sleep mode of cc2530

It is inside InitBoard().

hi sir ,

is there any examples for implementing sleep mode in Z-Stack Home 1.2.1

Every ZED examples in Z-Stack Home 1.2.1 implement sleep mode. When you enable POWER_SAVING and NWK_AUTO_POLL in compile option, ZED would go to sleep mode automatically.

in sample switch(ZED)  and sample light(ZC) ... how to visualize sleep mode in the ZED sir   

You can connect a current meter to your ZED battery and watch the current consumption. If ZED goes to sleep mode, the current consumption must be below 1mA.

but sir even the led in the ZED is remaining glowing in the power saving mode ... is it possible??

No. If your LED remains glowing in the power saving mode, it will cost more.

yes sir .. . i set the power saving mode the led is still glowing sir ?? 

Do you modify anything in function halSleep() of hal_sleep.c?

no sir .. i didnt 

Does your application control LED to on or off?
