STM32WL5MOC use LPUART for wake up from STOP2

[matteverze]

Hi, 

I started from the LoRaWAN_End_Node example to develop a custom application with a STM32WL5MOC module. I would like to modify the example such that I can wake up the MCU from stop2 mode when I received some data on the lpuart . I set LSE as clock for LPUART1. I found some example on the community but they didn't for on my STM32WL5MOC. Someone can explain how to setup the LPUART?

Thanks.
