發現是偶然事件，正確的做法可能要修改bluez里面服務的注冊方式，把ble的服務發現注冊到sdp。具體做法不清楚。但是肯定要修改源碼。

未來不再迷茫.
廢話不多說,首先買一塊raspberry Pi.
raspberry Pi.是可以在上面編譯程序的東西.
軟件十分完善.
以pi而不是以root運行
在家目錄運行
sudo bluetoothd -n -d --compat --plugin=time --experimental
在test的目錄下.執行
./example-gatt-server
在家目錄運行

抱歉有問題... ...

問題初步解決.
是手機的問題.或者說是android手機的問題.
用同事的iPhone手機測試沒有問題.python 調用的GATT服務都出來了.
測試過程. rpi3b 通過 bluetoothctl 連接 OPENWRT 的bluetooth ble服務
首先在 openwrt 上
第一步:bluetoothd -n -d --compat --experimental -------- -n -d 好像是和調試信息相關的參數. --compat 適合 sdptool 相關的參數 否則會報一個錯誤. --experimental 是 bluez 的ble相關一定要加入的參數.而且在編譯
bluez的時候參數也要參考README寫下 experimental 的相關參數.
第二步:bluetoothctl
2.1步:power on
2.2步:agent on
2.3步:default-agent
2.4步:list ----------顯示自己的系統下掛在的設備.
2.5步:advertise on -------啟用ble 模式猜想 😃
2.6步:``
第三步: 進入bluez目錄test目錄python example-gatt-server
rpi3B步驟
第一步: bluetoothctl
1.1步: connect EC:3D:FD:3E:30:91
1.2步:list-attributes ------ 顯示所有的GATT服務.
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
初步完結撒花... ...
一般問題解析
Failed to connect: org.bluez.Error.InProgress
這個問題,應該是作為連接機器,因為運行着程序關閉這個程序就可以了.
