HSDPython_SDK missing in DATALOG2_3.0.0

[Old_Geezer]

So I downloaded the new datalog2 demo zip file (early 2025)

Installed the bin file into my STWINBOX using STM32programmer and verified that file was the same as target 

I believe this version is a bit more stable at connecting to the iphone app ST_BLE_Sensor 5.2.4, using BLE.

However

* I managed to easily lock the stwinbox by pressing the [START] arrow button on the app's Sensors page. the middle green LED stopped blinking and was stuck in either on or off and comms was lost.

* The python lib was not present in the zip archive. I started the hsdatalog_GUI.py in datalog 2.3 instead and it had trouble connecting over usb. After connecting, it locked up on a "loading templates" window,. Here's the debug log:

Hello @Old_Geezer 

From v3.0.0, HSDPython_SDK has been removed from FP-SNS-DATALOG2 and it has been released as a separate product with the new part number STDATALOG-PYSDK.

The new Python SDK has been rebranded, completely redesigned and reshaped with new features. For example, the hsdatalog_GUI has been rebranded as stdatalog_GUI distributed in stdatalog_examplesgui_applications/stdatalog/GUI folder.

The error you reported depends from the SDK version you’re using: v2.3.0-based SDK can’t work with v3.0.0 firmware. v3.0.0 firmware needs STDATALOG-PYSDK. By installing the latest STDATALOG-PYSDK, the issue will be solved.

New references are available in the function pack Quick Start Guide, Release_Notes, and README files.

Detailed explanations on the brand-new Python SDK are available on the STDATALOG-PYSDK GitHub repository. Be sure to follow the instructions available in the How to use and How to install sections.

Best regards,

Simone
