Hi Sir: Please see the follow comments: 1. Accurcay 2 means medium accuracy, sensor calibration may improve performance, but it can be used as well. Accuracy 3 means high accuracy, it is better than accurcay 2. 2. If sensor is in a stable environment, the device will be able to self-calibrate in a short term. Ambient changeis extremely important for sensor calibration. So it was acceptable and reasonable to calibrate for more than 2 days if no external intervention. 3. state_load load history baseline data, it is from state_save() store. The config data is loaded is located at config_load() function (uint8_t bsec_config_iaq[454]) . 4. Yes, "generic_33v_300s_4d" is the right configuration for me 5. BESC algorithm is auto-fit different platform, if you want get integer data, maybe you should change output format. So in the example only float is used. 6. It is better to post it in new topic if you have new question. Thank you for choosing BST BME680 and look forward to serving you again.
