Bme688 operates in forced mode,What is the appropriate interval between two acquisitions

[yang2024]

hello ：

bme688 operates in forced mode,I tested and found that if the interval between two acquisitions is too short(200ms), the temperature display is not accurate, and the gas resistance values obtained from different intervals are also different. I want to know how long the interval between two acquisitions is appropriate?

Hi yang2024,

1. The force mode does not limit the interval between two force modes. The official force mode example on BME688 on Github(https://github.com/boschsensortec/BME68x_SensorAPI/blob/master/examples/forced_mode/forced_mode.c) uses a delay time of approximately 143ms.
2. We recommend using the compensated temperature and humidity values output by BSEC, as the RAW temperature and RAW humidity values obtained from the sensor API are not compensated.
