【问题描述】：
我的目标是在 Ubuntu 14.04 上使用 BlueZ 4.101（不是 BlueZ 5.X）通过 USB BLE 加密狗（Cambridge Silicon Radio CSR8510 A10）公开 GATT 服务器。 BlueZ 4.101 附带了一个 gatt-example 插件，一些人已经确认该插件适用于他们。例如，帖子中的最后一个答案声称它有效：Bluez: advertise service / gatt server example?
最终，我想在 BlueZ 4.101 中实现我自己的 GATT 服务器，类似于这篇文章： http://gaiger-programming.blogspot.tw/2015/01/bluetooth-low-energy-customizing-gatt.html
我已经能够使用我的 iPhone 查看 BLE 广告并连接到 BLE 服务器，但是我看不到 BlueZ 4.101 附带的 GATT 服务器示例的任何特征或服务。手机上的多个 BLE 扫描仪应用程序显示 BLE Server 广告并允许连接，但都说此设备没有服务。
我已经设法在 Ubuntu 14.04 上完全删除了软件包管理器的 BlueZ 4.101 版本，并使用以下说明自行编译：
sudo apt-get remove --purge bluez* -y
sudo apt-get install bison byacc flex -y
wget http://www.kernel.org/pub/linux/bluetooth/bluez-4.101.tar.gz
tar xvf bluez-4.101.tar.gz
cd bluez-4.101
sudo service bluetooth stop
sudo make clean
sudo make distclean
sudo ./configure CFLAGS='-Wall -Wextra -O2 -Wno-error' --prefix=/usr --enable-maintainer-mode
sudo make all
sudo make install
sudo vim /etc/bluetooth/main.conf
# Enable the GATT functionality. Default is false
EnableGatt = true
# Enable the GATT Attribute Server. Default is false, because it is only
# useful for testing. Attribute server is not enabled over LE if EnableLE
# is false.
AttributeServer = true
然后我像这样（以 root 身份）启动 GATT 服务器：
#!/bin/sh
killall bluetoothd 2>/dev/null

bluez-4.101/mgmt/btmgmt -i hci1 power off

sleep 3

如果我尝试仅启用 1 个插件“时间” - 我收到以下错误并且设备不可发现：

现在手机可以看到并连接到加密狗，但永远看不到任何服务或读取任何特征：
如何让 GATT 服务器完全正常工作并正确发布广告，并允许与之交互的服务和特性？
