We are using an STM32WB5MMG in a product, We needed to run a few BLE tests for compliance needs and came across the BLE transparent mode to help with BLE tests. 

In accordance with the ReadMe under BLE_TransparentMode inside STM32WB5MM-DK, we have undertaken the following steps 

  • Updated FUS to stm32wb5x_FUS_fw.bin at 0x080EE000
  • Updated soft device with stm32wb5x_BLE_Stack_full_extended_fw.bin to 0x080C7000
  • Modified BLE transparent Mode to change USART pins being used to PA9 and PA10 though Cube MX

The CubeMonitor-RF software refuses to connect with the device however

Hi Filip, 

On the fresh boards, the problem was because of not having started the wireless stack. It is now resolved 

Using the latest version of cubeProgrammer helped with not having to put addresses in manually 

I am yet to work on the older boards and will post an update once I revive them 

Thank you for all the help!
