VOC reading using BME 688 and ESP-32 S2 TFT

[Diogo_Goto]

Hello,

I have an Adafruit ESP 32 S2 TFT (https://learn.adafruit.com/adafruit-esp32-s2-tft-feather/overview) and a BME 688 breakout board by Adafruit, I am programming in the Arduino IDE.

I am trying to get a reading of the VOC concentration, I am able to get the raw gas resistance, but when I tried the BSEC Software Library provided by Bosch I wouldn't compile, then I found this other library, bsec2 library (https://github.com/boschsensortec/Bosch-BSEC2-Library),  that should support the MCU I have. However, when I tried the x8boards basic example it would give me error code -3. I also tried the generic basic example, but that would give me error code -2.

What do these error codes mean? is there any other way to get the VOC concetration?

Hi Diogo_Goto,

Thanks for your inquiry.
You can download latest BSEC 2.5.0.2 from https://www.bosch-sensortec.com/software-tools/software/bme688-software and try it again, the BSEC version on github is old.

Hello,

Is there any specific installation procedure? I added the extracted folder to my Arduino libraries folder but I can't find the library even after I restart the IDE there, I also tried importing the library by the add library zip button in the IDE, but it just said it isn't a valid library and I tried  modifying the platform.txt as instructed by one of the files inside the library folder but nothing change.
