Raspberry Pi 安裝 USB Bluetooth Dongle

1. 安裝藍芽相關程式

> sudo apt-get update
> sudo apt-get upgrade
> sudo apt-get autoremove
> sudo atp-get install bluetooth bluez-utils blueman


2. 確認藍芽是否正常運作

> lsusb
Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 004: ID 0a5c:200a Broadcom Corp. BCM2035 Bluetooth dongle

> /etc/init.d/bluetooth status
[ ok ] bluetooth is running.


3. 掃描其他藍芽裝置

> hcitool scan

Scanning ...
        78:A3:*:*:*:22       iphone4  (找到開啟藍芽的iPhone4, 您掃描到的裝置MAC Address 78:A3:*:*:*:22應該不同)


4. Ping一下其他藍芽裝置 (本例為iPhone4)

> sudo l2ping -c 3  78:A3:*:*:*:22 
(輸入掃描到的裝置MAC Address 78:A3:*:*:*:22) 

Ping: 78:A3:B4:97:A0:22 from 00:02:*:*:*:D4 (data size 44) ...
