Hello,

I am using Arduino code, DLMS C lib, Everything is works as expected, but on com_close() function it always return 258, instead of 0.

So, request to help in this matter.

Thank You

Hi,

Can you get the hex trace of what the meter is returning?
If you can't, try to read your meter with GXDLMSDirector and then get the log when you close the connection. Please, add only those last rows so I can check what the meter is returning.

I have tried a previous c library (don't know version, but 4 month ago), in this I didn't get this error with same meter, and also everything works ok.
And in guruxDirector also, doesn't face this type of error.

Hi,

There are no changes to this in ANSI C. I need the hex trace to solve this.
I can't solve this if I don't know what the meter is returning.
