STM32WLE5JB doesnt exit from stop mode with LPTIM.

I've wrote a simple program only HAL used, the problem is same. Device doesn't wake up from stop mode.

#include "stm32wlxx_hal.h"
 
LPTIM_HandleTypeDef hlptim1;
 
void SystemClock_Config(void);
static void LPTIM_IRQHandler_Config();
static void MX_LPTIM1_Init(void);
static void GPIO_Output_Config(void);
void Error_Handler();
 
void LPTIM1_IRQHandler(void)
{
 HAL_LPTIM_IRQHandler(&hlptim1);
}
 
int main(void)
{
 HAL_Init();
 
 SystemClock_Config();
 
 LPTIM_IRQHandler_Config();
 
 MX_LPTIM1_Init();
 
 GPIO_Output_Config();
 
 while (1)
 {
 HAL_GPIO_WritePin(GPIOA, GPIO_PIN_2, GPIO_PIN_SET);
 HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFI);
 HAL_GPIO_WritePin(GPIOA, GPIO_PIN_2, GPIO_PIN_RESET);
 }
}

 {

 }
 
}

}

}

​The STM32WL Cube FW package is not officially available yet. It should be released by a month or two.

how you can make programme on this chip ? don't undestant .

in my side impossible to found Hal driver , i have buy some chip and made prototype , but impossible to programme :s

​You can't develop any application for now. You have to wait for the official release of the CubeWL FW pacakage.

A few companies have been delivered a beta version of the WL stack ahead of the official delivery date.

These lead customers help mature the stack, solving the last remaining issues based on real use cases.

The goal of this strategy is to improve the quality of the WL stack that is expected to be delivered very soon.

This should also prevent a sudden high level of support as soon as the whole WL ecosystem (Stack, CubeMX, CubeIDE, …) is released.

You can anyhow try to get the WL stack through the local ST FAE or sales covering your region. It is then a business decision.
