Hi again Amanda.
Regarding consumption, it seems the problem was with this particular model, probably damaged during testing. Thanks anyway.

Update: I tried with a new dongle and the huge absorbing is gone.
Back to a "normal" 0-5 - 1.5 mA
The strange things are:
with a two news dongle one absorb 0.2m the other 1.2 mA.
Same firmware (of course!).

There is something I must know?

Hallo Amanda.
Struggling with the modifies of the "original" Peripheral LBS example.

I used "as is, w/o mods, but the pow consumption is still huge (27 mA ).

How I can handle it? Try with removing
CONFIG_NCS_SAMPLES_DEFAULTS=n
but none.
No way to remove printk form compile, so also the USB and serial debug is still running.

I'm in panic, please help me, thanks in advance.

Thanks Amanda, now it works.

It seems that the program exeed the flash memory area, so the 'pm_static.yml' file adjust it.
I haven't found the mentioned post, sorry.
Anyhow, I got similar problem using the example Peripheral UART: Adding the .yml or not I got all the led ON an the board.
Could you check if it's similar things or need to open other topic?

Thanks again,
