C7 - METHOD_RESPONSE
02 - RequestType
81 - InvokeId
00 - Is not last block
00 00 00 01 - BlockIndex
00 - Status
82 - count < 0x10000

00 - Status - the code that this 0 adds
GXDLMS.cpp CGXDLMS::GetLNPdu
// Add status if reply.
if (p.GetStatus() != 0xFF)

Hi !

Whether this status is necessary or not - I don't know.
I see a problem in receiving the second block.
The client (not Gurux) receives the first block and requests the second block.
7E A0 14 02 11 61 DE 5C 4B E6 E6 00 C3 02 81 00 00 00 01 1D D7 7E

But Gurux responds in the negative 97 - frame rejection.
7E A0 08 61 02 11 97 F5 71 7E

See the last two lines of the dump.

Pardon me.
I asked the question badly.
I need to explain to you.

Need to transfer the response (METHOD_RESPONSE) using GURUX.CPP.
I replaced in GXDLMS.cpp CGXDLMS::GetLNPdu
as in the comment // Change request type If get response and multiple blocks is needed.
if (p.GetCommand() == DLMS_COMMAND_GET_RESPONSE )
by
if (p.GetCommand() == DLMS_COMMAND_GET_RESPONSE || p.GetCommand() == DLMS_COMMAND_METHOD_RESPONSE )

GURUX successfully generates and transmits (odd lines) C7 METHOD_RESPONSE
and receives answers (even lines).
See the dump in the post above.

The first block is successfully transmitted.
And the second block is not transmitted.
The client (not Gurux) receives the first block.
7E A0 14 02 11 61 DE 5C 4B E6 E6 00 C3 02 81 00 00 00 01 1D D7 7E

GURUX responds in the negative 97 - frame rejection.
7E A0 08 61 02 11 97 F5 71 7E

This is the problem.
How to fix the code so that GURUX would pass the second block?

I replaced in GXDLMS.cpp CGXDLMS::GetLNPdu
as in the comment // Change Request type if Set request and multiple blocks is needed.
if( p.GetCommand() == DLMS_COMMAND_SET_REQUEST )
by
if( p.GetCommand() == DLMS_COMMAND_SET_REQUEST || p.GetCommand() == DLMS_COMMAND_METHOD_REQUEST )

But this is not enough.

Hi.
I have compared the requests DLMS_COMMAND_GET_REQUEST and DLMS_COMMAND_METHOD_REQUEST.

7E A0 14 02 11 61 DE 5C 4B E6 E6 00 C3 02 81 00 00 00 01 1D D7 7E
C3 - METHOD_REQUEST
02 - DLMS_GET_COMMAND_TYPE_NEXT_DATA_BLOCK
81
00 00 00 01
1D D7 7E

The function CGXDLMSLNCommandHandler::HandleMethodRequest
does not handle the type DLMS_GET_COMMAND_TYPE_NEXT_DATA_BLOCK.
Reads Attribute ID as for the type DLMS_GET_COMMAND_TYPE_NORMAL.
Here is the error code DLMS_ERROR_CODE_OUTOFMEMORY.
And forming a response DLMS_COMMAND_UNACCEPTABLE_FRAME.
7E A0 08 61 02 11 97 F5 71 7E

To handle the type DLMS_GET_COMMAND_TYPE_NEXT_DATA_BLOCK
correctly you need to change the function CGXDLMSLNCommandHandler::HandleMethodRequest
like the function CGXDLMSLNCommandHandler::HandleGetRequest.

Hi.

Can I get a test version of the library ?

Hi.
Unfortunately, this new functionality is not added to the examples:
GuruxDLMSServerExample and GuruxDLMSClientExample.
For use, I need a simple example.
Do you have examples?
