Bluetooth version information for two MCUs wireless (stm32wb5mmg/stm32wb1mmc)

hello.
As I said in the title, I would like to know the exact Bluetooth version information for both MCUs.
I recognize the Bluetooth version of stm32wb5mmg as '5.0'. However, the datasheet and MCU website say that the Bluetooth version is '5.4'. Which version is correct?
I would also like to know the Bluetooth version information of stm32wb1mmc.
Is there a way to find out the exact Bluetooth version information?

 

The datasheet is attached, and below is the MCU website I checked.
stm32wb5mmg website:
https://www.st.com/en/microcontrollers-microprocessors/stm32wb5mmg.html

stm32wb1mmc website:
https://www.st.com/en/microcontrollers-microprocessors/stm32wb1mmc.html

You can change the version of Bluetooth in the CubeMX if i am not wrong. so stm32wb5mmg does support bluetooth version 5.4 and for stm32wb1mmc , It supports bluetooth 5.4 as well. all you need is, when you are doing settings for your project

Hello @KWOOJ 

As said @SikandarLF both STM32WB1MMC and STM32WB5MMG support both BLE 5.4. But, you can configure them to use even a lower version for maybe adaptation needs.

Best Regards.

Hello,

Please don't be confused between Bluetooth version and real Bluetooth features supported.
Every features are optional, meaning you can have a device Bluetooth 5.4 certified but supporting only features of 5.1 for example.

Please refer to Certification guideline for STM32WB and STM32WBA - stm32mcu for having latest certification version of stm32wb5mmg or stm32wb1mmc.

As can be seen here, STM32WB5MMG is having a 5.3 component QDID (187035) and can be combined with a stack version 5.4 (QDID 216169) so this module can be stated as bluetooth 5.4 (again does not mean it supports all 5.4 features)

STM32WB1MMC is having a 5.3 component QDID (187042) and can be combined with a stack version 5.4 (QDID 216169) so this module can be stated as bluetooth 5.4 (here again does not mean it supports all 5.4 features)

 

Regards

Laurent

    With your help, I have accurate information.
    I was able to set the Bluetooth version through CUBEMX.
    It helped me solve my problem
