Ubuntu17.10:蓝牙不断崩溃
Ubuntu17.10:蓝牙不断崩溃
提问于 2018-03-12 17:28:23
我有Ubuntu17.10联想T540p。我连接了BT耳机CEL F5A。它具有Bt4.0的功能，崩溃时使用的配置文件是HSP/HFP (可怕的声音+麦克风)。
时不时的，蓝牙会关闭。然后我就得把它打开重新连接耳机。我不知道是什么原因。下面是我在dmesg中看到的。我不知道条目是在事件之前还是之后，可能是在(重新连接)之后。
我怎样才能使连接更加稳定？我没有其他BT设备连接。

您可以尝试更改一些参数。
echo "options iwlwifi bt_coex_active=0 swcrypto=1 11n_disable=8" | sudo tee -a /etc/modprobe.d/iwlwifi.conf重新启动
