打開藍(lán)牙

再Services里面找到藍(lán)牙選項输涕，并打開庶灿。

下面要用ssh進行控制

打開終端（mac晋渺，linux煞额；windows請度娘）

sudo ssh root@樹莓派ip地址

如果秘鑰出問題

sudo rm -rf /var/root/.ssh/known_hosts

然后再連接

檢查藍(lán)牙服務(wù)狀態(tài)

systemctl status bluetooth

應(yīng)該能夠看到下面的信息

Mar 08 02:28:49 Lakka systemd[1]: Started Bluetooth service.

Mar 08 02:28:49 Lakka bluetoothd[522]: Bluetooth daemon 5.43

Mar 08 02:28:49 Lakka bluetoothd[522]: Starting SDP server

Mar 08 02:28:49 Lakka bluetoothd[522]: kernel lacks bnep-protocol support

Mar 08 02:28:49 Lakka bluetoothd[522]: System does not support network plugin

Mar 08 02:28:49 Lakka bluetoothd[522]: Bluetooth management interface 1.14 initialized

Mar 08 02:32:54 Lakka bluetoothd[522]: No agent available for request type 0

Mar 08 02:32:54 Lakka bluetoothd[522]: device_request_pin: Operation not permitted

如果出現(xiàn)下面信息：

● bluetooth.service - Bluetooth service

? Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)

? Active: inactive (dead)

Condition: start condition failed at Tue 2015-04-07 19:35:48 UTC; 1min 59s ago

? ? ? ? ? ConditionPathExists=/storage/.cache/services/bluez.conf was not met

嘗試手動開啟藍(lán)牙服務(wù)

systemctl enable bluetooth

systemctl start bluetooth

再檢查藍(lán)牙狀態(tài)重復(fù)上面的步驟

如果藍(lán)牙還是報錯袭景，請創(chuàng)建配置文件并重啟藍(lán)牙服務(wù)

touch /storage/.cache/services/bluez.conf

systemctl start bluetooth

配對藍(lán)牙

運行藍(lán)牙控制模塊

bluetoothctl

一個藍(lán)牙提示符[bluetooth]#將會出現(xiàn)挡育，輸入下面的命令

agent on

default-agent

power on

discoverable on

pairable on

scan on

打開你的8Bitdo 控制器模式1. 將會顯示下面的信息

Discovery started

[CHG] Controller B8:27:EB:48:30:22 Discovering: yes

[NEW] Device E4:17:D8:3E:6A:7D 8Bitdo NES30 Pro

連接手柄绒瘦，輸入下面的命令

connect <device_addr>

將會顯示下面的信息

[bluetooth]# connect E4:17:D8:3E:6A:7D

Attempting to connect to E4:17:D8:3E:6A:7D

[CHG] Device E4:17:D8:3E:6A:7D Connected: yes

[CHG] Device E4:17:D8:3E:6A:7D Paired: yes

Connection successful

信任設(shè)備

trust <device_addr>

完工称簿。

測試再重啟開機后手柄會自動連接。如果失去連接請重啟手柄和樹莓派惰帽。再不行就重新連接憨降。

connect <device_addr>
