BME680/688 heater duration time accuracy

[GaryM]

Hello,

I understand how to program heater duration (gas wait) tme for both the BME680 and BME688 to 1ms resolution, but I was wondering about the accuracy of the value. I don't see anything in the datasheets that specify that. I've also searched previous topics.

For example, if I program a gas_wait time to be 100ms, what accuracy (e.g. +/- 1ms) can I expect the heater duraction to actually be?  Is it +/- 1ms?

Thank you in advance,

Gary Marks

Hi Eldar,

Thanks for your inquiry.
The basic unit of heat duration configuration is milliseconds, and after register configuration, the sensor will execute normally. You can refer to the process description of force mode.
