I have exactly the same problem as Desh: This is the output of the Basic example "basic.ino" with my ESP32 Board: Temperature, pressure, humidity and gas values give reasonable readings, but IAQ, Static IAQ, CO2 equivalent and breath VOC equivalent never change! What is wrong here? BSEC library version 1.4.8.0 Timestamp [ms], raw temperature [°C], pressure [hPa], raw relative humidity [%], gas [Ohm], IAQ, IAQ accuracy, temperature [°C], relative humidity [%], Static IAQ, CO2 equivalent, breath VOC equivalent 87, 22.17, 95529.00, 35.35, 109908.00, 25.00, 0, 22.17, 35.35, 25.00, 500.00, 0.50 3087, 22.19, 95529.00, 35.25, 109908.00, 25.00, 0, 22.13, 35.36, 25.00, 500.00, 0.50 6086, 22.22, 95527.00, 35.16, 118124.00, 25.00, 0, 22.16, 35.22, 25.00, 500.00, 0.50 9087, 22.25, 95527.00, 35.06, 124443.00, 25.00, 0, 22.19, 35.09, 25.00, 500.00, 0.50 12086, 22.27, 95527.00, 34.99, 131786.00, 25.00, 0, 22.21, 35.01, 25.00, 500.00, 0.50 15087, 22.28, 95529.00, 34.92, 136179.00, 25.00, 0, 22.22, 34.95, 25.00, 500.00, 0.50 18086, 22.29, 95529.00, 34.87, 138889.00, 25.00, 0, 22.23, 34.90, 25.00, 500.00, 0.50 21087, 22.32, 95529.00, 35.11, 140050.00, 25.00, 0, 22.26, 35.11, 25.00, 500.00, 0.50 24087, 22.32, 95531.00, 35.47, 144521.00, 25.00, 0, 22.26, 35.50, 25.00, 500.00, 0.50 27087, 22.33, 95531.00, 35.46, 147447.00, 25.00, 0, 22.27, 35.50, 25.00, 500.00, 0.50 30086, 22.34, 95529.00, 35.37, 150090.00, 25.00, 0, 22.28, 35.42, 25.00, 500.00, 0.50 33086, 22.34, 95529.00, 35.28, 153670.00, 25.00, 0, 22.28, 35.34, 25.00, 500.00, 0.50 36087, 22.35, 95531.00, 35.17, 156250.00, 25.00, 0, 22.29, 35.23, 25.00, 500.00, 0.50 39087, 22.36, 95529.00, 35.36, 149287.00, 25.00, 0, 22.30, 35.42, 25.00, 500.00, 0.50 42087, 22.36, 95529.00, 36.97, 148889.00, 25.00, 0, 22.30, 37.05, 25.00, 500.00, 0.50 45087, 22.37, 95529.00, 37.26, 152273.00, 25.00, 0, 22.31, 37.34, 25.00, 500.00, 0.50 48086, 22.37, 95531.00, 37.12, 153670.00, 25.00, 0, 22.31, 37.21, 25.00, 500.00, 0.50 51086, 22.38, 95529.00, 36.86, 156104.00, 25.00, 0, 22.32, 36.95, 25.00, 500.00, 0.50 54087, 22.39, 95531.00, 36.62, 158019.00, 25.00, 0, 22.33, 36.70, 25.00, 500.00, 0.50 57086, 22.39, 95529.00, 36.41, 160134.00, 25.00, 0, 22.33, 36.50, 25.00, 500.00, 0.50
