dbus学习笔记

0. ready

    dbusaddr=`ls /tmp |grep dbus`

    export DBUS_SESSION_BUS_ADDRESS="unix:path=/tmp/${dbusaddr}"

    启动dbus(根据conf来区别system session)

    dbus-launch --auto-syntax --config-file=/usr/share/dbus-1/session.conf

    dbus-launch --auto-syntax --config-file=/usr/share/dbus-1/session.conf > /tmp/dbusenv.sh

    cat /tmp/dbusenv.sh | grep 'DBUS_SESSION_BUS_ADDRESS=' | awk -F ';' '{print $1}' > /tmp/dbusname

    使用env.sh

    dbusaddr=`cat /tmp/dbusname  | cut -d "'" -f2`

    export DBUS_SESSION_BUS_ADDRESS="${dbusaddr}"

    或者

    export DBUS_SESSION_BUS_ADDRESS=`cat /tmp/dbusname  | cut -d "'" -f2`

1. dbus监控

    dbus-monitor

2. 查看dbus注册信息

dbus-send --session --print-reply --dest=org.freedesktop.DBus /com/routon org.freedesktop.DBus.ListNames

dbus-send --system --print-reply --dest=org.freedesktop.DBus /com/routon org.freedesktop.DBus.ListNames

3. 命令形式发送数据

dbus-send --session --type=signal --dest=com.routon.ble.s1701 /com/routon com.routon.Method.TnMessage string:'com.routon.VNET' uint32:'129' string:':1.27'
