Thank you for your reply. 1. How can I collect the calibration parameters from the sensor, and once I boot my device back how can I write them back in the BSEC library? 2. Moreover, this process to save / load the calibration parameters improves the calibration time, but will this given calibration still correct if I change my environment? For example : I calibrate the sensor in an office first, then I store the calibration parameters (once at IAQ acc = 3), I power off my device, and at the next boot in another environment (for example : outside) I load the previous calibration parameters to improve the calibration time. Will these calibration parameters still good? I mean, is it ok to make an initial calibration only once, then store it, and at each new boot load it into the BSEC library whatever the environment? Or does the BME680 need to re-calibrate itself according to this new environment if the give, calibration parameters are too different than the actual environment?

Hello, I'm trying to work with the BME680 in a really fast and punctual way. Use case : the user powers-on the device, may wait for 5 minutes (e.g. the time to go from an IAQ accuracy of 0 to 1), but then when can they expect to have relevant values (e.g. passing from an IAQ accuracy of 1 to 2, and then 3)? 1. The calibration is quicker when agitating a COV source (whiteboard marker, essential oils...) near the sensor, but it may last up to 20 minutes... Is there any protocol that could guarantee to the user a quick calibration in a fixed time, in order to obtain a measure quickly after power-up? 2. Moreover, after powering-off the device, in the same working environnement, would it be possible at the next power-up (use case : only few minutes after power-off) to by pass these 5 minutes of "boot" (e.g. the time to go from an IAQ accuracy of 0 to 1), and load the previous calibration data?
