Many-to-One Route Request Indicator - 0xA3
Description
A many-to-one route request is sent as a broadcast message from a concentrator (AR < 0xFF).
When a node receives a many-to-one broadcast, it will create a route table entry for the concentrator,
preventing the need to do a route discovery when sending data to that destination.
Format
The following table provides the contents of the frame. For details on frame structure, see API frame
format.
