Getting BSEC2 Library data values from BME688 dev board

[koe]

Hi,

how can I get with developer kit output of values for  IAQ, sIAQ, CO2_eqivalent or Breath_VOC_Equivalent as provided by BSEC2 library.

When logging data with bme68x_demo_sample on BME688 dev kit (v1.5.0), I only get a ".bmerawdata"-log file with raw data for resistance gassensor from bme688 ". This I could input to BME AI-Studio, but there I do not see option for conversion.

Hi Koe, 

You can use BME688 dev kit and Arduino to generate data. 

Please check our github

Thank you.

Hi Minhwan,

thanks for the reply. Yes this is, what i tried, but up to now I only get BME688 raw data logged to SD card (by bme68x_demo_sample.ino)  but not the processed BSEC data. Do you have an example how to log the BSEC as well?

Thansk a lot.

Hi Koe, 

bme68x_demo_sample.ino is the same example code for our AI studio. 

Using bme68x_demo_sample.ino, you could save the raw data and use and train the data using AI studio. 

So, once you train your own config file using AI studio, you have to use examples in x8_board_examples.

We don't have other examples for SD card itself, but I think you can find some example code some online, currently we are using SdFat library. 

Please let me know if you have further qeustions. 

Thank you.
