DA14585 doesn't wake up while external interrupt coming

Hi There,
I am using DA14585 with SDK 6.0.4.
My device connects to a acc sensor. Every 100ms, DA14585 will receive an external interrupt.
我也使交货tend sleep mode of DA14585.
I find that sometimes DA14585 will NOT wake up. Is it a bug?
Please check the image here:http://imgur.com/a/Zykxs
(I use a pin to show the status of DA14585. If the pin is high, it means DA14585 is not in sleep mode.)

I try to mark one line, "ext_wakeup_disable();", in the "arch_resume_from_sleep" function,
DA14585 will wake up normally on every interrupt coming. However, I am not sure the modification is feasible or not.
Could you please give me some suggestions?
Thanks a lot.

Hi,

Hi,

It is not cklear from your email, that you are using the wake-up timer, but this is your only option when you want to wake up using a GPIO. Please seehttps://support.dialog-semiconductor.com/system/files/restricted/UM-B-051_DA1458x_Software_Platform_Reference_1v2.pdffor details.

Now I understand clearly.

Now I understand clearly.
When DA14585 is sleeping and receiving an external interrupt. The function "ext_wakeup_cb" will be called.
After executing the function, DA14585 will go to sleep, so the callback function I set by using "GPIO_RegisterCallback" will not be executed sometimes.
My solution is to disable the sleep mode in "ext_wakeup_cb" function and restore sleep mode in "GPIO1_IRQ_Handler" function.
However, the console(UART2) and my external interrupts will use "arch_force_active_mode" to disable sleep mode.
The "arch_force_active_mode" function is NOT reliable!!! I think the function is only for console.
I totally modified the function.
Now, it works. I am really tired....Orz
