Oh, okay.
Let me explain from scratch.
You can develop BME688 based on two options: BSEC 2, BME68x API driver.
BSEC 2 is library including BME68x API. If you want to use AI Studio, you have to use BSEC 2.
BSEC 2 : https://www.bosch-sensortec.com/software-tools/software/bsec/
bme68x API : https://github.com/BoschSensortec/BME68x-Sensor-API
Currently, only forced, parallel mode are tested by us for BSEC 2. So if you want to use sequential mode, I'd like to recommend you to use bme68x API.
There are example codes.
Please let me know if you have any questions.
Thanks,
