CC2530: Communication handshaking between CC2530 End device (Zstack 2.5.1) and Wireless sensor/Wall switch (HA1.2)

Part Number:CC2530

Hi,

Actually, I am using CC2530 as a End device to develop some LED driver products.(i.e., I use Zstack 2.5.1 to develop, NOT using HA1.2). But I plan to buy some 3rd party Zigbee Sensors/Wall switch products, which use Zigbee HA1.2. So, can I do handshaking between our developed CC2530 enddevice and these Sensors/wallswitch? (i.e., is it possible to do data handshaking: one sided is Zstack 2.5.1, another side is HA1.2). If so, is there any important issue I have to take care?

Thank you very much
