    BME680 temperature value is always 0 after calc_temperature() is called

    I use a bme680 for my project, but the temperature value from `read_field_data()` is always 0 .

    I printed the following debug data for this code part https://github.com/BoschSensortec/BME680_driver/blob/master/bme680.c#L1223-L1239

    buf[5-7] is 129 105 96
    adc_temp is 530070, adc_pres is 393660, adc_hum is 14457, adc_gas_res is 304 and adc_gas range is 5
    after calculation:

    data->temperature = 0.000
    data->humidity = 20.270
    data->pressure =95598.000
    data->gas_resistance = 294021.0

    buf[5-7] is 130 140 32
    adc_temp is 534722, adc_pres is 414452, adc_hum is 13726, adc_gas_res is 377 and adc_gas range is 5
    after calculation:

    data->temperature = 0.000
    data->humidity = 16.673
    data->pressure = 92113.000
    data->gas_resistance = 276157.0

     

    Can somebody help me?
