Let's say the sensor is turned off since last 2 days. If I turn on the sensor after that duration will it give me correct percentage of GAS_ESTIMATE_PERCENTAGE or I need to wait for sometime? If so how many hours I have to wait. Please mention these points.
You need to wait for BSEC accuracy to change to 3. See the integration guide document if you had downloaded BSEC2 package from official website https://www.bosch-sensortec.com/software-tools/software/bme688-software/
Instead of getting the gas accuracy level as 3 also the gas percentage is showing wrong. Sometimes the gas estimate percentage is reversed also. What is the reason behind it and on one circuit the Air Percentage coming as 4% when it was kept on Air and when it is placed inside coffee Beans it is showing 100%. Please help me out What is the reason for this behaviour and how to fix this issue?
