DA14531 sleep mode exit

嗨gowtham，

如果您尚未这样做，我建议审核以下文件：

http://lpccs-docs.dialog-semiconductor.com/Tutorial_SDK6/index.html

The first couple of chapters provide a high level explaination of the operation of the SDK and the associated callbacks, and give some details of sleep modes.

I'd also recommend the empty_peripheral_template as a starting point for any code you are going to write yourself (and this is the basis of the tutorial i mentioned above).

Hi tsgowtham,

我假设，当您使用Power Profiler时，您在DA14531的控制下运行代码在调试器的控制下。这没问题，但是一旦开始运行的代码，需要通过按“Ctrl + F5”断开调试器，否则调试器仍然有效并绘制当前。

Hi tsgowtham,

Please refer to my answer to your questions below：

• From the tutorial link you have given, I understood that for waking from Extended sleep, the code performs a periph_init and continues execution. But what is done for the other sleep modes?? This has not been mentioned.
• [ycai]其他睡眠模式,而延长leep mode, there will be one more reboot process. Reboot process will re-copy the firmware data from external storage into RAM. The above process has been implemented by the SDK. The above process has been implemented by the SDK. From the perspective of the user, no matter which sleep mode is woken up from, the program will first run to a callback function in the user layer. The callback function may be called by RTC, GPIO, TIMER1 and so on.
• My application is to read a sensor value using I2C every 20ms and transmit the data to a connected phone. I would like the DA14531 to be in sleep for the rest of the time. Would it be possible to use Hibernation mode or deep sleep in this scenario?
• [ycai] The answer is yes. However, I suggest to use extend sleep mode, because another sleep mode requires an additional reboot process, which will also consume some power.
  When the sleep interval is long enough (such as 2s), the two external sleep modes are meaningful

I am having the same problem. I started with DA14531-DA14585-586_Service_Data_Beacon which sets
app_default_sleep_mode = ARCH_EXT_SLEEP_ON;
但未修改示例中的广告之间的电流约为1.7mA。更改为Arch_sleep_off将电流增加到1.9ma。

This is with using the SmartBond Flash Programmer and cycling power to the Dev Kit before making the measurements.

我下载了Prox_reporter（由SDK Source建造，预先构建的“下载在线固件”版本来自SmartBond闪存程序员），并且如要求测量的峰值和平均电流都是0.00000 mA。图表是底部的直线（见附加PDF）。

I verifed with BLE Scanner that the DLG-PROXR device was advertizing every 689ms.

I also tried the pre-built ble_app_barebone_531.out.bin from the online resources. The current looked more normal with an average of 0.16758 mA and peak of 3.181 mA.

Please let me know if I should move this discussion to a different thread. It appears to be the same problem, but I do not want to hijack the thread.

嗨乔恩，

所以w / o spi flash问题你面临着prox_reporter的“零电流消耗”的一个问题？你能确认宜宾建议的步骤吗？

0.在531开发套件上拔下所有跳线

1.将SDK的Prox_Reporter项目的固件下载到531 Dev-kit上的Flash

2. Unplug and reinsert the USB cable

3.打开SS工具箱 - >选择UART / SPI接口 - >打开Power-Profile工具

Hi tsgowtham,

Could you please take a look at the Sleep mode tutorial from our support website? Link is provided below.

谢谢，PM_DIALOG.

Hi tsgowtham,

In the Sleep mode tutorial, the tables with extended sleep mode currents are for the DA14531. In your initial post, the DA14531 module is tagged. Please refer to the module’s datasheet and see Table 4: DC Characteristics.

您提到平均电流消耗量为0.02 mA。您使用的广告间隔是什么？这里，该设备是广告的，并且在广告间隔之间进入扩展睡眠模式，并且它将通过BLE定时器自动唤醒。

如果遵循睡眠模式教程，您将看到广告时期之后，芯片将停止广告并进入永久睡眠模式（没有BLE Activity）。何时何地是永久睡眠模式下的电流消耗？

此外，您能否注明您使用的项目？如果你能与我分享它，那么在我身边运行它也会有所帮助。

谢谢，PM_DIALOG.

Hi tsgowtham,

extup_peripheral_template不会停止广告，因此设备在广告或连接间隔之间睡眠。Prox_Reporter正在使用超时的广告，因此该系统不仅进入睡眠模式，不仅在广告或连接间隔之间进行睡眠模式，一旦广告停止，总线就会进入永久睡眠模式。但是，Prox_Reporter正在使用SPI闪光灯，从而减少功耗，您需要将其供电，并在设备唤醒后释放它。

谢谢，PM_DIALOG.

Hi tsgowtham,

Glad that you are able to reduce the power consumption and thanks for accepting my answer. Thanks for your feedback too!
