Hi Sir, I need this information(frame type value and hcs and fcs) to convert wrapper to hdlc. Can you tell me how I should find these appropriate values?

Hello,

I have question regarding the DLMS.c master for Arduino IDE

1. Is there any documentation for the code what to be and not to be defined in the code or there's a setting to use serial port RS-232 because i need to connect my MCU to The smart meter using RS-232
2. Is it safe to directly connect MCU to RX TX GND of smart meter?

Thank you in advance.

Hello,

I´m connecting with AC6000 meter. Client address:0x01 Phy server:0x11 Logical address:0x01

Those are the frames:

Sending SNRM...
TX: 7E A0 08 02 23 03 93 3E 74 7E
RX: 7E A0 23 03 00 02 00 23 73 C0 48 81 80 14 05 02 00 80 06 02 00 80 07 04 00 00 00 01 08 04 00 00 00 01 CE 6A 7E

Server address bytes are: 00 02 00 23 ,is a 4 byte HDLC address.

Gurux Director is working properly, but when I try with C library I get DLMS_ERROR_CODE_FALSE with server address.

Any clue about how to solve this in C library?

Thank you.

Dear,

I successfully created a ProfileGeneric object (in http://www.gurux.fi/node/19730) and I can also read out the contents from the buffer and capture objects using the function below:

def read(self, ln, gp):
profile_generic = GXDLMSProfileGeneric(ln)
gp.reader.read(profile_generic, 3)
gp.reader.read(profile_generic, 2)
return profile_generic

pg = reader.read(ln, gp)

I can easily read the buffer contents with this read using pg.buffer.

Hello,

Is there a way to convert each gxObject (any type) attribute to string? There is a function int obj_toString(gxObject* object, char** buff) but it adds additional strings like "Index: 2 Value:" etc and I need only attribute strings.

Is there a function that returns single attribute to string something like this obj_attrToString(gxObject *object, int attributeIndex, char **buff) or it has to be newly written?
