Hello @AlfRomeo
You are switching to EXTI and entering STOP mode in a while loop. The MCU goes to STOP mode and will wake up if an EXTI interrupt occurs. After the execution of the EXTI IRQ handler, it will return to the main loop and re-enter STOP ...
Hello @AlfRomeo
I updated my code to switch from RX USART configuration to EXTI configuration. The MCU go to STOP2 mode and wakeup correctly.
Please find attached my code.
Hello @AlfRomeo
I tried to configure EXTI interrupt, on RX UART pin with NUCLEO L4 board, to wake up the MCU. The MCU enter and exit the STOP2 mode successfully.
Please find attached my code.
