Linux BlueZ 4.101允许GATT连接，但不能在Ubuntu上公开GATT服务 [英] Linux BlueZ 4.101 Allows GATT Connection but does not Expose GATT Services on Ubuntu
问题描述
我的目标是在Ubuntu 14.04上使用BlueZ 4.101(而非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，一些人已经确认可以使用它们.例如，帖子中的最后一个答案声称它有效: Bluez:广告服务/gatt服务器例子?
My goal is to use BlueZ 4.101 ( not BlueZ 5.X ) to expose a GATT Server through a USB BLE Dongle ( Cambridge Silicon Radio CSR8510 A10 ) on Ubuntu 14.04. BlueZ 4.101 ships with a gatt-example plugin that several people have confirmed works for them. For example, the last answer in the post claims it works: Bluez: advertise service / gatt server example?
最终，我想在BlueZ 4.101中实现自己的GATT服务器，类似于这篇文章: http://gaiger-programming.blogspot. tw/2015/01/bluetooth-low-energy-customizing-gatt.html
Ultimately, I want to implement my own GATT server in BlueZ 4.101 similar to this post: http://gaiger-programming.blogspot.tw/2015/01/bluetooth-low-energy-customizing-gatt.html
我已经能够使用iPhone查看BLE广告并连接到BLE服务器，但是我看不到BlueZ 4.101随附的GATT Server示例的任何特征或服务.手机上的多个BLE扫描器应用程序显示BLE服务器广告并允许连接，但他们都说此设备没有服务.
I've been able to use my iPhone to see the BLE Advertisements and connect to the BLE server, but I cannot see any characteristics or services for the GATT Server example that comes with BlueZ 4.101. Multiple BLE scanner apps on the phone show the BLE Server advertisements and allow a connection, but they all say this device has no Services.
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，并按照以下说明自行进行了编译:
I've managed to completely remove the package manager's version of BlueZ 4.101 on Ubuntu 14.04 and compile it myself with the following set of instructions:
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:
I then launch the GATT Server like this ( as root ):
#!/bin/sh
killall bluetoothd 2>/dev/null

如果我尝试仅启用1个时间"插件-我收到以下错误，并且该设备不可发现:
If I try to just enable 1 plugin "time" - I get the following error and the device is not discoverable:

现在，手机可以看到并连接到加密狗，但是却看不到任何服务或任何特征:
Now the Phone can see and connect to the dongle, but cannot ever see any services or read any characteristics:
我如何才能使GATT服务器完全正常工作并进行适当的广告宣传，并使其与服务和特性进行交互?
How do I get the GATT Server to completely work and advertise properly and allow it's services and characteristics to be interacted with?
推荐答案
显然，这与所使用的无线电有关. CSR BLE加密狗不能用作GATT服务器.我使用德州仪器(Texas Instruments)WL1271在另一块板上完成了这些确切步骤，并且可以正常工作！ iPhone可以看到GATT服务/特征.
Apparently this has to do with the radio being used. The CSR BLE Dongle cannot perform as a GATT Server. I did these exact steps on another board with a Texas Instruments WL1271 and it works! The iPhone can see the GATT Service / Characteristics.
