首先, 你必须发现设备的BDADDR. 这可能打印在外包装盒上, 但是要让设备可以识别和用合适的控制器执行设备质询的最简单的方式是:
代码: 全选
% btconfig ubt0 inquiry
Device Discovery on ubt0 .... 1 response
1: bdaddr 00:0a:95:45:a4:a0 (unknown)
: name "Apple Wireless Keyboard"
: class: [0x002540] Peripheral Keyboard <Limited Discoverable>
: page scan rep mode 0x01
: page scan period mode 0x00
: page scan mode 0x00
: clock offset 18604为了使用简便, 你可将地址加到 /etc/bluetooth/hosts 文件中, 这样你可以使用键盘的别名:
代码: 全选
# echo "00:0a:95:45:a4:a0 keyboard" >>/etc/bluetooth/hosts现在, 你可以质询这个键盘, 它接受连接前可能需要认证。需要在这个键盘上输入PIN, 而我们可以使用 btpin(1) 程序生成一个随机的PIN.
代码: 全选
% btpin -d ubt0 -a keyboard -r -l 8
PIN: 18799632
# btdevctl -d ubt0 -a keyboard -s HID
< ENTER PIN ON BLUETOOTH KEYBOARD NOW >

End collection这里告诉你这个键盘回应了一个SDP质询, 并且显示了这个设备的性能. 注意默认已经启用了加密, 因此对蓝牙键盘来说加密连接是强制性的. 你现在可以附加到系统上:
代码: 全选
# btdevctl -d ubt0 -a keyboard -s HID -A这会在系统控制台上生成一些信息:
bthidev1 at bthub0 remote-bdaddr 00:0a:95:45:a4:a0 link-mode encrypt
btkbd0 at bthidev0 reportid 1
wskbd1 at btkbd0 mux 1
wskbd1: connecting to wsdisplay0
bthidev1: connected
然后键盘就可以工作了.
这个设备的性能被储存在 btdevctl(8)里, 并在系统启动时加载这个键盘, 在 /etc/bluetooth/btdevctl.conf 中添加一个项并确保 /etc/rc.conf 文件中包含了 btdevctl=YES. 加载时bthidev(4) 设备驱动程序将尝试连接一次, 但是如果此时键盘不可用, 你可能会发现按下一个键会激活键盘并初始化与原主机的连接。
