Suppress advertisement for STM Microcontroller Blockset.

Since upgrading to 2026a, I keep getting the following nag/advertising message:

ST-Link debug probe detected. To use STM32 processors with MATLAB and Simulink, install the STM32 Microcontroller Blockset.

I assume it is because I have a Segger J-Link debugger attached to my machine (I'm not using it with STM32 microcontrollers, BTW).

Also, I don't have Simulink.

Is there any way to suppress this annoying message?

Where and how are you seeing/receiving this? That would likely be significant on how to stop it.

Perhaps there's a user preferences for contact/notifications on the vendor site for the debugger that could be turned off?

Thanks for the response.

The message shows up in the command window.

It seems to happen kind of randomly and fortunately seems less common in the last day or two. Hopefully it will quit nagging me.

I seriously doubt that the debugger itself is broadcasting any notifications (other than normal USB handshaking, of course).

Thanks again.

I was thinking maybe it was external from the vendor site...

Is there a hardware addon for the device somewhere visible? I see notices about wanting to add what are somehow thought to be missing modules on startup occasionally; usually with them is an option to ignore.

I don't suppose it's a hyperlink by any chance that would lead to the addon manager to turn it off.

If it continues to haunt, I'd venture to submit Mathworks as an official support request at <Product Support Page> on how to kill it; it may be an unintended consequence and given your case is a pretty small useage sample, it may have never been observed before.

Hi @Les Beckham,

Please take a backup, and then delete the 'STM32DeviceData.json' file located at the following path:

'C:\Program Files\MATLAB\R2026a\toolbox\shared\hwmanager\hwmanagerapp\devicedata'.

That should disable the device detection pop-up.

Thanks,

Aabha

Thank you @Aabha. That seems to have done the trick. I appreciate it.
