The default is 3 superframes 19 (~197 ms) as required by the specification. 20 21What: /sys/class/uwb_rc/uwbN/ 22Date: July 2008 23KernelVersion: 2.6.27 24Contact: linux-usb@vger.kernel.org 25Description: 26 An individual UWB radio controller. 27 28What: /sys/class/uwb_rc/uwbN/beacon 29Date: July 2008 30KernelVersion: 2.6.27 31Contact: linux-usb@vger.kernel.org 32Description: 33 Write: 34 35 <channel> 36 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. 42 43 Reading returns the currently active channel, or -1 if 44 the radio controller is not beaconing. 45 46What: /sys/class/uwb_rc/uwbN/scan 47Date: July 2008 48KernelVersion: 2.6.27 49Contact: linux-usb@vger.kernel.org 50Description: 51 Write: 52 53 <channel> <type> [<bpst offset>] 54 55 to start (or stop) scanning on a channel. <type> is one of: 56 0 - scan 57 1 - scan outside BP 58 2 - scan while inactive 59 3 - scanning disabled 60 4 - scan (with start time of <bpst offset>) 61 62What: /sys/class/uwb_rc/uwbN/mac_address 63Date: July 2008 64KernelVersion: 2.6.27 65Contact: linux-usb@vger.kernel.org 66Description: 67 The EUI-48, in colon-separated hex octets, for this 68 radio controller.
