Hello Gideon, For tilt detection, do you mean w rist lift detection and wakeup MCU? BMI270 was used in many wearable products and had the function of wrist wear wakeup feature. ... View more

Hello Wela, BMI160 had many features(any motion, significant motion, step counter, tap, etc...) because of internal algorithm inside, internal algorithm was not open out, but you could use the output result of algorithm. In BMI160, it had step detector feature. For you application, if step event received you would know current activity status was not rest. If no step event, you could think current activity status was rest. This is my suggestion. You could refer more information from BMI160 data sheet. ... View more

Hello sunnyYang, You will see 0x59~0x6B registers were reserved in data sheet. If you set 400 Hz ODR and read data every 0.1 s. For high ODR application scenario, most application read RAW data with high spped(ms). Can your application accept reading data every 0.1 second? It is better to directly read RAW data if you set ODR with a high value. By the way, which communication interface(SPI or I2C) you use? ... View more

Hi GMarco_Utech12, I did test on BMP388 reference board with the following register writing values. BMP388 current consumption was less than 2uA. reg : 0x1B data:0x03 reg:0x1C data:0x00 reg:0x1D data:0x04 After writing register values, I also double check register value with register reading.   Could you read out register values to check them on your board? ...

Hello GMarco_Utech12, You should set a value(your acc_us, your acc_bwp, your acc_odr) to 0x40 for your application. By 0x40 register default value, acc_us was disable. acc_us should be set to 1 for low power mode. Please refer register configuration from data sheet: If you haven't used magnetomenter and gyroscope, you only needed to set them to suspend. If you want to use magnetomenter and gyroscope, you could set them to minimum current consumption according register settong from BMI160 data sheet.   ... View more
