15Description:
16 If no beacons are received from a device for at least
17 this time, the device will be considered to have gone
18 and it will be removed. The default is 3 superframes
19 (~197 ms) as required by the specification.

33 Write:
34
35 <channel>
36
37 to force a specific channel to be used when beaconing,
38 or, if <channel> is -1, to prohibit beaconing. If
39 <channel> is 0, then the default channel selection
40 algorithm will be used. Valid channels depends on the
41 radio controller's supported band groups.
42
43 Reading returns the currently active channel, or -1 if
44 the radio controller is not beaconing.
