    BME280 Data to test Calculations


    Could someone please send me some the raw calibration values, and the raw register values for the Temperature/Pressure/Humidity for the BME280.

    With also the correct calculated Temperature/Pressure/Humidity readings?

    I would like to test my calculations as I think my pressure calculations are incorrect.

    Re: BME280 Data to test Calculations

    Thanks for the link. I had seen (and used) the excel form already. What I needed was the Raw (Hex) data which is returned from the BME280, unfortunatley the sheet does not have this.

    The issue I have is that the BME280 returns a high pressure reading, the form also shows this so it is not my calculations. Is the sensor faulty?

    The temperature is correct, and humidity I don't have anything to check against.

    The Raw values are:


    0x6C, 0x6E, 0x77, 0x66, 0x32, 0x00, 0xA8, 0x92, 0x27, 0xD5, 0xD0,
    0x0B, 0x6F, 0x18, 0xCA, 0xFF, 0xF9, 0xFF, 0xAC, 0x26, 0x0A, 0xD8,
    0xBD, 0x10, 0x4B, 0x65, 0x01, 0x00, 0x14, 0x0B, 0x00, 0x1E


    0x55, 0x33, 0x80, 0x81, 0x7F, 0xB0, 0x79, 0x13

    Calculations are:


    Settings are:

    0xF5 = 0b10101000  ' Config Setting (1000ms Standby, IIR Filter @ 4)
    0xF2 = 0b00000010  ' Humidity Setting (x2 Oversampling)
    0xF4 = 0b01001011 ' Temp/Pres Settings (x2 Oversampling, Normal Mode)

    Do my settings/data look correct?

    Could it be a faulty sensor, or am I missing something?

    Hi Badger,

    The data that you provided does not specify which value corresponds to which calibration register. I could not decode the calibration data.
