Please let me know how the operation of the sample application cc2530zdk

um..thank  you 

but, I mean sw1 & sw2 operation in the sample application..

please, help me

What same application do you test? If you use examples in  Z-Stack Home 1.2.1, it should be no problem using SW1 and SW2.

i use a sample application for cc2530(cc2530zdk).

and my problem is do not work properly..

Below is a description of SW1,SW2(In Zstack Sample Application for cc2530DB)

SW1: Sends a flash message to all devices in group 1.

SW2: Toggles the device’s enrollment in and out of group 1.

thank you

I never heard that TI's examples use "SW1: Sends a flash message to all devices in group " and "SW2: Toggles the device’s enrollment in and out of group 1." Does your example provided by TI?

Sorry, I see it in Z-Stack 2.5.1a sample application now. So, do you setup a coordinator and make a device to join coordinator first?

Document name is Zstack Sample application for CC2530DB, Document number is SWRA232

and i solve the problem 

thank you :)

Good to hear that you solve the problem. Could you share how you solve it to benefit others have the same issue?
