7.1.
Energy Level
The coordinator will start a network on a selected channel only if the energy level on that
channel is below a threshold value. The threshold value is set to -45dBm and can be modified by
changing the MAX_SCAN_ENERGY definition in the
mac_scan.c
file (available only with
TIMAC source file distribution). The value of this parameter minus 83 gives the maximum
tolerated energy level in dBm. To ensure that the coordinator will always find a suitable channel
to start the network on, it is recommended that more than one channel is selected.
