Linux BlueZ 4.101允许GATT连接但不在Ubuntu上公开GATT服务

Question

我的目标是使用BlueZ 4.101（不是BlueZ 5.X）在Ubuntu 14.04上通过USB BLE Dongle（Cambridge Silicon Radio CSR8510 A10）公开GATT服务器。 BlueZ 4.101附带一个 gatt-example 插件，有几个人确认这些插件适用于他们。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，但我看不到BlueZ 4.101附带的GATT Server示例的任何特性或服务。手机上的多个BLE扫描仪应用程序显示BLE服务器广告并允许连接，但他们都说该设备没有服务。

我已经设法在Ubuntu 14.04上完全删除了包管理器的BlueZ 4.101版本，并使用以下一组说明自行编译：

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

sleep 3

如果我尝试启用1个插件＆＃34;时间＆＃34; - 我收到以下错误，设备无法被发现：

现在手机可以看到并连接到加密狗，但是看不到任何服务或读取任何特征：

如何使GATT服务器完全正常工作并正确宣传并允许其与服务和特征进行互动？

Answer 1

显然这与使用的无线电有关。 CSR BLE Dongle无法作为GATT服务器运行。我在德州仪器WL1271的另一块电路板上做了这些准确的步骤，它可以工作！ iPhone可以看到GATT服务/特征。
