Bosch BME68X_IAQ power management

[Tiit]

Hi

Does Bosch BME68X_IAQ driver support power management? I can choose between 3 different measurement presets in CONFIG, but I would like to measure values in short (1..2 min) period and then put it to sleep.

Thanks..

Hello,

''Does Bosch BME68X_IAQ driver support power management?'' - I can not see anything related to power management in the source code. 

'' I can choose between 3 different measurement presets in CONFIG, but I would like to measure values in short (1..2 min) period and then put it to sleep.'' - Could you please explain a bit more about this? which 3 different measurements in CONFIG you are mentioning?

Hi,

I mean these:

CONFIG_BME68X_IAQ_SAMPLE_RATE_ULTRA_LOW_POWER=y -- sample from BSEC every 300 sec

CONFIG_BME68X_IAQ_SAMPLE_RATE_CONTINUOUS=y -- continuos samples from BSEC

CONFIG_BME68X_IAQ_SAMPLE_RATE_LOW_POWER=y -- sample every 3 sec

OK .. I see, that Bosch BSEC library has minimum rate every 300 sec.. maybe I cant go longer as that then.

But I think the chip is not going to sleep between the samples, or am I wrong (if there is no power management in the driver)?

Hello,

These configs only control sample rate. I got comment from the developer.

Unfortunately, that library only supports Bosch's presets. One would have to do code changes to achieve a burst measurement pattern. Not sure if that works well with Bosch's model though.
