.print("ranging init; 1 device added ! -> ");
    Serial.print(" short:");
    Serial.println(device->getShortAddress(), HEX);
}

void inactiveDevice(DW1000Device *device)
{
    Serial.print("delete inactive device: ");
    Serial.println(device->getShortAddress(), HEX);
}

and second unit for anchor:

#include <SPI.h>
#include "DW1000Ranging.h"

#define ANCHOR_ADD "83:17:5B:D5:A9:9A:E2:9C"

#define SPI_SCK 18
#define SPI_MISO 19
#define SPI_MOSI 23
#define DW_CS 4

// connection pins
const uint8_t PIN_RST = 27; // reset pin
const uint8_t PIN_IRQ = 34; // irq pin
const uint8_t PIN_SS = 4;   // spi select pin

void setup() {
  Serial.begin(115200);
  delay(1000);
  //init the configuration
  DW1000Ranging.initCommunication(PIN_RST, PIN_SS, PIN_IRQ); //Reset, CS, IRQ pin
  //define the sketch as anchor. It will be great to dynamically change the type of module
  DW1000Ranging.attachNewRange(newRange);
  DW1000Ranging.attachBlinkDevice(newBlink);
  DW1000Ranging.attachInactiveDevice(inactiveDevice);
  //Enable the filter to smooth the distance
  //DW1000Ranging.useRangeFilter(true);
  
  //we start the module as an anchor
  DW1000Ranging.startAsAnchor("82:17:5B:D5:A9:9A:E2:9C", DW1000.MODE_LONGDATA_RANGE_ACCURACY);
}

void loop() {
  DW1000Ranging.loop();
}

void newRange() {
  Serial.print("from: "); Serial.print(DW1000Ranging.getDistantDevice()->getShortAddress(), HEX);
  Serial.print("\t Range: "); Serial.print(DW1000Ranging.getDistantDevice()->getRange()); Serial.print(" m");
  Serial.print("\t RX power: "); Serial.print(DW1000Ranging.getDistantDevice()->getRXPower()); Serial.println(" dBm");
}

void newBlink(DW1000Device* device) {
  Serial.print("blink; 1 device added ! -> ");
  Serial.print(" short:");
  Serial.println(device->getShortAddress(), HEX);
}

void inactiveDevice(DW1000Device* device) {
  Serial.print("delete inactive device: ");
  Serial.println(device->getShortAddress(), HEX);
}

And in serial monitor I see only ID + named TAG or Anchor. How to reach distance between tag and anchor? Connections are direct between DW1000 and ESP32

hello, do you solve the problem?

I have the same problem, I do not have any message in serial.
