Posted on September 05, 2017 at 12:15Hello ,
i'm using murata's module CMWX1ZZabz including stm32l0, with the provided lorawan_cube code , here is the lowpower_handler fontion, anyone has an idea how to control the MCU wakeup.
in addition to that, the consumption is high in sleep_mode : 1.5mA instead of ~5uA .
Thank you
void LowPower_Handler( void )
{
DBG_GPIO_RST(GPIOB, GPIO_PIN_15);
DBG_GPIO_RST(GPIOB, GPIO_PIN_14);
if ( LowPower_State == 0 )
{
HW_EnterStopMode( );
/* mcu dependent. to be implemented by user*/
HW_ExitStopMode();
DBG_GPIO_SET(GPIOB, GPIO_PIN_15);
HW_RTC_setMcuWakeUpTime( );
}
else
{
DBG_PRINTF_CRITICAL('z\n\r');
HW_EnterSleepMode( );
DBG_GPIO_SET(GPIOB, GPIO_PIN_14);
}
}
