| 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. | |
