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

|
Write: |
|
|
|
<channel> |
|
|
|
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. |
|
|
|
Reading returns the currently active channel, or -1 if |
|
the radio controller is not beaconing. |

Description: |
|
|
|
The application-specific information element (ASIE) |
|
included in this device's beacon, in space separated |
|
hex octets. |
|
|
|
Reading returns the current ASIE. Writing replaces |
|
the current ASIE with the one written. |

Description: |
|
The EUI-48, in colon-separated hex octets, for this |
|
radio controller. A write will change the radio |
|
controller's EUI-48 but only do so while the device is |
|
not beaconing or scanning. |
