STM32WL LoRaWAN : How do I go into STANDBY mode instead of STOP2 mode?

[LLr.1]

Hi,

Thanks to a previous question and the very clear answer of an ST employee. I understood the idea of the example LoRaWAN_End_Node and that it was not necessary to re-write the falling asleep but to use the one already present. (here Custom sleep and wakeup system on the lora end node STM32WL · Issue #10 · STMicroelectronics/STM32CubeWL (github.com) ). But, I would like to use STANDBY mode instead of STOP2 mode. My goal is to send only one message a day.

Why is standby mode disabled?

Thank you by advance

I think : You have to put UTIL_LPM_ENABLE instead of UTIL_LPM_DISABLE

But the "off" mode can be Standby mode or shutdown mode
