Bluez 与我的 BLE 遥控器配对后崩溃答案

【问题标题】：Bluez crashes after pairing an with my BLE RemoteBluez 与我的 BLE 遥控器配对后崩溃
【发布时间】：2020-05-13 03:43:19
【问题描述】：

我有一个之前在另一个系统上使用过的蓝牙遥控器，现在正在运行 4.52 BLUEZ，当我与遥控器配对时，bluetoothctl 出现错误。

连接蓝牙ctl

pi@marcophone:~$ sudo bluetoothctl

这里我已经成功连接到遥控器了

在此之后bluetoothctl 失去连接

版本：

bluetoothctl: 5.52
pi@marcophone:~$

我还应该在这里看到一个条目：/dev/input/event*，但只有/dev/input/mice。

我知道我在 bluez 5.50 中得到了这个工作，所以它可能是 bluez 5.52 中的一个问题。

在进行研究时，我确实在/lib/systemd/system/bluetooth.service 中添加了以下三个选项：

ExecStart=/usr/libexec/bluetooth/bluetoothd --compat --noplugin=sap -E

【问题讨论】：

服务以status=11/SEGV（分段错误）退出的事实表明这是BlueZ中的一个错误，因此最好向开发人员报告。
正如 tttapa 提到的，这很可能是 BlueZ 中的一个错误，因为您遇到了分段错误，而且它与旧版本的 BlueZ 一起工作。现在，您可以尝试在开始时运行“bluetoothctl --agent KeyboardDisplay”，看看会发生什么？
@YoussifSaeed: sudo bluetoothctl --agent KeyboardDisplay 不做任何事情。而且 bluetoothctl 不会启动，只会阻止提示。输入此内容时您会期待什么？

【解决方案1】：

我在另一台机器上得到了这个工作。但是，该机器运行 raspbian buster（4.19.97+ #1294 Thu Jan 30 13:10:54 GMT 2020 armv6l GNU/Linux）。

我在连接和配对遥控器时遇到了一些麻烦，所以我做了以下操作，终于让它工作了：

更新系统

sudo apt update && sudo apt upgrade

更新到最新的 bluez 堆栈

sudo apt-get remove bluez
date && sudo apt-get update && sudo apt-get install libdbus-1-dev libglib2.0-dev libudev-dev libical-dev libreadline-dev -y && 

date && wget www.kernel.org/pub/linux/bluetooth/bluez-5.52.tar.xz &&  tar xvf bluez-5.52.tar.xz && 

date && cd bluez-5.52 && ./configure --prefix=/usr --mandir=/usr/share/man --sysconfdir=/etc --localstatedir=/var --enable-experimental && make -j4 && sudo make install && date && sudo reboot

现在更新服务/lib/systemd/system/bluetooth.service的ExecStart部分如下：

ExecStart=/usr/lib/bluetooth/bluetoothd --compat --noplugin=sap -E

同时更新/etc/bluetooth/main.conf 并在[General] 部分设置Privacy = off。

【解决方案2】：

要升级到较新的bluez堆栈我宁愿使用包，如下

sudo apt install debhelper autotools-dev dh-autoreconf \
    flex  bison libdbus-glib-1-dev  libglib2.0-dev \
    libcap-ng-dev    udev   libudev-dev   libreadline-dev \
    libical-dev  check   dh-systemd     libebook1.2-dev
mkdir bluez
cd bluez
wget https://launchpad.net/ubuntu/+archive/primary/+sourcefiles/bluez/5.55-0ubuntu1.1/bluez_5.55-0ubuntu1.1.dsc 
wget https://launchpad.net/ubuntu/+archive/primary/+sourcefiles/bluez/5.55-0ubuntu1.1/bluez_5.55.orig.tar.xz 
wget https://launchpad.net/ubuntu/+archive/primary/+sourcefiles/bluez/5.55-0ubuntu1.1/bluez_5.55-0ubuntu1.1.debian.tar.xz 
dpkg-source -x bluez_5.55-0ubuntu1.1.dsc 
cd bluez-5.55
dpkg-buildpackage -b
cd ..
sudo dpkg -i *deb

使用包的好处是你可以安装这个东西的其他版本
