Forum Post: what is this payload

Hi All,

I am using ZStack-CC2530-2.3.1-1.4.0. I want to implement security in my network. as suggested in "z-stack developers guide", i built my coordinator and router code with the preprocessor flag SECURE set equal to 1. also i used the default key in file f8wConfig.cfg. and made zgPreConfigKeys = FALSE in file ZGlobals.c

I started the coordinator. then i started the router. i saw the packet exchanges between  them using sniffer.

When i am not using security, after joining the coordinator, the router sends a device announce packet.

when i enabled security, i saw in the sniffer, that router joined the network and coordinator send a packet containing the IEEE addresses of both router and coordinator and also the default key to the router. Next i saw 2 packets being broadcasted. I want to know what are they. Are they device announce in encrypted form? If not what are they?

I am attaching the data captured from sniffer. coordinator IEEE address is : 0x00124B000148D136

router IEEE address is : 0x1124B00014A1AB4
