Hi Marte

Each of them is within 10m radius from the others.

I want to update some more information that i also try to make the coordinator to send many-to-one routing request and i can see that the node repair is happening. When i capture the message from the node to the coordinator, i can see that it choose a different path. But what i do not understand is that the process of choosing a new route.

So the question is: Is the network suppose to be in many-to-one routing to have the ability to heal itself? And is this happen to every other kinds of routing discovery like table routing, etc ?

Another problem is that when i try to connect, for example, 3 routers around the coordinator directly, then i re-position each of them on a straight line 10m away from each others. The routers in the back of the row did not send route request to find a new way even it fail to send a report attribute message. So How can I fix this ?

Thank you and please reply soon,

Sincerely,

Hi Tu,

How far away from each other are the router devices? Are there remaining routers in radio range?

Best regards,

Marte

Hi Tu,

According to the Zigbee spec, coordinators and routers shall participate in route repair, but initiating route repair is something they may provide, and is not mandatory. I'm not certain how this is handled in the SDK, as I assumed the network repaired itself in case of link failure, but from your issue that appears to not be true. I have forwarded this to our Zigbee team and will come back to you when I get a response.

Best regards,

Marte
