Current consumption during sleep

Hi,
I am using murata type-ZF design kit. I am trying to measure the current consumption during extended sleep mode which is supposed to be of the order of 5 to 10 micro amps max, but it is showing 120 to 150 micro Amps.
I am using smart snippets power profiler to measure the current, and The multiplier is set to 1x which was 10x before.
我的设置非常简单。我刚刚联系了board to my PC using the USB cable, and loading the firmware using smart snippets .
For just testing how much current it requires in sleep mode, I am using a code which just puts the board to sleep mode as soon as it is loaded. I have attached the zip file of the code. Apart from this, I also tried the sleep example in SDK 5.0.4, but that didn't seem to work well either.
I am programming the sram.

Can you please help me figure out why so much current is being consumed?

Hi krishnanag,

Hi krishnanag,

You are not able to measure the current consumption in the extended sleep mode using Smart Snippets studio. This tool is commonly used for power measurements, and can’t be used as an oscilloscope in order to measure mA. I highly suggest you to have a look at theTutorial 4 : configuring sleep mode on DA1458x.For downloading it, please visit our support portal websitehttps://support.dialog-semiconductor.com/and then enter to the “Connectivity: Bluetooth low energy & 802.15.4”. From the top menu bar click to the “Products”, then select the DA14580 SoC and go to the “Tutorials” tab. In this tab you are able to find all the available DA1458x trainings. Regarding the current consumption measurements in the murata boards, you have to use an amperemeter. Please check the link above, in which is described how you can do that.
