Part Number: CC1352P
Other Parts Discussed in Thread: ENERGYTRACE

Tool/software: Code Composer Studio

Our CC1352P based custom PCB can be configured as Transmitter / Receiver / RF disabled.

When RF disabled, EasyLink API not used, including EasyLink_init() not invoked during initialization.

Noticed power consumption increased by ~150-200uA when EasyLink_init() is not invoked during startup.

Hi Amit,

I've assigned your post to an expert to help you with your question.

Do you have our LPs so that you can do the same test there and compare the results? 150-200 uA indicates that an IO is drawing current.

Hi,

Not sure how to measure LP current consumption as it is powered by USB.

As workaround, invoked EasyLink_init() during startup.

you can mesure current consumption on the LP using EnergyTrace:
