ble python 成功的例子 创建GATT服务 BLUEZ 5.47

工欲善其事，必先利其器

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

解决 Failed to obtain handles for "Service Changed" characteristic

-E 应该能解决问题

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

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
