Hello, i am trying to read association logical name object but i get Not enough memory available error.

I am trying to do as your client example says to read one bye one, but i never leave com_readDataBlock() method and com_readDataBlock() returns out of memory error. Should I read only one data block, parse it, then again read?

Hi,

Your meter doesn't return all the bytes.
Some meters expect spesific frame size and if it's too small they can't handle it.
What meter you try to read?

BR,

My meter is: CL730S22. I have no problem to read association view with GXDLMSDirector, it should be possible with C also.

also, i wanted to ask a question:

cl_getObjectsRequest() method has hardcoded one OBIS:

static unsigned char ln[] = { 0, 0, 40, 0, 0, 0xFF };

1. Is this OBIS code is always the same for all meters?
2. What if i have another association logical name OBIS? Will it read everything that is available?
