Hi
1.
我在DA14580子板中使用的Proximity报道器被修改为升压模式。当前波形是在智能片段的电源分布器工具中获得的。从广告开始时，在每个广告事件之间睡眠期间，睡眠期间有一些加速电流并持续两个秒。此后，广告与它们之间的一些1.4 UA的睡眠电流正常。为什么具体的2秒是这样的升级电流？

while the daugther board is working on 0.9 or 1 volt it is consuming much current than other supply voltages ! why it is so ??
3.
How to use the smart snippet to measure the current by providing external supply to the daughterboard(not via mother board).
嗨Hrq，
1) Sorry, I don't see the increased current between the advertising events, during the advertising events which last about 4 msec, the base current is about 1mA, the Rx/Tx peaks are about 10mA.
整个广告活动持续约11个SMEC，之后该设备进入睡眠模式并消耗约1.5μA。
Only in the begiining of the advertising event, I see a current of about 1mA during 2 msec, after which a short dip (1msec) occurs, 3-4 msec later first advertising occurs.
2) the consumed power is the same for boost or buck mode.
To compensate for the lower voltage, the DCDC converterer draws more current from the battery/supply.
3) for this, you can remove jumper J13, and connect a supply to pin j13/3 (middle right hand pin of J13.)
By doing so, the current is still forced to flow through the current measurement resistor R11.

谢谢你bb_dialog .i用2）＆3了。但是reg 1）我无法获得你解释的东西。
From the first advertising event for a period of 2 secs the sleep current is 1.1 to 1.7 mA (peaks), after that a short dip happens and now the advertising is normal with sleep current of 1.2uA.So why high sleep current is there for first 2 sec ?
（注意：如果在论坛上有透明度来上传波形图像以清楚地了解，则会很棒）
嗨Hrq，
I agree with you that adding some screenshots would be very handy! The 'add media' button is already present, but doesn't seem to work yet.
Sorry, now I understand the thing you see: the first 2 sec the device has higher activity. This only happens the first time after a cold boot.
出现出睡眠模式时，它不会发生。
这是你所指的吗？

Hi BB_Dialog
不，即使在深度睡眠模式后，当我按下按钮K1相同的现象发生了2秒，而Den恢复正常!!
Hello,
I am trying to measure the current in DA14580, I try with the reporter_fh project but I receive any answer in Smartsnippets(v3.3). Is right with this project, or I must do with other?
谢谢
Helllo DesignExt, there are seveal methods for measuring current. Smart snippets can measure the active currents where you can see the current consumption in different modes (active/sleep modes, tx and rx) when you use the EXPERT development kit (motherboard / daugtherboard).
Noet that to accurately measure sleep/extended/deep sleep currents, since it can be
Please read following document to describe all this .

嗨Hrq，
I tried to reproduce your observations, but I can't.
按下按钮（K1，K2）时，我会看到持续时间的增加的电流我按下键。电流级别= 0.055 mA。
最佳reogds，bb_dialog，对话框支持团队。
Thankyou .
1）我用另一个女儿板加载到SRAM。唤醒唤醒没有2秒的活动。因此，如果我完全关闭并在特定时间后再次重启它，每次都会发生2秒的高电流？
2) could you explain what happens in that 2 sec duration causing it for high current acitivity during coldboot.
3) Is there any way to overcome or reduce this high current.because we need to restart the ble after some period and this high current will cause some additional power consumption .!
Hello hrq,
yes, this 2 seconds of increased activity and higher current always occurs when executing a cold boot. This can't be avoided.
This doesn't happen when coming from extended or deep sleep.
Is it not possible for you to use the sleep mode instead of switching off the chip completely?
I'll check with development what exactly happens during these 2 seconds.
One event that happens directly after the cold boot is a RF-calibration, but this happens during the first 10 milli-seconds.
This calibration is then directly followed by the first advertising event.
最好的问候，bb_dialog。
嗨Hrq，
更新：
我刚才了解到了为什么这种增加的电流发生以及如何减少。
它是由32 kHz Xtal振荡器引起的，需要大约2秒的沉降。
The system is not alowed to go into sleep mode during these 2 seconds.
When using the RCX oscillator (no 32KHz xtal required), the time is considerably shorter:
I measured some 30 milli-seconds, including calibration and first advertisement.
二手充电约为42微水库。
在我们的SDK中，调整以下行：
#define cfg_lp_clk在da14580_config.h中
0x00 = 32KHz Xtal ; 0xAA = RCX oscillator.
Please note that RCX oscillator can only be used in Buck-mode, not in Boost-mode.
Best regards, BB_Dialog
Thankyou BB_dialog for the useful info. The 2 seconds settling time for the 32Khz Osc is software delay provided in the code or its the time taken by the osc itself to stabilise??
嗨Hrq，
在软件中设置了2秒，但是32kHz水晶Ocillator需要进行沉降。
更加积极re going into sleep, it must be sure the ocilaltor has settled to the right frequency.
Slow KHz clocks require more time for this than fast MHz clocks.
We are studying whether this settle time could be made shorter.
No planning available.
最好的问候，bb_dialog。
