A short follow up on the topic. There was a bug in my code that didn't allow for the get data to retrieve the right values, and the estimeates weren't changing because of that. After having fixed that i'm having the same problem exposed in this post. I tried running the basic_config_state.ino on the devkit and with SENS_NUM = 0 the results are right If i change SENS_NUM to 5 you can see how the sensor needs a couple of readings to get to the correct result With my configuration running with an adafruit board with the sensor installed on it and a raspberry pi pico this doesn't even happen, the readings are wrong, even if i switch from bsec2.2.0.0 to bsec 2.4.0.0 Did anybody face the same issue and solved it even if with another board?   ...

I don't get any version mismatch error on this because i know that the generated configuration with BME AI Studio must match the library version used in the implementation. So i generate a BSEC2.2.0.0 configuration and i use the BSEC2.2.0.0 library. After what you told me i switched to BSEC2.4.0.0 and i generated the BSEC2.4.0.0 configuration from the same algorithm. I am using BME AI Studio v2.0.0. To reinforce what is my problem:  I have a single BME688 sensor on an Adafruit board connected to a Raspberry Pi Pico with I2C that runs the BSEC2.2.0.0 (and after your advice i switched to 2.4.0.0 making all the required adjustments). I take samples with the devkit and generate a configuration with BME AI Studio v2.0.0. for the selected bsec library. I then load the .c file (i also tried hardcoding the variable to avoid loading problems) and pass it to the bsec_set_configuration and check that the result of the operation is ok. Then when i go to the sensing part the result is stuck on 100% for the GAS_ESTIMATE_1 value even if i change the condition. Loading the same (always the right version) .c file in the .ino example for the devkit board gives me the right results when doing the sensing. The workflow of the code that i've written for the Raspberry Pi Pico is the one present in a previous answer on this topic ... View more

To my understandings by switching to the bsec2.4.0.0 in my implementation with a single sensor i should be able to get more accurate readings right? Because the devkit implementation of the sensing, based on the .ino example, works fine already. In the image below there is the output generated by the adafruit sensor connected to a raspberry pi pico: During the first "parallel mode" it was exposed to the environment while during the second one it was inside a jar with some cheese (the same one used for the sampling). As you can see the probability doesn't even flinch, and that's what makes me worry. As you can see in the image the version this time around is 2.4.0.0 (obtained through bsec_get_version, no cheating). I am attaching the .h and .c files for the configuration too, if someone wants to try. ... View more

Hi BST Robin, I am using the BME688 Dev Kit Software version 2.0.6 and the BME AI Studio version 2.0.0. ... View more
