Gurux DLMS for Java

Hi Mikko,

We can change byte[] date to GXDateTime using GXDLMSClient.changeType for certain OBIS Ids like(0.0.0.1.2.255)
Ex.
GXDLMSClient.changeType((byte[]) dt, DataType.DATETIME)

But How to do reverse? If I have to change a GXDateTime Object to 12 byte size byte[].

We need this for passive relay time, 4th parameter OctetString.

<Array>
<Structure>
<UInt32 Value="300" />
<UInt32 Value="1800" />
<UInt32 Value="5" />
<OctetString Value="07 FF FF FF FF FF FF 00 FF 80 00 00" />
</Structure>
</Array>

Thanks in Advance.

Hi,

You can write this like this:

GXArray arr = new GXArray();
GXStructure structure = new GXStructure();
arr.add(structure);
structure.add(new GXUInt32(300));
structure.add(new GXUInt32(1800));
structure.add(new GXUInt32(5));
structure.add(new GXDateTimeOS(Calendar.getInstance().getTime()));
GXDLMSData obj = new GXDLMSData(YOUR_OBIS_CODE);
obj.setValue(arr);
GXByteBuffer bb = new GXByteBuffer();

dlms.write(obj, 2);

BR,
Mikko
