Hello
I am using your Atmel code for ATSAME54 Xplained pro board. My code compiled and debugged it connected to meter
TX: 7E A0 07 03 41 93 5A 64 7E
RX: 7E A0 1E 41 03 73 8E 7F 81 80 12 05 01 80 06 01 80 07 04 00 00 00 01 08 04 00 00 00 01 53 3B 7E

but following code is not exicuting
gxClock clock;
ret = cosem_init(&clock.base, DLMS_OBJECT_TYPE_CLOCK, "0.0.1.0.0.255");

//Initialize connection.
ret = com_initializeConnection(&con);
if (ret != DLMS_ERROR_CODE_OK)
{
return ret;
}
Read clock.
ret = com_read(&con, &clock.base, 2);
if (ret != DLMS_ERROR_CODE_OK)
{
return ret;
}

When I run It I got Following Reply
TX: 7E A0 19 03 41 10 2A BF E6 E6 00 C0 01 81 00 08 00 00 01 00 00 FF 02 00 65 D7 7E
RX: 7E A0 10 41 03 30 53 A1 E6 E7 00 0E 01 03 02 94 A8 7E

Please help how to solve this problem.

Hi,

You don't call AARQ for some reason. Only SNRM is called. You need to check this.
Because the connection is not established the read fails.

HI,
Could you please help me how can I do this I am new to this dlms. Also it is possible please tell me flow of code. I dont understand how this instructions sent through UART.

Hi,

com_initializeConnection generates AARQ automatically. You need only send generated bytes as you have done with SNRM.

Check that parsing UA is not failed and your buffer is big enough to save generated AARQ message.

Hi,

Reading association view will return all the objects that the meter can offer in that association.

Hi,

Date-time is coming in octet-string and you need to convert it to gxtime. Then you can use time_toString2 to convert it to the string.
