Network commands
The following commands are network commands.
CE (Node Messaging Options)
The routing and messaging mode bit field of the device.
A routing device repeats broadcasts. Indirect Messaging Coordinators do not transmit point-to-
multipoint unicasts until an Indirect Messaging Poller requests them. Setting a device as an Indirect
Messaging Poller causes it to regularly send polls to its Indirect Messaging Coordinator. Nodes can
also be configured to route, or not route, multi-hop packets.
Bit Description
Bit 0 Indirect Messaging Coordinator enable. All point-to-multipoint unicasts will be held
until requested by a polling end device.
Bit 1 Disable routing on this node. When set, this node will not propagate broadcasts or
become an intermediate node in a DigiMesh route. This node will not function as a
repeater.
Bit 2 Indirect Messaging Polling enable. Periodically send requests for messages held by the
node’s coordinator.
Note Bit 0 and Bit 2 cannot be set at the same time.
Parameter range
0 - 6
Default
0
BH (Broadcast Hops)
The maximum transmission hops for broadcast data transmissions.
If you set BH greater than NH, the device uses the value of NH. Both variants of firmware support this
command.
Parameter range
0 - 0x20
Default
0
NH (Network Hops)
Sets or displays the maximum number of hops across the network. This parameter limits the number
of hops. You can use this parameter to calculate the maximum network traversal time.
You must set this parameter to the same value on all nodes in the network.
Both variants are supported.
