DA14585 doesn't wake up while external interrupt coming

Tue, 2017-09-05 11:51 -- stanley_yeh

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.
I also enable the extend sleep mode of DA14585.
I find that sometimes DA14585 will NOT wake up. Is it a bug?

(I use a pin to show the status of DA14585. If the pin is high, it means DA14585 is not in sleep mode.)

How to implement RTC in very low power consumption?

Sun, 2017-09-03 04:22 -- brent_zheng

Dear Sir,
In my project, device was using very short time, maybe 2min per day. But I need keep RTC counter, to record the time user use device but no turn on BLE. It current SDK, I need set device to work in ext sleep mode, and setup app_easy_timer, the current is about 3uA, it's too high. If I set device to work in deep sleep, can I use timer to period wakeup? If yes, because wakeup from deep sleep will cause system reset, how to know the reset reason? How to keep counter variable?

Best regards,
Brent Zheng

Can I do not turn periph off during ext sleep, so that timer0 can work

Hi, Dialog
In my project, I need measure the time between GPIO interrupt HIGH to LOW and LOW to HIGH, the time is very short sometimes, like 0.1ms. So I can not use tick. To save power consumption, I want device stay in ext sleep, timer0 working in background and set GPIO to wake. Once GPIO interrupt trigger, I will read the timer0 count and record it.
Now the problem is timer0 was off during ext sleep by default. Can I set system to extsleep, but keep timer0 power on?

Best regards,
Brent Zheng

Using BT HCI over UART for DA14585

Fri, 2017-09-01 13:19 -- rahult


We would like to know how to enable BT HCI over UART mode of DA14585. Are there any settings that need to be done ? We want to send the BT HCI command over UART directly to BLE controller and get back the response back. We want to use another Bluetooth stack and communicate with chip directly.


Problem of porting ANCS to DA14585_SDK_6.0.4

Fri, 2017-08-11 16:11 -- lizhuobin

Dear Dialog,

I get DA14585_SDK6.0.2_ANCS_Client.

I porting ANCS to DA14585_SDK_6.0.4.

When the phone connect to the device, the system reset.

Here is the reset log,
