Power Consumption Measurements and Optimization for
CC2538 End Device With Z-Stack
SuyashJain
ABSTRACT
This application report describes how to set up power consumption measurements for a CC2538EM (end-
device) node running Z-Stack™. The application used for these measurements is the Z-Stack Home
sample light and sample switch application, included in the Z-Stack-Home release (downloaded from [3]
and it is described in [4]). This document uses the ZigBee PRO stack profile.
