  12. KernelVersion: 2.6.27
  13. Description:
  14. If no beacons are received from a device for at least
  15. this time, the device will be considered to have gone
  16. and it will be removed. The default is 3 superframes
  17. (~197 ms) as required by the specification.

  28. Description:
  29. Write:
  30. <channel>
  31. to force a specific channel to be used when beaconing,
  32. or, if <channel> is -1, to prohibit beaconing. If
  33. <channel> is 0, then the default channel selection
  34. algorithm will be used. Valid channels depends on the
  35. radio controller's supported band groups.
  36. Reading returns the currently active channel, or -1 if
  37. the radio controller is not beaconing.

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

  55. to start (or stop) scanning on a channel. <type> is one of:
  56. == =======================================
  57. 0 scan
  58. 1 scan outside BP
  59. 2 scan while inactive
  60. 3 scanning disabled
  61. 4 scan (with start time of <bpst offset>)

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