CCCD Handle not found

Ok, success! Not that I know why it did not work in the first place, but by getting rid of the cccd-handle altogether, I'm now able to receive data from 6 sensors to Bangle + calculating altitude from the barometer.

31.54c co2:554 IAQ:56 Hum:25 1001.64 pa Gas:34170 Alt:-0.17m

For the benefit of others, here's what I did:

On Bangle side:
Nothing, i.e. no need to handle_cccd = ...,

On Arduino side:

Changed to:

BLEShortCharacteristic temperatureCharacteristic(BLE_SENSE_UUID("2001"), BLERead | BLENotify);

from:

BLEShortCharacteristic temperatureCharacteristic(BLE_SENSE_UUID("2001"), BLERead);

...and put this in the loop function:

void loop(){
  while (BLE.connected()){

    static auto printTime = millis();

    BHY2.update();
    nicla::leds.setColor(blue);

    if (millis() - printTime >= 1000) {

      printTime = millis();

      float temperatureValue = temperature.value();
      temperatureCharacteristic.writeValue(temperatureValue * 100);
      Serial.println(temperatureValue);

      uint32_t co2 = bsec.co2_eq();
      co2Characteristic.writeValue(co2);

      float airQuality = float(bsec.iaq());
      bsecCharacteristic.writeValue(airQuality);

      float pressureValue = pressure.value();
      pressureCharacteristic.writeValue((pressureValue - 800) * 100);
      Serial.println(pressureValue);

      float humidityValue = humidity.value();
      humidityCharacteristic.writeValue(humidityValue);
      
      unsigned int g = gas.value();
      gasCharacteristic.writeValue(g);
    }
