SensorTile.box PRO : Record human activity and pedometer

[pierre63]

Hello, 

@Andrea VITALI,

After using the WESU board (https://community.st.com/t5/mems-sensors/lsm6ds3-lis3mdl-calibration/td-p/762534)

we decided to move forward with the sensor tile box PRO. 

We want to record human activity recognition and pedometer information in the SD card, with a timestamp. 

We managed to record HAR and pedometer information separetly, on BLE or in a SD card file, but :

* If we add the RTC value (for timestamp) to the HAR example, we got the message FLOW_COMPATIBILITY_ERROR

* If we enable pedometer, adding gyroscope and accelerometer (60Hz, same as HAR example) in input, add HAR in function, there is no data in the SD card (only header in the csv file), and no updates in Bluetooth (event when SD_Log is updated in log status)

Is it possible to get timestamped HAR + pedometer data in a SD card file ?

Bonus : if We can also log raw data (ACC, GYR, MAG + BARO) at 240, 100 and 1Hz, that's will great.

For now, we can't use this eval board for our need.

PS : 

FW version : 1.2.0

brd name : STEVAL-MKBOXPRO

Please find attached : 

* the json for HAR + RTC Screenshot for the configuration.

PW = pedometer on wrist; advice is to also use AW activity recog on wrist, to reduce the number of false positives

PM = pedometer (generic position)

Hello @pierre63 , 

Glad to hear that it worked for you. MotionPW is designed for wrist worn applications. As mentioned by @Andrea VITALI it reduces the false positives if used with MotionAW. MotionPM is designed for belt-worn or generic applications. MotionPW should be the right choice for you. 

I have set the ODR for the sensor hub as 52Hz. The project should work for ODR >= 50Hz. Tried 160Hz that I think you had set for your project and it works.
