Starting a network
To start a network, the coordinator must select an operating frequency and PAN ID based on the results
of an active scan. The frequency chosen should be a little-used one and certainly should not have a
network with the same PAN ID. The network is then started by setting the device’s short address and
then issuing a +MSRR start request:
Once you have started the network, you should be able to locate it using a scan from another device such
as a sniffer.
Permitting joining
To allow networks to join a coordinator’s network, its AssocPermit flag must be set:
When a device requests to join, (see next section, Joining a network,) an association indication will be
generated:
The coordinator must then decide whether or not to let the device join and issue a MASS response. If it
is allowed to join, it is assigned a short address and the status value is zero. If not, the status value
should be 0x01 if the PAN is “at capacity” or 0x02 if association is denied.
The short address and long address of the joining device must then be stored in a network membership
table so that the device may rejoin as an orphan at a later date. In addition, the the CapabilityInformation
byte will have to be stored if there are sleepy devices on the network. Otherwise the coordinator will no
know whether it can transmit data immediately to the device (“direct”, i.e. RxOnWhenIdle) or whether
the data should be cached until the device asks for it (“indirect”, i.e. RxOffWhenIdle).
Joining a network
To join a network, a device must first discover it using an active scan. Only networks with their
AssocPermit bit set can be joined.
Once a network has been selected, an association request is made:
