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/ASIE 47Date: August 2014 48KernelVersion: 3.18 49Contact: linux-usb@vger.kernel.org 50Description: 51 52 The application-specific information element (ASIE) 53 included in this device's beacon, in space separated 54 hex octets. 55 56 Reading returns the current ASIE. Writing replaces 57 the current ASIE with the one written. 58 59What: /sys/class/uwb_rc/uwbN/scan 60Date: July 2008 61KernelVersion: 2.6.27 62Contact: linux-usb@vger.kernel.org 63Description: 64 Write: 65 66 <channel> <type> [<bpst offset>] 67 68 to start (or stop) scanning on a channel. <type> is one of: 69 70 == ======================================= 71 0 scan 72 1 scan outside BP 73 2 scan while inactive 74 3 scanning disabled 75 4 scan (with start time of <bpst offset>) 76 == ======================================= 77 78What: /sys/class/uwb_rc/uwbN/mac_address 79Date: July 2008 80KernelVersion: 2.6.27 81Contact: linux-usb@vger.kernel.org 82Description: 83 The EUI-48, in colon-separated hex octets, for this 84 radio controller. A write will change the radio 85 controller's EUI-48 but only do so while the device is 86 not beaconing or scanning. 87 88What: /sys/class/uwb_rc/uwbN/wusbhc 89Date: July 2008 90KernelVersion: 2.6.27 91Contact: linux-usb@vger.kernel.org 92Description: 93 A symlink to the device (if any) of the WUSB Host 94 Controller PAL using this radio controller. 95 96What: /sys/class/uwb_rc/uwbN/<EUI-48>/ 97Date: July 2008 98KernelVersion: 2.6.27 99Contact: linux-usb@vger.kernel.org 100Description: 101 A neighbour UWB device that has either been detected 102 as part of a scan or is a member of the radio 103 controllers beacon group. 104 105What: /sys/class/uwb_rc/uwbN/<EUI-48>/BPST 106Date: July 2008 107KernelVersion: 2.6.27 108Contact: linux-usb@vger.kernel.org 109Description: 110 The time (using the radio controllers internal 1 ms 111 interval superframe timer) of the last beacon from 112 this device was received. 113 114What: /sys/class/uwb_rc/uwbN/<EUI-48>/DevAddr 115Date: July 2008 116KernelVersion: 2.6.27 117Contact: linux-usb@vger.kernel.org 118Description: 119 The current DevAddr of this device in colon separated 120 hex octets. 121 122What: /sys/class/uwb_rc/uwbN/<EUI-48>/EUI_48 123Date: July 2008 124KernelVersion: 2.6.27 125Contact: linux-usb@vger.kernel.org 126Description: 127 128 The EUI-48 of this device in colon separated hex 129 octets. 130 131What: /sys/class/uwb_rc/uwbN/<EUI-48>/IEs 132Date: July 2008 133KernelVersion: 2.6.27 134Contact: linux-usb@vger.kernel.org 135Description: 136 The latest IEs included in this device's beacon, in 137 space separated hex octets with one IE per line. 138 139What: /sys/class/uwb_rc/uwbN/<EUI-48>/LQE 140Date: July 2008 141KernelVersion: 2.6.27 142Contact: linux-usb@vger.kernel.org 143Description: 144 Link Quality Estimate - the Signal to Noise Ratio 145 (SNR) of all packets received from this device in dB. 146 This gives an estimate on a suitable PHY rate.
