Hi Robin, I strictly referred to the integration guide, while i needed to adapt the example code to my case because i am using a raspberry pi pico. The main problem is that i don't get any values for requesting the gas estimates. I don't even get zeros. One more difference is that when loading the configuration i cannot use the .config file because i get a version mismatch error, while i can load the .h and .c file, and i don't know if this changes something (referring to the BSEC_2.2.0.0_Generic_Release_30052022\config\bsec_sel_iaq_33v_3s_4d files). The workflow in my code is the one defined in the sequence diagram in the integration guide. EDIT: i checked the version of the bsec loaded by the pico through bsec_get_version and it is 2.2.0.0
