0016 If no beacons are received from a device for at least
0017 this time, the device will be considered to have gone
0018 and it will be removed. The default is 3 superframes
0019 (~197 ms) as required by the specification.

0033 Write:
0034
0035 <channel>
0036
0037 to force a specific channel to be used when beaconing,
0038 or, if <channel> is -1, to prohibit beaconing. If
0039 <channel> is 0, then the default channel selection
0040 algorithm will be used. Valid channels depends on the
0041 radio controller's supported band groups.
0042
0043 Reading returns the currently active channel, or -1 if
0044 the radio controller is not beaconing.
