Hi Simon,

Thank you so much. You were 100% correct. After adding CONFIG_SERIAL=n to the prj.conf file the current dropped right down to 186uA. Really appreciate the help. You restored my faith in the new SDK. :-)

Kind Regards

Julian

Hi Simon,

Thank you for getting back to me on this so quickly. That is a good point, I will give it a try and then I will loop back my findings.

Kind Regards

Julian

Hi Julian

My guess is that logging is turned on in your NCS application (as they are in most samples by default). The current consumption should be very similar to what you see in the nRF5 SDK for most sample applications (it is enabled to simplify development). You can try turning off all serial communication by adding CONFIG_SERIAL=n to the prj.conf file.

Best regards,

Simon
