failing to connect to the WB55 Nucleo using the STM32CubeMonitor-RF

[fmunoz]

Hi, 

I flashed the nucleo-stm32wb55RG with the binary BLE_TransparentMode_reference.hex (location: C:\ST\STM32CubeWB_package\STM32CubeWB\Projects\P-NUCLEO-WB55.Nucleo\Applications\BLE\BLE_TransparentMode\Binary) using the STM32CubreProgrammer (version 2.20.0). I followed the instructions of UM2288 Rev 19, section 2 (connection to target). But in STM32cubemonitor-rf, when I click 'connect' button, I get a pop-up message: 'Device under test not responding COM port closed'.

Before flashing BLE_TransparentMode_reference.hex, I installed stm32wb5x_FUS_fw.bin and stm32wb5x_BLE_Stack_full_extended_fw.bin using the STM32CubreProgrammer. Here is the screenshot showing the FUS and stack versions:

The device manager shows COM3 for the nucleo-wb55:

However, I am not able to connect to the nucleo using the cube monitor-rf tool as shown below:

 Can you please provide further guidance to fix this issue? 

Thank you

Hello @fmunoz 

Could you please try to:

• Connect the board to the STM32Cube programmer V2.20.0.
• Click on the button ‘Read FUS infos’.
• Click on the button ‘Start Wireless Stack’.
• Open the BLE_Transparent mode example From the STM32CubeWB V1.23.0 using the STM32CubeIDE V1.19.0.
• Compile and upload the code to your Board.
• Open the STM32CubeMONITOR-RF V2.18.0. 
• Set the correct COM port and set 115200 as baudrate.
• Click on Connect button.

That should work.
Best Regards.
