Using printf to output a large array cause the program to freeze

2025-01-04
When I use the UART_Printf example to output an array of size 1024 (or larger) via printf, the program seems to freeze and doesn't output any information after being downloaded to the STM32WB55 Nucleo board. However, when I reduce the array size to 6...

printf cannot output BLE debug information.

2025-01-02
Why can't my WB55 P-NUCLEO board print BLE debug information via UART? Some configurations, such as CFG_DEBUGGER_SUPPORTED, CFG_DEBUG_BLE_TRACE, and CFG_DEBUG_APP_TRACE, have been enabled. I tested it, and it seems the printf function is not working....

I am unable to connect the microcontroller to STM32CubeProgrammer, Keil, or other software via ST-Link

2024-12-14
In order to test the BLE performance of the STM32WB55CGU6 in STM32CubeMonitor-RF, I downloaded the BLE_TransparentMode program onto the STM32WB55CGU6. However, I did not notice that the pin configuration of this program did not enable Serial Wire. Th...
