DA14681 sleep and wakeup timer mode?

Wed, 2020-09-23 10:48 -- mahmed106

Hi dialog

I m working on custom baord based on DA14681. I want to know how to go into sleep mode and how to set a synchronous timer to wakeup automatically.

Actually my application needs that device automatically wakesup after every minute, read ADC temperature, writes to flash and go back to sleep. I want to know is there any example code where this kind of sleep is implemented. Or if you can help me for this?

Secondly device must also be availble for SUOTA update or BLE data transfer. Please tell how that can be managed while sleeping?

Wakeup Dead batteries via DA14681

HI dialog

We are working on two custom boards based on DA14681. One has external charging ic "MP26029" and other is using DA14681's internal charging setup.

The problem which we are facing is that when customer dont use the device for a long time, battery's voltage drop too much. sometime it goes to 0.8V or 0.6V.

Then when we plug in the charger, DA14681's charger is not able to charge the battery, even after 24 hours of plug in the charger, but other board that has external charging IC, that charges the battery within 4 5 hours.

Current Spikes when in Extended Sleep

Thu, 2020-09-17 20:21 -- Merigh

Hello,

I have a custom PCB with Dialog 14682. I am running into an issue where, when I enter extended sleep, the CPU appears to wakeup momentarily every 2 or 3 milliseconds. I am using an accurate DMM to see that the sleep current does drop to ~6uA, and that the spikes are in the 1s of mA, so not high enough that the radio is turning on, but rather indicating the CPU is waking up, possibly. This means that my average sleep current is something like ~200uA instead of ~6uA.

DA14683芯片不工作

hi,Dialog

最近我们试产了一批5000pcs的产品,其中有20pcs可以烧录成功但是上电后不启动不工作,其他产品都是ok的,经过我们测试发现外部电路是没有问题,是DA14683本身的问题,所以我们想知道造成这种现象一般是由于什么原因造成的 ?有没有其他客户反映过此类问题?

谢谢

DA14681 issue with SUOTA update when timer0 set at 20Khz?

Sat, 2020-09-05 08:52 -- LennoxConner

I m working on a custom board based on DA14681 and recently i came to an issue that suota update stucks when i set timer0 at 20Khz.  At 1Khz timer0, suota update works fine.

When i debug this issue, debugger omegle xender halts at a random location everytime. Dont know what is the problem?

Is there a work-around for this?
