BME688 and Bosch-BME68x-Library on ESP32

[Gavin]

Hello, 

I have been using the BME688 with ESP32 in the arduino environment. I have tried relentlessly over the past few days to get a resonable reading for AQI using the Bosch-BME68x-Library however have really struggled. I have attached the arduino code I have made modified to use the I2C instead of SPI and a picture of the output.  I have tried many different operational modes to no success. 

I have seen other posts with similar output however all mention the use of the BSEC library which I feel is overkill just to get a reading from this sensor. 

Any help will be much appriciated. 

Thanks

Hi Gavin,

As you used BME688, you could run https://github.com/BoschSensortec/Bosch-BSEC2-Library/tree/master/examples/generic_examples/basic, then you could get IAQ value from BSEC2.

Hello, 

Thanks for the response. For this library it includes instructions for using the ESP32 package. I'm actually using a different package (WEMOS Lolin 32 -- https://randomnerdtutorials.com/esp32-built-in-oled-ssd1306/ ) and had difficulty making the changes suggeseted to the rone i'm using. Could you advise on how this could be made possible?

Thanks

Hi Gavin,

See it from your link, it also was ESP32 platform on Arduino IDE.
