SPI or serial port?
If it weren't for those two, Then why must the MCU_API_delay() function be set while ((LL_USART_IsActiveFlag_TXE_TXFNF(USART1) == RESET) || (LL_USART_IsActiveFlag_TC(USART1)) == RESET)) {};
We can use both uart of MCU, so I want to confirm with you whether it is necessary to configure here.

See the datasheet - they communicate via the Bus Matrix:

thk's,
That's the MRSUBG in STM32CubeMX.
uart non-SIGFOX must be configured.

Hello @KiteLee
Could you specify the exact question you are asking? Is it about the Radio or the Sigfox?
Best Regards.

Still no idea what your actual question is now!
Has your original question, "How do stm32wl33 CPU and the sub-1GHz wireless (Radio) communicate?" been answered?
If so, please mark the solution. Then you can start a new thread for a new question.
If not, please explain clearly what you're missing.
