折腾了半天终于搞定了,开心
用的是bluez3.36,大概说一下流程
1. 配置/etc/bluetooth/rfcomm.conf
rfcomm0 {
# # Automatically bind the device at startup
bind no;
#
# # Bluetooth address of the device
device XX:XX:XX:XX:XX:XX;
#
# # RFCOMM channel for the connection
channel 1;
#
# # Description of the connection
comment "Example Bluetooth device";
}
2. 关闭本地pin验证
1)
hciconfig hci0 noauth ; # 关闭本地的pin验证
3. 设置连接pin码
编辑/var/lib/bluetooth/XX:XX:XX:XX:XX:XX/pincodes (XX:XX:XX:XX:XX:XX为本地设备地址)
文件格式为:
XX:XX:XX:XX:XX:XX 1234 (XX:XX:XX:XX:XX:XX为目标设备地址)
4. 运行
mknod /dev/rfcomm0 c 216 0
chmod 666 /dev/rfcomm0
rfcomm connect 0;
5. 输出字符到蓝牙串口
echo y>/dev/rfcomm0
