Firmware on my STEVAL-PROTEUS1 board (STM32WB5MMG)

[pradeepaan]

Hello STM32 Community,

I accidentally erased the full firmware on my STEVAL-PROTEUS1 board (STM32WB5MMG). After that, I followed this process to recover:

FUS firmware: Updated using stm32wb5x_FUS_fw.bin from STSW-PROTEUS (since FUS was missing in the other package).

BLE Stack: Flashed stm32wb5x_BLE_Stack_full_fw.bin from FP-AI-PDMWBSOC.

OTA Reference App: Flashed Proteus_BLE_FUOTA_reference.bin from FP-AI-PDMWBSOC.

After these steps, Bluetooth worked fine — I could connect to the board via my phone.

However, when I upload the user application PDMWBSOC.bin (from FP-AI-PDMWBSOC), Bluetooth stops working — it gets disconnected and doesn’t advertise anymore.

I tried uploading the application using:

STM32CubeProgrammer

OTA method via the mobile app

In both cases, the same issue occurs.

My Goal: I want to use the FP-AI-PDMWBSOC software pack to run the predictive maintenance application via BLE.

Can someone please guide me on what might be going wrong or if any additional steps are needed after uploading PDMWBSOC.bin?

Thanks in advance!

Hello,

are you able to run the standalone user application PDMWBSOC without OTA app?

If you run debugging, is it stuck anywhere?

Hello ,

Thanks for the support. I was able to solve the previous issue.

Now, I’m working with the FP-AI-PDMWBSOC2 function pack. However, after uploading the firmware, the Bluetooth appears to be stuck. The blue LED stays on continuously without blinking, and the device is not discoverable over Bluetooth.

Could you please help me understand what might be causing this?

Best regards,
Vijay

yes.

Hello,

can you please share more information from debugging the project?

Is it stuck anywhere? Hardfaults?

Thanks.

Hello Filip,

No, I haven’t performed any debugging yet. I uploaded the default PDMWBSOC2.bin file from the .fp-ai-pdmwbsoc2 software package.
The FUS, BLE stack, and OTA files were placed as specified in the datasheet.

However, the default PDMWBSOC.bin file from the .fp-ai-pdmwbsoc package works properly without issues.
