Does STM32WBA52, with BLE interface enabled, lock usage of USART1 ?

Hi,

I'm using a STM32WBA52 for my application with necessitates three UARTs and the BLE Interface.

In my CubeMX configuration, I've desactivated any usage of TRACE or DEBUG, nevertheless, even in that case, when :

/* Init code for STM32_WPAN */
MX_APPE_Init(NULL);

is called, USART1 doesn't work anymore.

My configuration on CubeMX is :

If I unckeck "ADV_TRACE", the code doesn't compile anymore due to multiple rerferences to "stm32_adv_trace.h".

Is there any limitation of usage of u(s)art with the STM32WBA when BLE interface is enabled ?

When I read your doc (https://wiki.stmicroelectronics.cn/stm32mcu/wiki/Connectivity:STM32WBA_BLE_STM32CubeMX), however, it seems not :

Thanks a lot for your answers ... I'm a bit stuck at that point !!
