maximum number of children in Z-stack 3.0

Other Parts Discussed in Thread: Z-STACK

I was reading through bunch of posts but I didn't find the definite answer to this question:

What is the maximum number of children a parent can have in Zstack 3.0 using stochastic addressing?

It was limited to 32 children in distributed addressing scheme, but reading Zstack specifications, I can not find the explicit number for stochastic addressing.

I am asking this in order to see if it is possible to have for example 100 end devices connected directly to coordinator, and not using any router.

It would save some money:)

    The max child device on Z-Stack is defined by NWK_MAX_DEVICE_LIST (default is 20) in nwk_globals.h and this is the constrain of system RAM/Flash. It's nothing to do with Zigbee spec. According to my experience, it's not possible to have 100 nodes connected directly to coordinator.
