Hi there,
I am using the smart snippets power profiler according to the documents Training_04 to measure the current consumption of the Da14580 board during extended sleep modes. However, my power profiler did not come out with any values. I have do accordingly to the training document. I hope that you could help. Thanks!

https://support.dialog-semiconductor.com/power-profiler-basic-dk. Is this link true? saying that there is no profiler function for DA14580 basic?
Hi herochua617,
Yes its true, as the below FAQ, on the bottom of the web page.

Thanks!
Hi, Dialog
I have read the AN-B-023 (DA14580 interfacing with external memory) document about the booting time current consumption. And I also see the discussion topic (https://support.dialog-semiconductor.com/addtional-current-during-power#...) saying that 32KHz Xtal oscillator need about 2 seconds to be stable.
I would like to ask that the current measurement in AN-B-023 contain the 2 seconds stable current? Thanks.
Hi Liang Yun Hao,
The current measurement only includes the power consumption of the booting sequence from an external device, the device stays awake for the XTAL32K to stabilize while the device is active and running your firmware, the power consumption of the device in that case it depends on how often you are advertising, it just doens't go to sleep. The current measurement on the document that you mention doesn't include the time that the 580 stays awake for the XTAL since this consumption is application dependant.
Thanks MT_dialog
OK. Thanks for your reply.
Hi MT,
I have one query on power consumption as below:
- If i have two device with all same configuration except one is with connectable advertising interval @100msec and other is in connection with 100msec connection interval. Which one will consume more power?
- While SoC(Da14583) is in connection established state with connection interval @100msec, Does the SoC goes in sleep mode inbetween this 100msec?
- As we have query, which should be more power optimized solution, An connection less(advertising interval) or connection established (connection interval)?
Hi Bismalsinh,
- Well, if there is no activity on the BLE on the connected device, so the device transmits and receives only empty packets then the connected device will consume less that the connected with the same interval, in the advertising event the peripheral advertises and scans in all three advertising channels, while in connected mode the device transmits and receives in only one channels.
- Yes the 583 as the 580 goes into sleep between the advertising and the connection intervals.
- There is no clear answer on this, since that depends on multiple factors, connection interval, advertising interval, how many data should be passed over BLE, etc and the application off course.
