getOversampling()

oversamplingRate = getOversampling(sensor);

This returns the oversampling rate for one of the 3 different sensors on the BME280. The "sensor" parameter can be specified using an integer value as below or using the enumerated type:

Use 0 or the enumerated variable TemperatureSensor
Use 1 or the enumerated variable HumiditySensor
Use 2 or the enumerated variable PressureSensor

The current oversampling rate is returned as an unsigned byte with the following numeric or enumerated type values:

0 or the enumerated variable SensorOff when sensor is turned off
1 or the enumerated variable Oversample1 for no oversampling
2 or the enumerated variable Oversample2 for 2x oversampling
3 or the enumerated variable Oversample4 for 4x oversampling
4 or the enumerated variable Oversample8 for 8x oversampling
5 or the enumerated variable Oversample16 for the maximum 16x oversampling

Any value other value is ignored.

Example:

BME280_Class BME280;  // Instantiate class    
...    
while (!BME280.begin()) {                          // Find on I2C bus
  Serial.println("Error, unable to find BME280."); // Show error message
  delay(5000);                                     // Wait 5 seconds 
} // of if-then we can't initialize or find the device
BME280.setOversample(TemperatureSensor,Oversample16); // 16x sampling to temperature
uint8 deviceMode = BME280.mode(NormalMode); // Set normal mode
...
Serial.print("Oversampling for the temperature sensor is ");
Serial.println(BME280.getOversample(TemperatureSensor);
