Broadcasting Data to All Nodes.
Broadcasting Data to All Nodes.
You can broadcast the following data to all nodes on your MeshScape system:
• The time to which all nodes will synchronize their clocks
• Ultra Low Power (ULP) settings defining wakeup interval and duty cycle for all nodes
The following procedure describes how to broadcast data to all nodes (see Figure 3-22):
1. From MeshScape Network Monitor, select Network>Broadcast. The Broadcast window
is opened.
2. Configure the following broadcast settings:
– Synchronize device clock: Set the time with which the node clocks are to
synchronize. Mark the Use host clock check box to broadcast the time set on the
host PC on which the MeshScape Network Monitor is running, or alternatively, enter
the date and time to broadcast.
– Wakeup interval: The wakeup interval determines the Mesh Node wakeup cycle.
Minimum value for the wakeup interval is 60000 milliseconds, and the maximum
value is 6540000 milliseconds.
– Duty ratio: The duty ratio determines how long the Mesh Node stays awake and
how long it sleeps during each wakeup interval. The duty ratio is defined as
100*(awake time)/(wakeup interval). Note that the wakeup interval = awake time +
sleep time. The duty ratio has no unit.
The units for specifying the duty cycle is tenths of a percent. The recommended
Minimum value for the duty ratio is 5 (represent 0.5%), and the Maximum value is
1000 (represents 100.0%) set in increments of 5.
3. Select Validate to verify your ULP settings are valid and within range.
4. Select OK to save the settings and exit the Broadcast window.
Note:
The broadcast feature is not supported in this release of the RK-5424-5 Reference
Kit but will be supported in future releases.
