Unable to read Invocation Counter(0.0.43.1.2.255).

Hi Mikko,

Thanks a lot for reply.

I am able to connect the smart meter using DLMS Director tool. I have attached a screenshot of tool herewith. But I am unable to connect using C++ example application. I have filled the connection variable as mentioned below. The socket connection is succeeded but when read invocation counter inside the "comm.InitializeConnection()" method is get hanged. Please find the trace log as well-

Kindly guide me how should I fill the connection parameter for the same.

Hi Mikko,

Thanks for reply.

I had also tried earlier as you said but I was unable to read and update "Invocation Counter". I have changed the method from "SetHexString" to "AddString" as I mentioned below-

Anything else which I should mention. Please suggest.

/////////// Code /////////////////
if (systemTitle != NULL)
{
bb.Clear();
bb.AddString(systemTitle);
cl.GetCiphering()->SetSystemTitle(bb);
}
if (authenticationKey != NULL)
{
bb.Clear();
bb.AddString(authenticationKey);
cl.GetCiphering()->SetAuthenticationKey(bb);
}
if (blockCipherKey != NULL)
{
bb.Clear();
bb.AddString(blockCipherKey);
cl.GetCiphering()->SetBlockCipherKey(bb);
}

Hi,

I have checked with the client example. I am facing same problem "inside the UpdateFrameCounter() method and hanged when read invocation counter".

Kindly find the trace content.

HI Mikko,

Thanks for reply.

Even, I have tried with "GuruxDLMSClientExample.exe" application with the fallowing argument list "-h 9522:0122:4022:24bb:0000:0000:0000:0002 -p 4059 -i WRAPPER -c 32 -a XXXX -P lnt1 -C AuthenticationEncryption -T XXXXXXXXXX -A XXXXXXXXXX -B XXXXXXXXXX -v 0.0.43.1.2.255 -I -t Verbose". The socket connection is succeeded but it freezes when read the invocation counter at this method "if ((ret = Read(&d, 2, str)) == 0)" under the UpdateFrameCounter() method of the InitializeConnection() method.

I am sharing the code snippet where it freezes-

//------------------ part of GuruxDLMSClientExample ---------------
std::string ln;
ln.append(m_InvocationCounter);
CGXDLMSData d(ln);
std::string str;
if ((ret = Read(&d, 2, str)) == 0) // NOTE: at this point it freezes.
{
m_Parser->GetCiphering()->SetInvocationCounter(1 +
d.GetValue().ToInteger());
}
printf("Invocation counter: %li\n", m_Parser->GetCiphering()->GetInvocationCounter());
reply.Clear();
Disconnect();
//----------------------------------------

I have tried with same parameter through DLMSDirector tool. It connects to the meter and able to get association view as well. Even, I can read the desired object.

I am sharing the TRACE log of the "GuruxDLMSClientExample"-

I am using latest version of "GuruxDLMSClientExample". I am using same example for IPv4 and IPv6. There is no any differences there?
Please suggest the solution. I have been trying for a long.

I have shared the smart meter details through email. Kindly check and revert about the issue.
