Hi
I have just bought the X-NUCLEO-LPM01A for power current measurement.
It supplies 1.8 to 3.3v as a power supply and provides a measure of the current draw down to a resolution of 100nA.

Is there a convenient place that I can attach the NUCLEO power supply so that it only supplies the 14695 + flash chi so that I can measure the current it is consuming and does not include the current for all the other chips on the board like the segger chip.

Look forward to hearing from you.

Thank you in advance.

Hi there,

I am using proxy_reporter and iOS app to measure current using with DA14583 / Pro kit. But always have 0.5mA ish static current in Smartsnippets measuring while the dynamic behavior looks OK (Tx/Rx waveform good). iOS app maintains good connection. Please see attached current measurement plot.

Changes from out-of-box SDK 5.0.3 (above drop down menu only allows me to choose 5.0.2.1 the highest version).
1. HW_CONFIG => 2 (pro kit)
2. select prox_reporter_583 in Keil (5)

I'm using the default jumper settings on the Pro kit from the factory. I have no JTAG attached - just the mini USB cable for Smartsnippets.

I've tried to calibration offset - which is only 0.018mA - no help in my case.

Tried Keil debug run, Smartsnippets booter serial download, burn SPI flash, same result.

I've read all the topics searched with keywords "current measurement" in the forum, tried the stuff mentioned, still bad.

I'm using DA14583 + Pro, is it of any difference from DA14580 in terms of jumper setting etc?

Does anyone have any more hint?

I'm wondering if the chip does not go to sleep in my case given the current 0.50mA is very much similar to active running mode. If I want to debug that, what's the best way to do it?

Further note: I'm trying to debug if the chip goes to sleep - http://support.dialog-semiconductor.com/ble-app-uart-debug-messages - after the change the prox-reporter does not advertise.

Any feedback is welcome.

Cheers,
Carl
