STEVAL-STWINBX1 datalogger V2.2.0 - Python GUI does not work

[johngj]

I am using the STEVAL-STWINBX1 development board with the FP-SNS-DATALOG2 software V2.2.0.

When I try to connect using the Python GUI tool, it gets stuck at "Device Template Model Loading"....

I reverted back to V2.1.1 and the GUI tool works.

Is there a bug in this new release V2.2.0 ?

Hi @matteo_ronchi 

Now that i can use the GUI because i had to use the v2.2.0 instaead of v2.3.0, the ST BLE Sensor APP doesn't work because i don't have the lateste Fw version...

How can i work then? 

Thanks for the help!

Hello @FilipeLourenço 

We always strongly suggest using the latest version available for all the components involved in FP-SNS-DATALOG2 projects.

Some bugs have been solved and new features have been added both on the Python SDK and the firmware side, plus major bug fix involved communication with BLESensor app (not fully working with v2.2.0).

You can refer to the changelog available in the package Release_Notes.html.

So, I strongly invite you to refer to FP-SNS-DATALOG2 v2.3.0, updating both firmware and Python SDK.

Furthermore, use Python 3.12 (if not feasible, use at least 3.11) and BLESensor app v5.2.x (the most updated should be 5.2.6, today for Android only, iOS ongoing).

Best regards,

Simone

Hi @SimonePradolini,

Thanks for your answers, but previously in this topic i was told to use the V2.2.0 to use the GUI.

Does it work now with v2.3.0?

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
