Hi Sir,

I have read data from client to server in same PC. what i have change in com_readObject( ) function.

//Read object.
int com_readObject(
connection *connection,
gxObject* object,
unsigned char attributeOrdinal)
{
int ret;
message data;
gxReplyData reply;
mes_init(&data);
reply_init(&reply);
if ((ret = cl_read(&connection->settings, object, attributeOrdinal, &data)) != 0 ||
(ret = com_readDataBlock(connection, &data, &reply)) != 0 ||
(ret = cl_updateValue(&connection->settings, object, attributeOrdinal, &reply.dataValue)) != 0)
{
}
mes_clear(&data);
reply_clear(&reply);
return ret;

Hi shakti,

You don't change anything here. You need to change your communication parameters to access your meter. Parameters depend are you using TCP/IP or serial port connection.

Hi Sir,

You told me I have to change communication parameter . But which code I have change ( server or client ).

Thanks,

Hi,

You need to change TCP/IP address and port number. DLMS settings depend on the meter that you want to read. I strongly suggest that you use GXDLMSDirector to read your meter first and get an idea from DLMS meters.

Hi Sir,

I don't want to read meter. I want to just communicate between dlms server and client using TCP/IP connection in Linux. So what I have to do ???

Thanks,

Hi,

You can use client example. Give IP address and port number as a parameter. Like this.
GuruxDLMSClientExample -h YOUR_SERVER_IP_ADDRESS -p YOUR_SERVER_PORT_NUMBER
