How to wake up DA14580 device

Hello Asmaitha, have you read the apps note on how to configure sleep mode either synchronously (BLE Timer) or asynchronously (interrupt) ?

http://support.dialog-semiconductor.com/um-b-006-user-manual-sleep-mode-configuration

This is quite a comprehensive apps note, and is the best place to start.

Hello JE_Dialog,

I'd wonder how to identify the wake up events,such as two short pulse to wake up the system asynchronous.Thank you!

Hi young_dialog,

我不让你的问题,请澄清吗?You can use the wakeup controller and set it up using multiple pins, if that is what you mean.

Thanks MT_dialog

Hi young_dialog,

Yes thats right, you can declare many wakeup pins, but you have only one callback, if you want to identify from which pin you got the interrupt you can try to read the status of the pin after getting the interrupt and check which of your pins are high or low.

Thanks MT_dialog

Hi young_dialog,

There is no other way doing this, you can either read your pins or you can try to set the GPIO IRQs for the connected pins if the sources connected matches the available IRQs. You dont have to do anything explictly in order for the 580 to retain the state of the pins, when it falls to sleep, while you are in sleep mode the state will be retained, but you will have to keep the state of your pins since when the 580 wakes up, the periph_init() will run and your pins are going to be reconfigured.

Thanks MT_dialog

Hi MT_dialog,

I try to use the GPIO IRQs to wake up the system periodically and it work well on active mode and doesn't work on extended sleep mode.By the way,the interrupt is triggered by the pulse

generating from the ADC chip with period of 4ms.Is it too short to wake up the system?Any suggestion?

Thank you!

Hi MT_dialog,

As we know,DA14580 can wake up by Wakeup Timer and Quadrature Decoder when in Extended or Deep sleep mode. I wonder how to wake up when only GPIO IRQs is used?Thank you!

Hi young_dialog,

I dont think that 4ms is too short to wake up the system and trigger the interrupt, have you try to properly configure the debouncing parameter on the wakeup setting and at the GPIO IRQ ? Cause i tried with a 4ms pulse and i could wakeup the system and trigger the IRQ.

Regarding the waking up, you can't wake up the system via GPIO IRQs only the wakeup timer and the Quadrature can wake it up.

Thanks MT_dialog

Hi young_dialog,

You can use the following functions when you want to switch between the sleep modes:

arch_disable_sleep() : the device will be active

arch_set_extended_sleep(): the device will swicth to extended sleep mode

You can invoke the above functions when connected and disconnected from the central device by invoking (arch_disable_sleep in the user_app_connection callback and arch_set_extended_sleep in the user_app_disconnect) its the same with the arch_set_sleep_mode() with the proper parameter. In order to start advertising again after disconnection you will have to invoke arch_set_extended_sleep() and user_app_adv_start() in the user_app_disconnect in order to set the device in exteded sleep and start advertising again.

Also please dont post a different question under the same thread, you can always create a new thread.

Thanks MT_dialog
