Hi,

I am testing sample ligth application with sample light switch.

For sample light I am using SmartRF06EB + CC2538EM, for sample light switch i am using SmartRF06EB+CC2650EM.

I have problem to power CC2538EM using two AAA batteries. When I power on by 2 AAA batteries, EZ-Mode failed even though LCD and LED seemed to be working correctly.

When I changed power from batteries to USB power, every is working correctly.

Is it insufficient to use batteries for CC2538EM?

Thanks in adnvance.
