Gleichzeitige Nutzung Drucksensor und Temperatursensor bei Nano 33 BLE rev2

In der Doku stand "initialize sensor"

der untenstehende Code prüft nur ob die Sensoren arbeiten

  // Check if pressure sensor is started
  if (!BARO.begin()) {
    Serial.println("Failed to initialize pressure sensor!");
    while (1);
  }

  // Check if Temperature and Humidity sensor is started
  if (!HS300x.begin()) {
    Serial.println("Failed to initialize humidity temperature sensor!");
    while (1);
  }

Also kann man auch mehrere Sensoren auslesen, nur einfach die notwendigen Bibliotheken einbinden dann läuft das hier der gesamte Code:
Und das geht ganz einfach nacheinander
Ich dachte ich muß die Sensoren starten zum auslesen
Hier der komplette Code

/*
  LPS22HB - Read Pressure
  HS300x. - Read Temperature and Humidity

  This example reads data from the on-board LPS22HB sensor of the Nano 33 BLE Sense Rev2, 
  converts the atmospheric pressure sensor values to pressure at sea level, and
  temperature and humidity from HS300x sensor and prints them to the 
  Serial Monitor every  5 second.

  The circuit:
  - Arduino Nano 33 BLE Sense Rev2

  This example code is in the public domain.
