OK,got it. I will do it.thanks Msromero.

Do you have many sensors and other devices that also draw current on your PCB? Perhaps it's not only the nRF chip drawing current. If you want your whole schematic reviewed you can create a private ticket and share your files with us.

Dears,

Because we use system_on_sleep_nrf52832.hex ,this image could get almost the same result.

about 14mA current.so we guest HW issue.also,this new design HW changed, bring a LDO ,power to sensor.

thanks.

Hi,

Depends. What were your measurements when you tested system_on_sleep_nrf52832.hex? Are you suspecting any particular HW issue? Why are you suspecting that? Have you tried to test system_on_sleep_nrf52832.hex on multiple boards or just the one? Are the measurements the same?

BR,

Marjeris

Dears,

Thanks for kindly support.

After using your image, we found it should HW issue. About that, is there any suggestion?

Thanks.

A couple more of suggestions:

What kind of software or software example from the nRF5 SDK are you running on the chip?

And can you test using this file and measure the current consumption then?
devzone.nordicsemi.com/.../system_5F00_on_5F00_sleep_5F00_nrf52832.hex

You also need to check if you multimeter/current meter has the capacity to measure the average current accurately, we recommend using the PPK2 for measuring power consumption on our chips:

For average current 14mA sounds a bit high. Are you using any other peripherals in your design using the same supply circuit?

Is there any suggestion for this case? Thanks a lot.

Thanks for your supporting.

It is average current. method is adding current meter to supply circuit.protocol stack is S132 7.0.1.

Hi,

Are 14mA peak or average current? How are you measuring it? What firmware are you running on the nRF52832?
