What is the max device number in one ZigBee network when using CC2530+ZSTACK

Zhibin Qian

Other Parts Discussed in Thread: CC2530

IN ZSTACK, there is one define "NWK_MAX_DEVICE_LIST", and in one network the coordinator can only supoort NWK_MAX_DEVICE_LIST devices.

Because changing NWK_MAX_DEVICE_LIST by 1 changes the size of the association table by 18 bytes,

so can we conclusion that using CC2530 can only support (remain RAM bytes/18 bytes) number devices in one ZigBee network? And it will not greater than 100?

Hi,

I am curious about this topic too. Not sure, but "NWK_MAX_DEVICE_LIST" is the maximum number of devices that can be supported by ONE router or coordinator. I think that the maximum devices in your network depends on the number of routers you use (once the network has been estabilished the routers are acting the same as the coordinator). The Zigbee short address length is 16 bit long so there is a huge address space for a network.
