Hello, I am Using BSEC version 2.0.6.1 with a BME688 sensor and AI Studio version 1.6.0 on a Raspberry Pi. My goal is to read the gas estimate predictions from an algorithm that I have trained in AI Stuio. My setup is working when I use a BSEC config from the conf directory in the BSEC package. But as soon as I use the config (algorithm) that I exported from AI Studio, BSEC does not trigger measurements any more. I already checked that the versions match. First I initialize the BME688 sensor via the BME68X API from GitHub and the I initialize the BSEC. Then I set the config (the algorithm that I have trained) from AI Studio via the bsec_set_configuration function. Next I subscribe all 19 BSEC outputs using BSEC_SAMPLE_RATE_HIGH_PERFORMANCE via bsec_update_subscription. So far all functions return BSEC_OK. Then I call bsec_sensor_control, which returns BSEC_OK as well but in the bsec_bme_settings_t the process_data and trigger_measurement fields are 0. op_mode is 2 (BME68X_PARALLEL_MODE), run_gas is 1 and the next_call, heater_temperature_profile and heater_duration_profile match the expactations. So my question is: What could be reasons for process_data and trigger_measurement to be 0? Thanks for your answers.

I'm afraid I can't help you with your question, but I wonder how you managed to retrieve the values for BSEC_OUTPUT_GAS_ESTIMATE_X. Whatever sample rate I use to subscribe the BSEC_OUTPUT_GAS_ESTIMATE_X the bsec_update_subscription function returns an error. That's why I wonder if I really need to subscribe them explicitly or whether it is enough to pass the config that I received from AI Studio to the bsec_set_configuration function? If I get the BSEC_OUTPUT_GAS_ESTIMATE_X to work I will try to replicate the bug for comparison.

I have a similar problem using a BME688 ,BSEC 2.0.6.1 and the BME68X C API from GitHub Whenever I try to subscribe the BSEC_OUTPUT_GAS_ESTIMATE_1, bsec_update_subscription returns an error. I tried all the BSEC_SAMPLE_RATE macros as well as 1 divided by the duration of the heater profile. As I understand it, the sample rate is the amount of samples per second. Therefore for a heater profile with a total duration of 100 ms the sample rate should be 1000 ms / 100 ms = 10. But if i subscribe the gas estimate with this sample rate I recieve the error -12 by the bsec_update_subscription function. I have also recieved error -10. The sample_rate of the requested output (virtual) sensor passed to bsec_update_subscription() does not match with the sampling rate allowed for that sensor For testing I exported an alogrithm from AI Studio and I use the .config file to call bsec_set_configuration but the gas estimates are always at 0.0 with 0 acccuracy. So here are my questions Which is the correct sample rate to subscribe the BSEC_OUTPUT_GAS_ESTIMATE_1 etc. ? Do I need to call bsec_update_subscription if I am using a config that was generated as an algorithm by the AI Studio? Is there a way to extract the subscribed Outputs from the bsec config or the bsec state?

I just noticed, that the heat compensated temperature is constantly at around -4 degC which is very unrealistic. The raw temeperature is at around 29 degC which matches the weather prediction for my location. Might this be a hint for what is going wrong? Besides I'm not using a statefile for the moment and I checked the timestamps, they seem plausible. Still the iaq accuracy is always at 0 even after hours of running in Low Power Forced Mode

I'm running the sensor in Low Power mode.
