I believe that CUBEMX does not automatically generate the hw_uart.c file when trying to use the STM32_WPAN peripheral. I was following along with this tutorial and wished to use debug trace however it elicited the error undefined reference to `HW_UART_Transmit_DMA' as no implementation for the function existed.
In the example projects for the STM32WB available here, the hw_uart.c file is included.
