Failed to initialize IMU!

[phayt]

I have already searched the forum for this topic but found no solution. I have just installed the IDE and can run successfully the blink example. There are no errors compiling the example SimpleAccelerometer (relevant snippet below) but running I receive the following message:

Started
Failed to initialize IMU!

My HW is a Nano 33 BLE Sense, Rev 2. There is no external wiring, just the USB. I have loaded the latest mBed: Arduino Mbed OS Nano Boards 4.0.2

The forums suggested added a library (marked in snippet) and using Mbed 1.3.1

The added library did not change behavior and Mbed 1.3.1 is not longer available.

Any help is appreciated!

---------------------- Code snippet ------------------------------------

#include "PluggableUSBHID.h"// Library that needs to be added
#include <Arduino_LSM9DS1.h>

void setup() {
  Serial.begin(9600);
  while (!Serial);
  Serial.println("Started");

  if (!IMU.begin()) {
    Serial.println("Failed to initialize IMU!");
    while (1);
  }

  Serial.print("Accelerometer sample rate = ");
  Serial.print(IMU.accelerationSampleRate());
  Serial.println(" Hz");
  Serial.println();
  Serial.println("Acceleration in g's");
  Serial.println("X\tY\tZ");
}

SOLVED
The required library is
#include "Arduino_BMI270_BMM150.h"
which can be downloaded with the library manager (search on the same name). The library manager also has examples which are accessed through the ... button

------------- Code now looks like -----------------

/* removed as not required
#include "PluggableUSBHID.h"// Library that needs to be added
#include <Arduino_LSM9DS1.h>
*/

#include "Arduino_BMI270_BMM150.h"

const float accelerationThreshold = 2.5; // threshold of significant in G's
const int numSamples = 119;

int samplesRead = numSamples;

void setup() {
  Serial.begin(9600);
  while (!Serial);

  if (!IMU.begin()) {
    Serial.println("Failed to initialize IMU!");
    while (1);
  }

  // print the header
  Serial.println("aX,aY,aZ,gX,gY,gZ");
}
