15 | Description: | |
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. | |

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. | |
c8cf2465 | 42 | |
6fae35f9 DV |
43 | Reading returns the currently active channel, or -1 if |
44 | the radio controller is not beaconing. | |
