If no beacons are received from a device for at least
|

this time, the device will be considered to have gone

and it will be removed. The default is 3 superframes

Write:
|
|
|
|
<channel>
|
|
|
|
to force a specific channel to be used when beaconing,
|
|
or, if <channel> is -1, to prohibit beaconing. If
|
|
<channel> is 0, then the default channel selection
|
|
algorithm will be used. Valid channels depends on the
|
|
radio controller's supported band groups.
|
|
|
|
Reading returns the currently active channel, or -1 if
|
|
the radio controller is not beaconing.
