    BME68x gas_wait Purpose

    BME68x gas_wait Purpose

    I've been reading through the BME688 datasheet and the BME68x API and am confused about the purpose of the Gas_wait registers. From what I can tell, the res_heat values are fully calculated using a target temperature and the sensor parameters. If this sets the target resistance for a target temperature, what is the purpose of the gas_wait register? Does it take a significant amount of time to heat up and therefore other values (TPH) can be evaluated during this period?

    Thanks for any clarification!

    Hello cweaver,

    This is necessary configuration for the heater.
