BME680: is it possible to read all sensors every minute by using ULP plus?

[tomjones]

Is it possible to use the "ULP plus" mode to get values of all the sensors (temp, humidity, gas, IAQ etc) at a regular interval of, say, 1 minute? 

Are there any drawbacks of using the sensor this way? Does it produce the same quality of results as in the standard modes of operation?

Hi @tomjones, 

Sorry for confusing. I talked about BSEC2. 

For BSEC ULP+ mode, you can ULP Plus mode and trigger data additionally, but below comment you have to consider. 

The minimum sample interval for ULP+ is 60 seconds.

That means,

- The ULP+ trigger is not allowed when the timestamp is within 60 sencods before normal ULP trigger

- The ULP+ trigger is not allowed when the timestamp is within 60 sencods after normal ULP trigger

Also, as you can see, you have to use 3s config file, not 300s config file. 

There is no drawback, but current consumption would be higher than normal ULP mode. 

60s interval case,  I have one concern. Due to system delay + our requirement (60s interval before after ULP trigger), you might not exactly trigger every 60s since it might be some system process time from your side. Like 100s is safe. 

Thank you.
