藍牙滑鼠斷開

我正在使用 Debian Jessie（測試）。我有一個藍牙滑鼠（Microsoft Sculpt Comfort），我可以配對並使用它，但是在不活動​​一段時間（大約 10 分鐘）後它停止工作，我必須手動觸摸滑鼠上的設置可發現按鈕並重新-在命令行上配對它。

我在 OS X 上嘗試過的同一滑鼠，它可以工作，所以這不是硬體問題

核心 3.14.12-1 (2014-07-11)

我將滑鼠與此命令配對：

sudo hidd --connect 30:59:B7:72:A5:A7

正確配對後，這是*/var/log/syslog*輸出

Jan  7 15:22:42 desktop hidd: New HID device 30:59:B7:72:A5:A7 (Microsoft Bluetooth Mouse        )
Jan  7 15:22:42 desktop kernel: [103877.102083] hid-generic 0005:045E:07A2.0009: unknown main item tag 0x0

一段空閒時間後，這將列印在同一個日誌文件中：

Jan  7 15:34:34 desktop acpid: input device has been disconnected, fd 20

如果我點擊滑鼠按鈕或移動它，則會列印出來：

Jan  7 15:49:55 desktop bluetoothd[650]: Refusing input device connect: No such file or directory (2)
Jan  7 15:49:56 desktop bluetoothd[650]: Refusing connection from 30:59:B7:72:A5:A7: unknown device

這似乎表明滑鼠仍在工作並試圖告訴作業系統重新連接，但它不能。

這是udevadm info -p響應：

這個問題有3個解決方案。也許甚至將其中的兩個結合起來也可以解決您的問題。

解決方案 1

編輯文件並在塊內/etc/bluetooth/input.conf設置參數。IdleTimeout=0``[General]

root@nwdesktop:~# vim /etc/bluetooth/input.conf


# Configuration file for the input service

# This section contains options which are not specific to any
# particular interface
[General]

# Set idle timeout (in minutes) before the connection will
# be disconnect (defaults to 0 for no timeout)
IdleTimeout=0

重啟藍牙服務：

root@nwdesktop:~# /etc/init.d/bluetooth restart
* Stopping bluetooth                                                    [ OK ] 
* Starting bluetooth                                                    [ OK ]

這將防止由於藍牙滑鼠和鍵盤超時而斷開連接。

解決方案 2

創建一個 udev 規則，避免滑鼠自動掛起

root@nwdesktop:~# vi /etc/udev/rules.d/91-local.rules

ACTION=="add", SUBSYSTEM=="bluetooth", ATTR{product}=="Microsoft Bluetooth Mouse        ", ATTR{power/control}="on"

root@nwdesktop:~# # udevadm control --reload-rules

解決方案 3

這並不讓我感到驕傲，但是……使用您的 hidd connect 命令創建一個腳本：

user@nwdesktop:~# vi /home/user/recconect.sh

#!/bin/bash
sudo hidd --connect 30:59:B7:72:A5:A7

現在，添加到您的 crontab：

root@nwdesktop:~# vi /etc/crontab

*/10   *    *   *   *   root /home/user/recconect.sh

乾杯。
