single-node-reboot
timeout-sec=0,15..60000
After power up, a radio attempts to get an RF link with one or more radios. If a radio fails to
get a link up (or drops all existing links), it will perform a complete reset after the timeout
specified in this command. A value of zero is allowed and it turns this feature off.
This feature is useful if you issue a command to a distant radio (over an existing RF link) and
the link drops as a consequence of the command. If that radio now has no other links up it
waits for the "single-node-reboot” and then perform a reset. As a result, the radio reverts to the
saved configuration, allowing it to reestablish the original link.
Examples:
> snr 60
time-division-duplex
sync-mode=off or auto
This parameter selects whether this radio participates in the negotiation of the heartbeat
synchronization to select a single source for the heartbeat. The default
auto mode is
recommended for most applications.
The off mode may be useful in situations where there is a variable and significant delay in the
local Ethernet connecting the several co-located radios. In that case the radios may not be able
to establish synchronization and you may get better results turning off the heartbeat protocol.
See section 2.4.3 for a detailed explanation of the synchronization between co-located radios.
cycle-period-ms= 20 or 40
A cycle period of 20 ms (default) results in lower latencies throughout the network. However
there will be more transitions between transmit and receive resulting in somewhat lower
throughput capacity for the network. A cycle period of 40 ms has the opposite effect.
For small networks a cycle period of 20 ms is usually preferred. If you have a network with
many nodes that are simultaneously active the 40 ms cycle will give you better performance.
The cycle period only needs to be set at the hub or root nodes. All the children will pick up the
cycle period from their parents.
split-outbound-percent=auto or 10 or 20 or 30 or 40 or 50 or 60 or 70 or 80 or 90
This parameter is relevant at the hub or root nodes only. It specifies the percentage of the total
cycle period dedicated to RF outbound transmissions (from parent to children). The remaining
time is dedicated to inbound traffic (from children to parent). You only need to specify this
parameter at the root or the network hub. For all the other nodes, as they join the network they
take the split information from their parent.
In auto mode a parent radio dynamically assigns a split based on the current traffic load in each
direction. This split may be different from cycle to cycle and different at each branch on a tree.
Select fixed splits if you co-locate multiple radios and need to avoid self-interference. You may
also choose a fixed split if your traffic is constant and consistently favors either outbound or
