generally keeps the default port 1
. Only in remote configuration, the target port needs to be changed to port 14, and
the other ports have no function yet.
Multicast radius <rad>
is generally
kept at the default level 2
. The larger the
multicast radius <rad>
is, the larger the
coverage area is.
CSMA random avoidance time<rng>
generally keeps the default value of 127
(random avoidance time is 0~127ms).
The longer the random avoidance time, the slower the network response speed, but the lower the possibility of
conflict. If you want to modify this time, you need to pay attention to the response time and conflict probability of
the entire network.
It is generally not recommended to shorten this time.
The maximum number of consecutive failures <score>
is
generally kept at the default value of 3
.
The maximum
number of consecutive failures <score>
will affect the probability of re-establishing routes.
The smaller the maximum number of consecutive failures <score>
is, the shorter the time it takes to re-establish the
route when a link fails or the communication is abnormal. However, re-establishing the route takes a certain amount of
time, so it is generally sufficient to keep the default. When communication is successful, the current number of failures
will be reset.
The RF automatic reset time <reset_time>
generally keeps the default value of 5 minutes
. When data is received,
the radio frequency automatic reset time will be reset, which will not affect normal data transmission. This time can
be shortened in places with severe environmental interference. Setting it to 0 minutes will turn off the automatic
restart function.
The default values of broadcast filter timeout <time>
at different airspeeds are 15s, 30s, and 60s respectively. When
duplicate data frames are received within the
broadcast filtering timeout <time>
,
they will be filtered.
It is not
recommended to shorten this time.
The default values of request response timeout <time>
at different airspeeds are 2.5s, 5s, and 15s respectively.
NO ACKUnder unicast, the target device needs to return a response ACK. If it gets a response ACK from the target
address, it will return SUCCESS immediately. Otherwise, it will wait for the
request response timeout <time>
to end
before returning NO ACK.
The more levels of routing devices passed through, the longer
the request response timeout <time>
should be.
Under the default parameters, about 5 levels of routing devices can be supported.
The default values of routing request timeout <time>
at different airspeeds are 2.5s, 5s, and 15s respectively.
Under unicast, you need to initiate a routing request first, collect the routing information of each device within
the
routing request timeout <time>
, and then initiate another data request after the end.
The routing request timeout <time>
needs to cover the entire process from the initiation of the routing request to the
complete completion of the network. If the route is not successfully established, NO ROUTER will be returned.
The greater the number of devices, the longer
the routing request timeout <time>
should be. Under the default
parameters, about 50 devices can be supported to establish routes. More than 50 devices need to extend this time through
instructions.
When "OUT OF CACHE" is returned, it means that the sending buffer is full. The sending buffer area can cache 5
items. Under normal circumstances, the buffer area will not be full. It will only occur when the interval between
consecutive sendings is too fast, and all sending data buffers will be forcibly cleared inside the module.
The network protocol layer uses data RSSI to optimize the entire network link. The routing nodes will automatically
select the best routing nodes for routing. Users no longer need to consider signal strength.
