I was able to use your "Deep Sleep Configuration" example to and successfully set up to wake from Timer1. Using the Power Profiler I see that my average current consumption is around 40uA.
I would like to achieve even lower average current consumption using the same setup, but perhaps modulating the Timer1 time to wakeup. Looks like it might currently be waking up every 700msec.

我使用DA145xx Pro Development Kit 测试DA14531的功耗，
使用的程序是官网下载的Simple Beacon Example例程
测试的平均电流为1.85mA
这个例程怎么比网上图片上显示的电流大很多，
这个是正常的吗？如何降低平均电流
测量结果见附件

I am configuring the rtc module for timing function,
rtc_clk_config(RTC_DIV_DENOM_1024,32768);
I want to know what is the difference between RTC_DIV_DENOM_1024 and RTC_DIV_DENOM_1000, which configuration is more accurate?
thanks！
Hello,
I am connecting a RGB led to DA14531 and I have been looking for the maxmum output ratings in the datasheet with no luck.
In the dev-kit a 180 ohm resistor used. At 3 V this will be around 18 mA.
What is the limit for each gpio pin and it there a total limit?
Hello there,
Is there a way to detect a previously paired device?
I'm using thescan_request trackerexample andble_app_securityand I'm able to print out the address of the device that has sent the scan request. However, I want to check this address and know when a device that has been paired and is disconnected, sends a scan request.
Is there a way to verify if a device has been previously paired with?
Regards,
Hamid
Hi Dialog
我下载了SmartBond_PLT_v_4.4.2量产工具压缩包，解压缩后双击SmartBond_CFG_PLT.exe之后弹出：
failed to convert system string to char erro： cfg_gui_comon.cpp，是不是还需要安装其他软件。
As far as I understood, in deep sleep mode it is possible to also power off the SysRAM to save more power and then program the SoC so that the OTP (One-Time Programmable) is instructed to automatically get mirrored into RAM upon every wake up.
Although more power efficient especially for long advertising intervals, I was wondering what would be the effect in the long run of having the application being mirrored again and again into RAM at every wakeup.
Is there a guaranteed number of read/write operations for the SysRAM?
Thanks
Hello Dialog,
I'm using a DA14531-00FXDEVKT-1 to connect the PC terminal to SmartConsole Android App. Firmware on the dev board is Codeless Standalone Set-One.
I can send a string from the PC terminal to SmartConsole using pipe char. But can't send AT commands to control the module.
从SmartConsole,使用“+打印= sometext”我get response "OK" but nothing reaches the PC terminal.
Best regards
Filipe
Hello,
I think I might have bricked my DA14531 USB DevKit by flashing inappropriately modified SW onto it.
Now, when I try Connectiong through SmartSnippets Toolbox (v5.0.14) it prints the following:
[INFO General @20-10-18 10:30:46] Could not measure total IR len. TDO is constant high.
[ERROR General @20-10-18 10:30:46] No known chip found while opening JLink connection. Terminating proccess...
[ERROR SPI Flash @20-10-18 10:30:46] Failed downloading firmware file to the board.
Hi, Dialog
I've read some code about DA14531, I do not know much about this device.
I wouder if DA14531essay writercan be connected with multiple central devices at the sametime?
和中央设备可以支持多少?
Thanks.
