Coordinator does not respond to many-to-one request

My network consists of 1 coordinator, 10 or so routers and 50 or so end devices.

I am using a mixture of many-to-one and source routing to control most of the network from one of the routers.

When I first setup the network the coordinator would respond to many-to-one route requests. Now it does not do so. I’ve done a power reset and updated some settings, but this does not affect whether it responds.

Is this expected behavior? Seems that this should respond to the many-to-one (AR) requests).

Sounds like the Coordinator is not on your network or you are not issuing the AR command that often. To resolve, try issuing a network reset with a 1 and then re-issue the AR command.
