Known problems

Hi,
I am trying to port Atmel's GuruxDLMSClientExample into MPLAB X IDE Using XC32 compiler. I am sending
uint8_t test_lnt_command[] = {0x7E,0xA0,0x07,0x03,0x21,0x93,0x0F,0x01,0x7E};
this through USART then I got reply from meter but when I call
"cl_init(&meterSettings, 1, 32, 1, DLMS_AUTHENTICATION_LOW, "lnt1", DLMS_INTERFACE_TYPE_HDLC);"
then debugger is stops at
"memset(settings->preEstablishedSystemTitle, 0, 8); "
Please help us to solve this problem.

Hi,

I believe that there is no space allocated for preEstablishedSystemTitle. You are not using malloc and you need to do it by yourself or use malloc.

Hello,
Could you please help me where to and how to add Malloc.

Kurumi

Hi,

You have defined this line:
DLMS_IGNORE_MALLOC

Just make sure that it's not defined and malloc is used.

Hi,

Is the message generated? Is the problem that the message is not sent with UART?

Hi,
I want to know that, Is there usart configuration/connection settings required in cl_init() function. Means I want to know is there any configuration to send data through USART.

Hi,

The stack will only generate and parse the bytes. You can send data as you need and you don't need to config UART for the stack.

Hello
Sir do you have Gurux code for SAME54 Xplained pro board to read all objects of meter ?
Please help us

Hi,

You can use the default library to read the data. The only thing you need to change is how you send and receive bytes from the serial port.

hello sir,
I can now send SNRM request got response from meter. When I send AARQ request I receive response that I can seen on Docklight but it controller receives only last 24 bytes of AARQ Response.

Hello,

I believe that your UART buffer is overridden. Check if that is the reason. Try to listen to UART events and handle data when it arrives

Hello,
Now I can Receives whole frame and process it. Now my AARQ Failed And closed connection.

Kurumi

Hi,

If your ARQ send fails, the reason might be the size of the UART buffer. Make sure that all data that you write to the buffer can fit it.

Hi,

Meter rejects the connection. Your password is empty. Check also client address. Not it's 32 (0x32).
