python cmap 蓝黑 python bluez

发现是偶然事件，正确的做法可能要修改bluez里面服务的注册方式，把ble的服务发现注册到sdp。具体做法不清楚。但是肯定要修改源码。

使用未知的工具,现在一个良好的平台上走通了整条道路.
然后建设新的道路的时候,心如明镜... ...
未来不再迷茫.

废话不多说,首先买一块raspberry Pi.
raspberry Pi.是可以在上面编译程序的东西.
软件十分完善.

以pi而不是以root运行

在家目录运行

sudo bluetoothd -n -d --compat --plugin=time --experimental

在test的目录下.执行

./example-gatt-server

在家目录运行

sudo hciconfig hci0 up

在家目录运行

sudo hciconfig hci0 leadv

测试的androidapp

-E 应该能解决问题
https://git.kernel.org/pub/scm/bluetooth/bluez.git/commit/?id=f558fca8d64e3795b0654a90d343af1dd1d8b33c 可能有帮助

sudo bluetoothd -E -d --noplugin=sap --experimental --compat -n

抱歉有问题... ...

12-12更新

问题初步解决.
是手机的问题.或者说是android手机的问题.
用同事的iPhone手机测试没有问题.python 调用的GATT服务都出来了.
测试过程. rpi3b 通过 bluetoothctl 连接 OPENWRT 的bluetooth ble服务
首先在 openwrt 上
第一步:bluetoothd -n -d --compat --experimental -------- -n -d 好像是和调试信息相关的参数. --compat 适合 sdptool 相关的参数 否则会报一个错误. --experimental 是 bluez 的ble相关一定要加入的参数.而且在编译
bluez的时候参数也要参考README写下 experimental 的相关参数.
第二步:bluetoothctl 2.1步:power on 2.2步:agent on 2.3步:default-agent 2.4步:list ----------显示自己的系统下挂在的设备.
2.5步:advertise on -------启用ble 模式猜想 :-)
2.6步:``
第三步: 进入bluez目录test目录python example-gatt-server

rpi3B步骤
第一步: bluetoothctl
1.1步: connect EC:3D:FD:3E:30:91
1.2步:list-attributes ------ 显示所有的GATT服务.
1.3步:select-attribute 0000180f-0000-1000-8000-00805f9b34fb
1.4步:select-attribute /org/bluez/hci0/dev_EC_3D_FD_3E_30_91/service0022/char0023
1.5步:read

初步完结撒花... ...
一般问题解析
Failed to connect: org.bluez.Error.InProgress
这个问题,应该是作为连接机器,因为运行着程序关闭这个程序就可以了.

rpi3b显示的所有的服务信息
