获取设备配置

Platform=>>Device: 平台端可以通过ehome协议主动请求当前设备配置信息:

<?xml version="1.0" encoding="GB2312" ?>
<PPVSPMessage>
    <Version>2.5</Version>
    <Sequence>3564</Sequence>
    <CommandType>REQUEST</CommandType>
    <Method>PARAM</Method>
    <Command>GETDEVICECONFIG</Command>
    <Params>
        <ConfigCmd>GetServerInfo</ConfigCmd>
        <ConfigParam1>0</ConfigParam1>
        <ConfigParam2>0</ConfigParam2>
        <ConfigParam3>0</ConfigParam3>
        <ConfigParam4>0</ConfigParam4>
    </Params>
</PPVSPMessage>

Device =>>Platform: 设备回复当前基础信息:

<?xml version="1.0" encoding="GB2312"?>
<PPVSPMessage>
    <Version>2.0</Version>
    <Sequence>3564</Sequence>
    <CommandType>RESPONSE</CommandType>

            </SERVERINFO>
        </ConfigXML>
    </Params>
</PPVSPMessage>

心跳保活

Device=>>Platform: 设备与平台之前通过心跳来定时进行保活。

<?xml version="1.0" encoding="GB2312"?>
<PPVSPMessage>
    <Version>2.0</Version>
    <Sequence>21911</Sequence>
    <CommandType>REQUEST</CommandType>
    <Command>KEEPALIVE</Command>
    <Params>
        <DeviceID>560796072</DeviceID>
    </Params>
</PPVSPMessage>

Platform=>>Device: 平台在收到保活请求后进行回复。

<?xml version="1.0" encoding="GB2312" ?>
<PPVSPMessage>
    <Version>2.5</Version>
    <Sequence>21911</Sequence>
    <CommandType>RESPONSE</CommandType>
    <Method>CONTROL</Method>
    <WhichCommand>KEEPALIVE</WhichCommand>
    <Status>200</Status>
