Error Code 0xc2 ,, ret = NLME_NetworkDiscoveryRequest



I have a sleeping end device set to sleep mode after losing a network by using ZDApp_StopJoiningCycle() .

after wake up by user, it runs ZDApp_StartJoiningCycle().

The wired things is the end device never start to release a beacon to rejoin the network, but it is okay to send some zcl command out to the network (those network frame are correct too,...but other device cannot send command to this end device)

I have check that the devstate = DEV_NWK_DISC and devStartMode = MODE_REJOIN.

Also, i run the debugger and check out about ZDO_StartDevice(), i find the ret = 0x2c  after running       ret = NLME_NetworkDiscoveryRequest( zgDefaultChannelList, zgDefaultStartingScanDuration );
