Configure an indirect messaging coordinator

A device becomes an indirect messaging coordinator once CE (Device Role) = 1 and SP (Cyclic Sleep Period) is not 0. We recommend ensuring that SP and ST are set to the same values on the indirect messaging coordinator and end device, even if the indirect messaging coordinator is not configured to sleep. This is to allow the indirect messaging coordinator to send messages directly if it knows the end device is awake and sleeping cyclically.

If you are going to use a Master/Slave network with indirect messaging, ensure that the indirect messaging coordinator is also the network coordinator by allowing association (set bit 2 of A2 (Coordinator Association) to 1).
