Let’s say I merely want to know if all devices are connected to the network and none of them have been turned off. Is a query broadcast and acknowledgment broadcast sufficient?
I am not sure, if I understood well your question. I think, that better solution is to do a new discovery of your IQMESH net, to obtain information, which modules are discovered. Personaly, I do not think, that FRC is good method for testing connected nodes, because, if you have swithed-off node, which is router for some segmet of your net (alone router), you are not able to ask all modules connected through this router. But of course, it depends on topology a redundancy of paths.

In the case of an IQMesh net, is the loss of a node detected instantaneously?
I think no.
