HI,
I set temperature oversampling as 8x , pressure as 4x , using the bosch BMP3 library with ESP32-S3 as host via I2C , not really sure why the final INT64 compensate pressure reading need to be divided by 100x100 in order to get the Hpa pressure value , by right it should only need to be divide by 100 to convert to Hpa as actual pressure value output,
By the way the BMP390 temperature reading is accurate as comparison is made against BMP280 read out.
