How do one verify that messages is routed through the Zigbee network?

Other Parts Discussed in Thread: MSP430F2618, Z-STACK, CC2520

Hi,

Setup : Z-Stack (Zigbeepro) running on 3 SmartRF05 boards and using MSP430F2618 + CC2520. 2 boards configured/compiled as routers and 1 as a coordinator.

all boards runs the Sample app comming with the Z-stack, with only one change : the routers can send a unicast message the the coordinator, in addition to the group message it already can send.

Test setup : coordinator is turned on and have configred the PAN and the routers has joined the network, verified by that the routers can send the group message and the unicast message to the coordinator.

1 router is now moved out of range of the coordinator (verified by sending unicast messages to the coordinator) and router 2 is then placed in the middel range of router 1 and the coordinator.

Okay, and now to the problem: neither the unicast or the group message from router 1 is received by the coordinator even though that the router 2 should route at least the unicast message ??? Shouldn't the system, at least, implicit route the unicast message or have I forgotten somewhere in the compliation a define that enables routing??

    Hi Lars,

    Do you have the capability to test our packet sniffer or Danitreee SNA?

    You can the take a look at the MAC short address and the NWK address of the packets. By using a the Daintree SNA you can also easy obtain a graphical overview of your mesh network to see how packets are routed around in the network visually. 

    Try this

    Enjoy,

    I have the Danitree SNA sw (Z-tool, right?!?) but I can't find any guidance how the HW setup have to be for running z-tool? all I know is, that I need to connect serial, but to what HW?

    My other, not so direct, placed question was : What is is the technical reason when 3 devices, placed free of sight, won't route a unicast message?

    Hi Lars,

    Here are some ideas and comments:

    Daintree SNA is not Z-Tool. Z-Tool is our own test tool.

    Daintree: http://www.daintree.net/

    With respect to your question, my guess is that all your device are join directly to the coordinator due the good link quality. Per default each node in our Z-Stack is configured with 0 dBm output power, so if the nodes are within the same room the will "normally" connect directly to the PAN Coordinator as become a start instead of a mesh.This is an automatic process by Z-Stack.

    Here are few things to test:

    1. Try to reduce outpower

    2. Experiment only (Remove antennas (Reduce radiated power) to generate a mesh within your office area)

    3. Enable Permit Join on the Coordinator to force a one hop mesh with C - R - ED

    2. Try to bring a router out of range to see how far you need move in "real life" for RF environment to generate a one hop mesh.

    BTW:

    Maybe take a look at the short address you can sort this out if you are using Z-Stack 2006/2007 (Non PRO) for example
