Set up a BLE-Service on the Nano 33 BLE Sence

Hey guys,

I want to run a peripheral BLE-Service on the nano 33 BLE Sence wich contains the temperature values of the integrated sensor, so that a central device can read them or gets notifications. Unfortunatly I constantly get an error as result, while compiling the code. The error message is in the .txt. Here is the code:#

#include <Arduino_HTS221.h>
#include <ArduinoBLE.h>

BLEService Bauteiltemperatur("19b10011-e8f2-537e-4f6c-d104768a1214");

BLEUnsignedCharCharacteristic Sensor1("19b10012-e8f2-537e-4f6c-d104768a1214" , BLERead | BLENotify);

float Temperatur1 = 0;
void setup() {
  float Temperature1 = HTS.readTemperature();
  Serial.begin(9600);
  while(!Serial);

  if(!HTS.begin()) {
    Serial.println("Initialisierung des Temperatursensors fehlgeschlagen");
    while(1);
  }
  if(!BLE.begin()) {
    Serial.println("BLE-Startvorgang fehlgeschlagen");
    while(1);
  }
  pinMode(LED_BUILTIN, OUTPUT);
Bauteiltemperatur.addCharacteristic(Sensor1);
BLE.setLocalName("Messaufbau");
BLE.setAdvertisedService(Bauteiltemperatur);
BLE.addService(Bauteiltemperatur);
Sensor1.writeValue(Temperatur1);

BLE.advertise();
Serial.println("Bluetooth-Gerät aktiv, warte auf Verbindungen...");

}

void loop() {
  BLEDevice central = BLE.central();

  if(central) {
    Serial.print("Verbunden mit PC:");
    Serial.println(central.address());
    digitalWrite(LED_BUILTIN, HIGH);

    while (central.connect());
        updateSensor1 ();
        Serial.print("Temperatur: ");
        Serial.print(Temperature1);
        Serial.print("°C");
        delay(1000);
      }
    
  }
   
void updateSensor1 () {
  float Temperatur1 = HTS.readTemperature ();
  Serial.print("Sensor 1:")
  Serial.println(Temperatur1);
  Serial.print("°C");
  Sensor1.writeValue(HTS.readTemperature());
}

Thank u for the help!

The error message is confusing because Serial is a macro:

#define Serial SerialUSB

The problem is you're missing the semicolon on the end of the line that comes before:

Serial.print("Sensor 1:")
