我使用串口通道2.我的设置来自/etc/bluetooth/rfcomm.comm
$cat /etc/bluetooth/rfcomm.conf
rfcomm0 {
# Automatically bind the device at startup
bind yes;
# Bluetooth address of the device
device 30:17:C8:A1:18:BF;
# RFCOMM channel for the connection
channel 2;
# Description of the connection
comment "SE Elm (Uralbash)";
}
接下来我尝试连接到串口。
$sudo rfcomm bind rfcomm0
$rfcomm
rfcomm0: 30:17:C8:A1:18:BF channel 2 clean
$sudo cat /dev/rfcomm0
cat: /dev/rfcomm0: Host is down
$sudo /etc/init.d/bluetooth restart
[ ok ] Stopping bluetooth: /usr/sbin/bluetoothd.
[ ok ] Starting bluetooth: bluetoothd.
$sudo cat /dev/rfcomm0
cat: /dev/rfcomm0: Host is down
$sudo rfcomm release 0
$sudo /etc/init.d/bluetooth restart
[ ok ] Stopping bluetooth: /usr/sbin/bluetoothd.
[ ok ] Starting bluetooth: bluetoothd.
$rfcomm show 0
rfcomm0: 30:17:C8:A1:18:BF channel 2 clean
$rfcomm connect 0
Can't connect RFCOMM socket: Host is down
