We have been using BMP280 and BME680 both to measure the preassure. Both are using BOSCH library. Found that BMP280 has some Glitch(Spikes) on Pressure data but BME680 doesn't produce any spikes. FYI, I have checked temperature on the same BMP280, It doesn't have any Glitch. May i know that reason for those spikes?
Thanks

Hi,
Thanks for your inquiry.
It seems like a bug in BMP280 API source code on the Github. Please check if you are using the latest version.
In addition, you can use the attached "sample_calculation_BME280.xlsx" to manually input BMP280 parameters in the NVM and the raw data of temperature and pressure to calculate the final temperature and pressure. If the result from the Excel file is normal while the result from API code shows spikes like 1181.94hPa, then it means that the API has bug.
Thanks.
