Sequencer stop when LPTIM1 Started

[jlaiosa]

I am using the LoRaWAN_End_node application.  The application was working fine until I integrated the Low Power sample code.  The Sequencer appears to stop working (I suspect the timers are not working).  If I do not do add MX_LPTIM1_Init() in main everything appears to work.  The problem is without the LPTIM1 I can not wake up the processor.

 

HAL_LPTIM_Counter_Start_IT(&hlptim1,(2000 * LSI_VALUE / 1000)); 

HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFI);

 

Thanks for the help.

Hello @jlaiosa 

To enter and exit low power modes on a LoRaWAN application based on the STM32WL. I suggest you to use the Low power and Timer server utilities. More details about that may be found on the AN5406 specially chapter 9.2 and 9.3.

Best Regards.
