Iot: BME680 Reading not working properly (programmer mistake, it's working)

[dnutiu]

Describe the bug

I tried to experiment with the BME680 device binding but unfortunately the data which is read is not accurate.

Steps to reproduce

Code:

        internal async Task TakeMeasurement()
        {
            if (_sensorState != SensorState.Initialized)
            {
                _logger.LogWarning($"{DateTimeOffset.Now}:BME680: Attempting to take measurement while sensor is not initialized!");
                _measurement.SetMeasurement(Temperature.FromCelsius(-1), -1, -1);
                return;
            }

            /* Force the sensor to take a measurement. */
            _bme680.SetPowerMode(Bme680PowerMode.Forced);

            var temperature = await _bme680.ReadTemperatureAsync();
            var pressure = await _bme680.ReadPressureAsync();
            var humidity = await _bme680.ReadHumidityAsync();
            _measurement.SetMeasurement(temperature, pressure, humidity);

            _logger.LogInformation($"{DateTimeOffset.Now}:BME680: reading");
            _logger.LogInformation(
                $"{temperature.Celsius:N2} \u00B0C | {pressure} hPa | {humidity:N2} %rH");
        }

Expected behavior

I'd expect accurate data when trying to read from the sensor.

Actual behavior

The readings I get are wrong. The temp should be around 25 C

I forgot to set the sampling.

bme680.SetHumiditySampling(Sampling.UltraLowPower);
                bme680.SetTemperatureSampling(Sampling.LowPower);
                bme680.SetPressureSampling(Sampling.UltraHighResolution);

It works now.
