zigbee routers destroys zigbee network

Other Parts Discussed in Thread: CC2430

Hi,

We are trying to construct Zigbee network with couple of routers and end-devices( 1 coordinator, 4 routers, 80 end-devices, MAX_children=20). We are using cc2430 chips and zigbee stack 2007( not Texas). The first step what we are doing is connecting routers to coordinator and then starting to connect end-devices to coordinator and routers, then at some point network fails and it seems that routers are causing the problem(there is no problem with 1 coordinator and 20 end-devices network). When this happens coordinator doesn't have network anymore and it can't do new one on the same channel before all routers are switched off. 

I don't understand why this is happening and I can't find any information in the Zigbee protocol how router could kill the network.

I appreciate all the comments regarding this issue.

    Hi,

     

    I am not an expert on this but can let you know of a probabilty which you need to test.

    1. When you go on increasing your network, your coordinator is unable to support the depth and maybe due to some stack overflow issue it could be restarting.

    2. Since routers are present they would be transmitting beacons, which is detected by the coordinator when it restarts and hence it will not try to create the same network.

    You need to check the following.

    1. If your coordinator is restarting the network due to any overflow issue.
    2. On restart your coordinator should have NV Restore option to continue opertaing on the previously set network parameters.

    Hope the above helps
