Hi, I'm interfacing Nucleo-L476RG with a UART Device. If I power off that devices, my Nucleo code freeze and I need to manually reset it. I need to power-on and to power-off the device and the Nucleo must continue to works.

Nucleo send through UART4 and receive with DMA from devices. Then Nucleo send to PC via USART2 for debugging. In UART4 there is Idle Line detect for receiving unknown length of data.This is my code: MX_GPIO_Init(); MX_DMA_Init(); MX_UART4_In...
