STEVAL-MKBOXPRO Python SDK installation issue - v2.2.0 vs v2.3.0

[FilipeLourenço]

Hi @matteo_ronchi 

I am using the STEVAL-MKBOXPRO development board with the FP-SNS-DATALOG2 software V2.2.0, and i already checked that i have all the right versions of 

• st_pnpl v2.3.0
• st_dtdl_gui v2.3.0
• st_hsdatalog v3.3.0

However, i am still getting the message "Device Template Model Loading".

Do you have any other recommendations?

Thanks

Hello @FilipeLourenço 

Consider that the topic started on ‎2024-08-02, where v2.2.0 was the latest version available.

Generally once a newer version is available, I encourage you to update the software.

If by using v2.3.0 you'll see some issues or for further support, please open a new thread, so that we can restart with a clean discussion.

Best regards,

Simone

Hi @SimonePradolini ,

I just replied to an old topic, i had the v2.3.0 installed and i was getting an error "Device Template Model Loading".

And another ST employee told me that i must use the v2.2.0. Then, after a lot of work, everything worked, but now i can't work with the mobile APP. Sorry to insist, but this situation it's frustrating. 

Thanks!

Hello @FilipeLourenço

Citing your very first entry, you said "I’m using the STEVAL-MKBOXPRO development board with the FP-SNS-DATALOG2 software V2.2.0". That's the reason Matteo supported you on the specific version.

The "Device template Model loading" error was because you were using the firmware from v2.3.0 on the Python SDK from v2.2.0. 

In fact, once we explained to you how to use STM32CubeProgrammer properly, you succeeded flashing the firmware from v2.2.0 and everything started working fine.

Your request seemed focused on the specific v2.2.0, maybe we misunderstood your original request, I'm sorry for that. We did the best we could to let you have v2.2.0 working on your hardware setup.

As I already said in a previous comment, v2.3.0 also includes a major bug fix related to the communication protocol with BLESensor app. 

If your goal is to exploit all the functionalities exposed by FP-SNS-DATALOG2, I strongly invite you to refer to FP-SNS-DATALOG2 v2.3.0, updating both firmware and Python SDK. You'll see BLESensor working fine.

If instead you’re limited on using the v2.2.0 version for any reason, I'm sorry, but communication with BLESensor won't work.

Best regards,

Simone

Hello @SimonePradolini 

Ok, maybe i misunderstood everything , i know that i changed FP-SNS-DATALOG2 software versions, but didn't understood that it has Python SDK versions too.

How can i update the Python SDK? The  FP-SNS-DATALOG2 i already changed previously as i know.

I just wanted to get Python GUI to work, to get real time plot data, because my SDcard was giving me files where the data was not fine. Then, with GUI, i realised that even saving in the laptop the data stayed corrupted. So i think that was the conversion program(.dat to .csv) fault, because i wasn´t using yours program that cames in examples.

Then i discovered the hsdatalog_data_export.py but i am getting a lot of errors like this:

I already had the same problem with the module click, but i managed to install it on PyCharm and was fixed. But with this specific modules from Python SDK i don't know what to do.

Can you help me with that?

Best Regards

Filipe

Hello @FilipeLourenço 

First did you already read README, Quick Start Guide, and User Manual? Those documents are essential to understand how FP-SNS_DATALOG2 works and how to install the Python SDK.

The above errors mean that you didn't install the SDK. See the log in PyCharm: if the script you launched isn’t finding 'st_datalog', it means that you didn't install it.

Are you familiar with Python? I suggest you make this experiment and reinstall HSDPython_SDK from scratch:

• Download FP-SNS_DATALOG2 v2.3.0 and use the latest SDK.
• Unzip it and open a terminal in your HSDPython_SDK folder.
• If you don't like to do that, open a terminal in your HSDPython_SDK folder (from your log I guess the path is C:\Users\filip\STM32CubeFunctionPack_DATALOG2_V2.2.0\Utilities\HSDPython_SDK).
• Create a virtual environment (all references here).
• Launch programmatically HSDPython_SDK_install.bat (launch the command in the prompt by typing HSDPython_SDK_install.bat.

You'll see all dependencies automatically solved with no error messages and you should be able to use the HSDPython SDK.

Simone
