问题描述
我有一个新的破坏者形象：
Linux 立体声 5.10.17+ #1414 Fri Apr 30 13:16:27 BST 2021 armv6l GNU/Linux
我确实将 bluez 更新为 bluez 5.52。有趣的是，我的 /var/log/syslog 中有以下条目：
Jun 30 23:15:09stereopida bluetoothd[557]：蓝牙守护进程 5.50
这似乎表明之前安装的 5.50 版本仍然存在。
我在其他机器上做了同样的设置，然后我可以让它工作，但这次似乎有问题。
现在使用 bluetoothctl 我可以看到我的设备并进行配对，但连接立即断开：
[bluetooth]# trust 84:EB:18:0C:92:0F
Changing 84:EB:18:0C:92:0F trust succeeded
[bluetooth]# pair 84:EB:18:0C:92:0F

当我检查日志时，我确实看到以下内容：

在我的 /etc/bluetooth/main.conf 文件中，我做了以下更改：
DiscoverableTimeout = 0
PairableTimeout = 0
ControllerMode = le
Privacy = off
我的 bluetooth.service 的 ExecStart 部分我确实更改为：
ExecStart=/usr/lib/bluetooth/bluetoothd --noplugin=sap -E
Gatttool
sudo gatttool -b 84:EB:18:0C:92:0F --interactive
