STM32WBA52 BLE Support

[rajdeep_01]

Hi @STTwo-32

Given that the distinguishing feature of STM32WBA52 is BLE and considering that connectivity applications support was removed since SDK V1.2.0, could you please clarify if this implies that there will be no further support for connectivity applications for the STM32WBA52 family in the future? If so, would it be advisable for users to consider transitioning to another family for future projects?

Your insights on this matter would greatly assist us in planning for potential future production needs.

Thank you for your attention to this matter.

Regards,
Rajdeep

Hello @rajdeep_01 

As you said, the coming versions of the STM32CubeWBA will give support to other components of the STM32WBA series except the STM32WBA52 Nucleo board. This one will not be supported anymore on the coming SDK versions. You can keep use all other STM32WBA boards (for example the STM32WBA55 boards) and STM32WBA52 MCUs.

Best Regards.

Hi @rajdeep_01 , @STTwo-32 ,

Let add a comment to previous answer

This is true that at board level, NUCLEO-WBA52 connectivity examples have been replaced by NUCLEO-WBA55 - STM32WBA55 is a "superset" of the STM32WBA5x family. 

At chipset level STM32WBA52 is fully supported by STM32CubeWBA cube package. It means that you can build a Bluetooth low energy project based on STM32WBA52 using STM32CubeWBA.  

Regards,

Sebastien.

Hi @Sebastien DENOUAL 

Thanks for update,
Yes, it's clear that direct example will not be available for STM32WBA52 family,
And possibility to implement based on example available for STM32WBA55 family,
But unfortunately, upon implementation in that way, facing weird issue:
- https://community.st.com/t5/stm32-mcus-wireless/stm32wba52cgu6-advertisement-issue-discoverable-in-ios-windows/m-p/707960#M20659

- Advertisement Issue: Discoverable in iOS/Windows not in Android:
- Board: NUCLEO-STM32WBA52
- MCU: STM32WBA52CGUX
- SDK: 1.14.0
- Due to unavailability of out of box any BLE example code for STM32WBA52 series,
  Used base code for STM32WBA55 series and converted firmware for STM32WBA52,
  Tried examples: peer_to_peer_server_ota, heartrate_ota and beacon.
- Found strange case for all three examples that:
  Device advertisement found in iOS(BLE5.3) and Windows(BLE5.0), with good RSSI around -26dBm to -34dBm,
  even able to connect, read, write and notify perfectly,
  But device advertisement not found in Android phones:
  MI-11X(Android-V13, BLE5.1), Nokia-G42-5G(Android-V13, BLE5.1)
