CC2530 ZStack Message queue behavior on coordinator

Other Parts Discussed in Thread: Z-STACK

Hello

I have question for the message operation on Zigbee coordinator...

Basically  the RF data send to coordinator from devices, the coordinator will receive at MAC layer and reply ACK then pass data to Application layer,

1. is the Zstack dynamic allocate queue buffer to put the message? what if the queue buffer is full, the stack how to do with this received packet? drop it?

2. the MAC reply ACK timing is when get the packet or after put data into queue buffer success?

I am  trying build a network with many sensors, and there are some data missing, I am not sure what is the reason..

    TI employee won't reveal implementation of Z-Stack in public forum. If you need these information, I would suggest you to contact TI local representative. By the way, do you check using packet sniffer if your coordinator does MAC ACK to your sensor when you think the data missing?
