hello,
i am using bluenrg 1,and i write code for remote control application.
Issues- I called a function to sleep bluenrg1 in main.c , and i used gpio12 and virtual timer to wake-up the device.But device is not wake-up when i put gpio12 at low unless resetting the device.Also virtual timer unable to wake-up the device at definite timeout .
so help me out how to do whenever gpio12 at low and without resetting the device. System should wake-up as well as by virtual timer to wake up the system whenever the 2 sec. timeout occurs.
Here i am sharing how i configure the sleep mode.
In main.c
/* Enable the Sleep - SLEEPMODE_WAKETIMER */
void sleep_timer(void)
{
uint8_t ret;
wakeup_source = WAKEUP_IO12;
wakeup_level = (WAKEUP_IOx_LOW << WAKEUP_IO12_SHIFT_MASK);
printf("\r\nEnter to Sleep - SLEEPMODE_WAKETIMER\r\n");
ret = HAL_VTimerStart_ms(0,2000);
if (ret != BLE_STATUS_SUCCESS) {
printf("HAL_VTimerStart_ms() error 0x%02x\r\n", ret);
while(1);
}
BTLE_StackTick();
ret = BlueNRG_Sleep(SLEEPMODE_WAKETIMER, wakeup_source, wakeup_level);
if (ret != BLE_STATUS_SUCCESS) {
printf("BlueNRG_Sleep() error 0x%02x\r\n", ret);
while(1);
}
/* Stop VTimer */
HAL_VTimer_Stop(0);
}
/* Infinite loop */
while(1)
{
/* BlueNRG-1 stack tick */
BTLE_StackTick();
/* Application Tick */
APP_Tick();
/* Enable Power Save according the Advertising Interval */
sleep_timer();
}
And in BlueNrg1_it.c
void GPIO_Handler(void)
{
if((GPIO_GetITPendingBit(GPIO_Pin_12) == SET) || ((wakeupFromSleepFlag) && (BlueNRG_WakeupSource() == WAKEUP_IO12)))
{
GPIO_ClearITPendingBit(GPIO_Pin_12);
}
}
