Probably this discussion will help you.

Thank you, I had already read this discussion, but my doubts come after, with the stm32cube programmer. I haven't found any instruction on how to use it to program the bluetooth module.

Hi IVent.1 (Community Member)

Take a look at this videos for Nucleo-WB55, but it's the same with STM32WB5MMG Module.

Hi Romain,

I'm in this situation...the connection with the STM32cubeprogrammer is established, but in this way I have access only to the stm32u5...how to access to the stm32wb?

Hi IVent.1 (Community Member)

In your case, you have 2 STLink:

• One onboard on CN8 USB for U585 device.
• A second external connected on CN5 for STM32WB5MMG module.

If it's correct, you should inform STM32CubeProgrammer which debugger you want to use:

In disconnect mode, refresh Serial Number and chose the correct STLink Serial Number to use.

An example below:

Hi Romain,

I have a second external stlink connected to the CN5 (the Device Management of the pc shows both the 2, ST-Link Debug and STM32 STLINK), but STM32CubeProgrammer shows me only the ones of the main board.

Hi IVent.1

If after refresh icon You detect only onboard STLink on U585, you have to check hardware connection between your computer and the external STlinkv2 plugged on CN5.

Confirm if the USB cable is a data version (and not a only charger version) otherwise change STLinkV2, change USB port.

If you are using Windows OS, you can check in Device Manager if STLinkV2 appears in USB Device list.

When your operating system will detect both STLinkV3 onboard and STLINKV2 external then STM32CubeProgrammer will list them.
