Hi, Thanks for your inquiry. There is no configuration or calibration for BMI160 step counter. In BMI160 datasheet the step counter only has three modes: Normal mode with medium threshold, Sensitive mode with the lowest threshold and Robust mode with the highest threshold. Thanks. ... View more

Hi, It seems like you are using an Arduino MCU GPIO pin to witch on and off an LDO or MOSFET for BMI270 VDD and VDDIO, right? You may measure the voltage of those BMI270 GPIO pins after you switch it off to see if they are 0V or not. If yes, then you can switch on BMI270 again for initialization. Thanks.   ... View more

Hi, Thanks for your inquiry. On page 26 of BMI270 datasheet, you need to make CSB, SDX, SCX digital IO pins low before you switch off BMI270 VDD and VDDIO as shown below. After you power on BMI270 VDD and VDDIO again, you can bring those pins high. Then BMI270 will get a proper POR and be ready to go with the init function. Thanks. ... View more

Hi, Thanks for your inquiry. BME688 can be trained to detect specific VOC gases, but it cannot measure the level of the gasses. For example, you can refer to https://www.youtube.com/watch?v=4vdliMRtxBY about how to train BME688 to detect coffee using BME AI-Studio SW. But it cannot tell how strong the coffee is in the unit of ppm or ppb. It can only tell you "yes, coffee is present" or "coffee is not present". Thanks. ... View more
