Hi @Luigi Bibbo´​ ,

About your question, there are a lot of sensors on the B-L475E-IOT01A platform, and some of them can be linked to indoor navigation: inertial IMU (LSM6DSL) for the (pedestrian) dead reckoning, 3-axial magnetometer for the absolute direction recognition and eCompass application (LIS3MDL) and pressure sensor (LPS22HB), for the height (floors) estimation. Here you can find the theoretical aspects of these algorithms, while for source code you could find hints at this st.com page, or contact sales and representatives from you geographical area.

Moreover, on top of the sensors there is also a 802.11 b/g/n compliant Wi-Fi module onboard for Cloud communication.

Hello Eleon,

thank you for your reply. I need wearable sensors. How can I make B-L475E-IOT01A wearable ?

Best regards

Hi Luigi,

there is no official 3D box for lodging the B-L475E-IOT01A board in a wereable case, but you could use this other tool's STL file: "STEVAL-MKSBOX1V1 Alternative box cover to use as a wearable on the user wrist for 3D Printer (STL)".

The B-L475E-IOT01A dimensions are 7cm x 4cm, while the SensorTile.box is about 6.5cm x 3.5cm. So, the B-L475E-IOT01A is a littel bigger than the SensorTile.box, but you can modify and adapt it if you have a CAD tool...
