Hello everyone! I am working on a project to interface BME688  with nrf52 chip, I am using BSEC lib v2. I am able to read data from the sensor, to validate my data whether I have corrently interface the sensor or not, for this reason I have used another MCU ESP 32S , A example code is provided in library pakage I have used the example code.  while comparing the data for two MCU's  from the sensor, strangely I found that all the readings are similar except Gas Resistance.  as you will see in screen shot. The ouput for both MCU is attached here with question. I found that ESP-32S showing high gas resistance compare to the NRF52. bsec_serilized_configuration_iaq.h is used for both MCU's. I am unable to find the reason for this, what could be the possible for reason for this conflict? Thanks. Debug output:   ... View more

Hi, I was looking to the datasheet of BME 680, At page : 8|60 in Table 2: Gas sensor parameter specification, and I was unable to get understand on the Response time (brand new sensor) in different modes of operation of BME 680 sensor, So if you could help me to understand of this concept, like what exactly this means. Thanks     ... View more

Hello Bosch! I have running multple BME680 sensors which are currently report data, and I found that some sensors have drops their Static IAQ values to "zero" when the IAQ Accuracy is set to "1", is this behaviour is normal , as you can see the Image below,  I am currently using LP mode of sensors. After 5 mins the IAQ accuracy is set to "1" for all sensors but some sensors have drop their Static IAQ value to "0". Thanks ... View more
