STM32WB Dongle Uart Issue

[EBuss.1]

Hey,

unfortunately the dongle is no longer recognized as a serial port when i load one of my projects onto the device. When I use the example applications, it works fine. Any idea what this could be.

Thanks in advance

Hello,

To use USB, it requires a semaphore which you need to set yourself. See : Building wireless applications with STM32WB Series microcontrollers - Application note Chapter Shared peripherals (Figure 9. Algorithm to use USB on CPU1). You can look PeriphClock_Config function in P-NUCLEO-WB55 USB Dongle example (e.g BLE_TransparentModeVCP) .
