How do we get the reading from the BME680 BSEC to give these ?
BSEC_OUTPUT_CO2_EQUIVALENT = 3, /*!< co2 equivalent estimate [ppm] */
BSEC_OUTPUT_BREATH_VOC_EQUIVALENT = 4, /*!< breath VOC concentration estimate [ppm] */
In my implementation (well a github user with a compile for the Raspberry Pi to give reading at the CLI) setting the CO2_EQUIVALENT in the output message just gives 0.00
Any clues, everything else seems to be for before these whre introduced to BSEC.
Currently with 188.8.131.52

BSEC works on subscription-based model, therefore for the data to reach your output message you would need to make sure you have first subscribed to it. If your project is based on our sample code (bsec_integration.c), subscriptions are done in the function bme680_bsec_update_subscription(), which does not enable the eCO2 and bVOCeq outputs by default.
Updating the bme680_bsec_update_subscription() function with your desired virtual sensors should make them appear in your output message.
can you subribe a little bit more in detail?
