HI,

This behavior is observed even with other firmware! Looks like this particular board is damaged.

Thanks for your support.

Regards,

Hi,

Is the solder bridge from the SB9 cut properly? Does the kit function correctly i.e if you flash the blinky example from the SDK, does it work? What current do you measure if you flash the blinky example from the SDK on the board? What supply have you used earlier when you've tested the board? I'm suspecting that the board might be damaged.

regards

Jared

Hi,

Attached herewith the screenshots of the same.

All three cases I had cut the SB9 and used the power profiler. Could there be any damage while removing the short or other short? What else I could check?

Best Regards,

Viveknath

Hi,

I measured the current consumption with the PPK with a V2 and V1 board. As you see the result is similar.

V2:

V1:

Hi,

That's a lot in difference. You should get a similar result with the same FW. Could you upload your application as a hex? I would like to reproduce this myself. Are you using a softdevice?

You can find the HW files here.
