CPP Server Push Example - Push method shows NoAccess

Hi, thanks for the prompt reply.

I modified it like this

DLMS_METHOD_ACCESS_MODE CGXDLMSBase::GetMethodAccess(CGXDLMSValueEventArg* arg)
{
    // Methods are not allowed.
    if (arg->GetSettings()->GetAuthentication() == DLMS_AUTHENTICATION_NONE)
    {
        return DLMS_METHOD_ACCESS_MODE_NONE;
    }
    // Only clock and profile generic methods are allowed.
    if (arg->GetSettings()->GetAuthentication() == DLMS_AUTHENTICATION_LOW)
    {
        if (arg->GetTarget()->GetObjectType() == DLMS_OBJECT_TYPE_CLOCK ||
            arg->GetTarget()->GetObjectType() == DLMS_OBJECT_TYPE_PROFILE_GENERIC ||
            arg->GetTarget()->GetObjectType() == DLMS_OBJECT_TYPE_PUSH_SETUP)
       {
            return DLMS_METHOD_ACCESS_MODE_ACCESS;
        }
        return DLMS_METHOD_ACCESS_MODE_NONE;
    }
    return DLMS_METHOD_ACCESS_MODE_ACCESS;
}

It works properly. It shows "127.0.1.1:7000" as "Destination". From that I run Python DLMS Push Listener Example on port 7000 :

python3 Gurux.DLMS.Push.Listener.Example.python/main.py -p 7000

gurux_dlms version: 1.0.191
gurux_net version: 1.0.19
gurux_serial version: 1.0.21
TCP Server public-proxy-m20:7000

Now there are two things:

- "Failed to sent push. Reason: 258." I don't find anything related to error code 258. Why is that?
- I can't make the attribute to read/write, even though i write this code:

    pPush->SetAccess(3, DLMS_ACCESS_MODE_READ_WRITE);
    pPush->SetAccess(2, DLMS_ACCESS_MODE_READ_WRITE);
    pPush->SetAccess(4, DLMS_ACCESS_MODE_READ_WRITE);

Initially i want to be able to edit attribute 3 (send destination and method) so i can try this push on another computer running the Push Listener (just in case there's anything wrong with my computer's networking). Since it didn't work, i tried other attributes, but didn't work either. I don't think this has anything to do with GetMethodAccess, doesnt it?

Here's my complete push code, barely changed from the example code:

    //Add Push Setup object.
    CGXDLMSPushSetup* pPush = new CGXDLMSPushSetup();
    address += ":7000";
    // address = "10.10.1.3:7000"; // 2nd computer, different network, does not work
    pPush->SetDestination(address);
    GetItems().push_back(pPush);
    // Add push object itself. This is needed to tell structure of data to
    // the Push listener.
    pPush->GetPushObjectList().push_back(std::pair<CGXDLMSObject*, CGXDLMSCaptureObject>(pPush, CGXDLMSCaptureObject(2, 0)));
    //Add logical device name.
    pPush->GetPushObjectList().push_back(std::pair<CGXDLMSObject*, CGXDLMSCaptureObject>(ldn, CGXDLMSCaptureObject(2, 0)));
    // Add 0.0.25.1.0.255 Ch. 0 IPv4 setup IP address.
    pPush->GetPushObjectList().push_back(std::pair<CGXDLMSObject*, CGXDLMSCaptureObject>(pIp4, CGXDLMSCaptureObject(3, 0)));

    // get method acceess and set method access
    // std::cout << "pPush method access before set: " << pPush->GetMethodAccess(1) << std::endl;

    pPush->SetMethodAccess(0, DLMS_METHOD_ACCESS_MODE_ACCESS);
    pPush->SetMethodAccess(1, DLMS_METHOD_ACCESS_MODE_ACCESS);
    pPush->SetAccess(3, DLMS_ACCESS_MODE_READ_WRITE);
    pPush->SetAccess(2, DLMS_ACCESS_MODE_READ_WRITE);
    pPush->SetAccess(4, DLMS_ACCESS_MODE_READ_WRITE);
    // AddPushSetup(GetItems(), pRegister_curr, "0.8.25.9.0.255");

 

Thank you for the reply. I think the SendPush is called, because i write it like this:

	std::cout << "PreAction ln: " << ln << std::endl;
	if ((*it)->GetTarget()->GetObjectType() == DLMS_OBJECT_TYPE_PUSH_SETUP)
        {
            int ret = SendPush((CGXDLMSPushSetup*)(*it)->GetTarget());
            if (ret != 0)
            {
                std::cout << "failed to sent push. Reason: " << ret << std::endl;
            }
            (*it)->SetHandled(true);
        }

and it returned the 258 error code:

PreAction ln: 0.7.25.9.0.255
failed to sent push. Reason: 258

I tried running the python push listener on another computer, and change the IP address and port accordingly, for example i run it on my other computer with IP address 10.10.1.3 on port 7000. It gets stuck, and the server hangs. I also tried with more generic IP, 192.168.1.3 port 7000, but the result is the same. Here's the server debug output and the hex trace:

// server debug output
PreAction ln: 0.7.25.9.0.255


// hex trace
16:44:29 Method object 0.7.25.9.0.255, interface PushSetup

16:44:39 Data send failed. Try to resend 2/3 
16:44:44 Failed to receive reply from the device in given time. 

 It can't even response to any read request, be it register read, clock read, etc. If that happens, all i do is stop the program and re-run it. It eventually respond to request after the push process completed:

PreAction ln: 0.7.25.9.0.255
// wait x seconds, i haven't measured it
failed to sent push. Reason: 258

Oh yeah almost forgot, I use Low authentication

Regarding the GetMethodAccess, why should i add the code inside that block if the "Send Destination" is of an Attribute type (not Method type)? Do i need to set the Attribute access inside the GetMethodAccess?

Thank you
