SensorTile.box PRO: No serial port (/dev/ttyACM0 or /dev/ttyUSB0) on Raspberry Pi

[kj711]

Hello,

I am working with the SensorTile.box PRO and trying to connect it to a Raspberry Pi 4B over USB.
On plugging the board into the Pi, it is detected in lsusb as:

Bus 001 Device 003: ID 0483:5744 STMicroelectronics Sensortile.box_PRO_Multi_Sensor_Streaming

However, Linux does not create a serial device such as /dev/ttyACM0 or /dev/ttyUSB0.
This means I cannot access the device over a standard serial interface (e.g., minicom, screen, or pyserial).

Additional observations:

• I attempted to communicate with the device using PyUSB on the Raspberry Pi.

• The device enumerates with an IN endpoint (0x81) and an OUT endpoint (0x06).

• When I attempt to send data to the OUT endpoint, I consistently get:

usb.core.USBError: [Errno 32] Pipe error

This suggests that the device expects a specific vendor-defined command format and does not accept generic bulk writes.

Questions:

1. Does the SensorTile.box PRO expose a CDC-ACM serial interface over USB, or is the communication handled only via a vendor-specific USB protocol?

2. If it uses a proprietary USB protocol, is there any documentation or SDK available to interpret the USB bulk endpoints directly?

3. Is there a way to configure the board’s firmware so that it enumerates as a standard USB serial device?

My use case is to stream sensor data from the SensorTile.box PRO to a Raspberry Pi gateway and then push it to the cloud.

Thanks in advance for your guidance.

Hello @kj711 

Which firmware is running onto SensorTile.box PRO? I guess you are referring to FP-SNS-DATALOG2.

If so, you are searching for STDATALOG-PYSDK, the Python framework designed for capture, processing, and visualization of data from DATALOG2 firmware. Here you'll find all the references for properly download and install it.

Best regards

Simone
