I saw the following thread, but I couldn't wake BCM20737S up from DEEP SLEEP mode.
How can I make bcm20732s sleep and wake it up by GPIO interrupt?
Are there any mistakes in my code? Please tell me what to do.
I imitated the code of i2c_temperature_sensor sample and added following code in create function.
**************************************************************************************************************************************************
{
devlpm_init();
devlpm_enableWakeFrom(DEV_LPM_WAKE_SOURCE_GPIO);
gpio_registerForInterrupt(interrupt_handler_mask, abc_gpio_interrupt_handler, NULL);
gpio_configurePin(GPIO_DS_INT_PIN/16, GPIO_DS_INT_PIN%16, GPIO_EN_INT_RISING_EDGE | GPIO_PULL_DOWN, GPIO_PIN_OUTPUT_LOW);
}
**************************************************************************************************************************************************
Then, I implemented abc_gpio_interrupt_hndler function.I want BCM20737S to advertise again just like before it enters deep sleep mode when GPIO_DS_INT_PIN(P4) rises up.
**************************************************************************************************************************************************
void abc_gpio_interrupt_handler(void* parameter, UINT8 arg)
{
ble_trace0("Wake up!\n");
gpio_clearPinInterruptStatus(GPIO_DS_INT_PIN/16, GPIO_DS_INT_PIN%16);
// If disconnection was caused by the peer, start low advertisements
bleprofile_Discoverable(HIGH_UNDIRECTED_DISCOVERABLE, NULL);
}
