STM32WLE5 custom board wake up from sleep/standby on radio

Hi, I have a custom board equipped with a STM32WLE5 based module for LoRa transmissions. I am able to manage the processor in various low-power modes and wake it up by pins and/or RTC. How can I configure the processor to wake it up by the sub-GHz radio? Is there a code example to start from?
Many thanks

Hello @Curro 

According to the table 37 of the RM0461-Rev10, the Radio-system (sub-GHz) have the wake-up capability up for low power modes up to Stand-By mode. For the examples, there is not such an example for standby mode for now, you can for example have a look at the LoRaWAN_End_Node application that enter and leave the STOP2 mod on the IDLE task.

Best Regards.
