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
