Description:
Write:
- <channel> [<bpst offset>]
+ <channel>
- to start beaconing on a specific channel, or stop
- beaconing if <channel> is -1. Valid channels depends
- on the radio controller's supported band groups.
+ 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.
- <bpst offset> may be used to try and join a specific
- beacon group if more than one was found during a scan.
+ Reading returns the currently active channel, or -1 if
+ the radio controller is not beaconing.
