Configuring network using z stack energy 1.1.0 sample program

Other Parts Discussed in Thread: MSP430F5438, CC2520

Hi,

I am working on Z stack energy 1.1.0 sample application Hardware being used is MSP430F5438 experimenter board along with CC2520 transceiver.

I want to send the data using multi-hopping. I want to know the mechanism behind the association of end device with the parent device (router/coordinator). Whenever I try to associate the end device to the network sometimes it gets associated to zigbee coordinator and sometimes to a router. The process gets more complicated whenever there are more than one router devices and end device is to be associated to its parent.

Is there some document where I can find the details regarding this mechanism? And how can I control this behavior in the code.


Thanks and regards

Yuvraj

    Before ZED start association, it will broadcast beacon request and wait ZC/ZR to response. If All of your ZC/ZR allow association, ZED will pick one with best signal strength. If you want to make ZED associated with specific ZR or ZC, you have to use ZDP_MgmtPermitJoinReq() to only allow permit join on specific ZR or ZC.
