I am trying to connect using CPP sample to Indian meter from Crystal manufacturer,
I am able to successfully connect and read data with Low authentication,
also I am able to successfully connect with High auth from Director application,
but High authentication fails with CPP sample tool:
./gurux.dlms.client.bin -h 192.168.0.14 -p3333 -w -c 48 -s 1 -a High -Paaaaaaaaaaaaaaaa
InitializeConnection

Looks like authentication requests differ in logs above
Source code in GuruxDLMSClientExample.cpp was modified in order to enable encryption,
these lines were added:
CGXDLMSSecureClient cl(useLogicalNameReferencing, clientAddress, serverAddress, authentication, password, interfaceType);
> CGXByteBuffer title;
> CGXByteBuffer key;
>
> title.Set("GRX12345", strlen("GRX12345"));
> key.Set("AAAAAAAAAAAAAAAA", strlen("AAAAAAAAAAAAAAAA"));
> cl.GetCiphering()->SetSystemTitle(title);
> cl.GetCiphering()->SetSecurity(DLMS_SECURITY_ENCRYPTION);
> if (authentication == DLMS_AUTHENTICATION_HIGH)
> cl.GetCiphering()->SetSecurity(DLMS_SECURITY_AUTHENTICATION_ENCRYPTION);
> cl.GetCiphering()->SetBlockCipherKey(key);
> cl.GetCiphering()->SetAuthenticationKey(key);
Gurux.DLMS.cpp, unable to set up High authentication with Crysta
Hi,
It's hard to say what is the problem because messages are encrypted. Check your keys that they are correct. That is usually the reason.
