Linux bluetooth基本操作

支持 usb_hci rfcomm 協定軟體 bluez 載入hci_usb、 rfcomm模組# modprobe hci_usb # modprobe rfcomm 插入usb receriver # hciconfig hci0 up 指令啟動裝置

Ping一下看看： （指令為l2ping,l是小寫的L而不是數字1) ）

本地主機配置文件(主機名等參數)： /etc/bluetooth/hcid.conf
....
# Default link mode
# none - no specific policy
# accept - always accept incoming connections
# master - become master on incoming connections,
# deny role switch on outgoing connections
#lm accept; #改成註解 lm accept,master #這邊設定為伺服模式 ....
PIN配對碼所在文件： /etc/bluetooth/pin 我設在/bin/bluepin
內容
#!/bin/sh echo
"PIN:0000"
加載配置文件： #hcid -f /etc/bluetooth/hcid.conf
透過rfcomm連線 #rfcomm connect /dev/rfcomm0 00:0E:07:1C:AE:1D ﹍(參數設定通道) Connected /dev/rfcomm0 to 00:0B:0D:85:13:53 on channel 1 Press CTRL-C for hangup 用串口查看裝置傳輸內容 #minicom -s set

Bluez-移植問題

http://www.yuanma.org/data/2006/0607/article_699.htm 主要都是由這篇文章，源頭dennis以下是我的問題編譯bluez函式庫（版本：Bluez-libs-3.36）沒有問題，但在下面產生函式庫就出現下面的問題（待解）/usr/local/arm/3.4.1/bin/arm-linux-gcc -o -shared -o libbluetooth.so.1.0.17 bluetooth.o hci.o sdp.oerror：/usr/local/arm/3.4.1/lib/gcc/arm-linux/3.4.1/../../../../arm-linux/bin/ld: bluetooth.o: Relocations in generic ELF (EM: 3)bluetooth.o: could not read symbols: File in wrong formatcollect2: ld returned 1 exit status
search：http://www.linuxeden.com/forum/thread-159396-1-6.html接下來只要作函式庫連結在放到arm核心中就可以了# ln -s libbluetooth.so.1.0.17 libbluetooth.so# ln -s libbluetooth.so.1.0.17 libbluetooth.so.1
http://www.yuanma.org/data/2006/0607/article_699.htm（參考文章）
在基本核心內已經有包括bluez，hci_usb，rfcomm...等基本模組，再來函式庫及檔案系統中的bin操作測試版本同lib一樣 bluez-utils-3.36
checking for DBUS... noconfigure: error: D-Bus library is required作blue-unit設定時DBUS ERROR
改換版本bluez-utils-2.25+bluez-libs-2.25（都給他試試看）做了以下設定：libs./configure --prefix=/usr --host=armv4l CC=/usr/local/arm/3.4.1/bin/arm-linux-gccmake;make installutils./configure --prefix=/usr/bluetooth --includedir=/usr/include/bluetooth --libdir=/usr/lib --with-bluez=/usr/bluetooth --disable-test --disable-cups --disable-pcmia --host=armv4l CC=/usr/local/arm/3.4.1/bin/arm-linux-gcc CPP=/usr/local/arm/3.4.1/bin/arm-linux-cpp AR=/usr/local/arm/3.4.1/bin/arm-linux-ar STRIP=/usr/local/arm/3.4.1/bin/arm-linux-strip RANLIB=/usr/local/arm/3.4.1/bin/arm-linux-ranlib LD=/usr/local/arm/3.4.1/bin/arm-linux-ldmake;make install在我的/usr/bluetooth裡面就看得到bin及sbin了接下來要丟到機器上試試看～～ 結果沒問題照藍芽的基本操作來設定也是接收的到gps的訊號的！ 上面問題就無視了＝＝＋
檔案系統預設方面有點問題，在設定device時要etc的rfcomm.conf不能設定初始化，全部用成註解
還有在/.bashrc 的檔案內容新增
ln -sf /dev/bluetooth/rfcomm/0 /dev/rfcomm0
重新啟動, 再照上面操作結果ok！
