Hi handytech, Acutually, I can't remember for how long I kept it running continuously in LP mode. I mean I am not sure if I left it running for more than 5 mins without interruption. But, I will try to leave it running for more than 5 mins and see if it moves or not. Thank you so much for the information and your quick response. Just another question, is it always necessary to leave the BME680 working for more than 5 mins, in LP mode, before having the real readings on the IAQ ?, or is it just needed for the first time when someone uses the BSEC ? And during those 5 mins, how accurate are the other variables (temperature, humidity, pressure. etc.) ? Thank you again and looking forward to hearing from you.

Greetings Bosch Community, Recently, I have been using the BME680 sensor to detect the quality of the indoor environment. And as per the documentation provided by Bosch, the BSEC converts the output data (resistance-Ohm) of the MOS Gas sensor of the BME680 to an IAQ that ranges between (0) and (500). Also, the software solution helps compensating the output data of temperature, humidity and pressure sensors. After implementing the BSEC in my project, I noticed some problems in the results that I was receiving from the sensor: - The resulted data from the temperature, humidity and pressure sensors was changing each and every 3 seconds (the default configuration) and the values were reasonable. Except for the IAQ which was stuck at the value 25 ('iaq_accuracy' = 0, 'static_iaq' = 0) without moving, even when the gas resistance and the other values were changing frequently (the sensor was tested in different conditions and it kept delivering the same IAQ value). - The gas resistance and the pressure variables were declared as floats but the received data was always an integer. - On the same condition, the gas resistance kept rising each and every 3 seconds without stabilizing at a specific value. I am using the STM32F091CC and GCC as a compiler. I am looking forward to hearing from you and I appreciate your quick response. Best regards.
