MSP430F67791: DLMS\COSEM. Error while restoring frames.

Aleksej

Part Number: MSP430F67791


Hello, the diagram shows the "state diagram of N (S) and N (R)".

Frame I(6.7) did not reach the client "7E A0 4E 41 03 FC 67 D6 E6 E7 00 C4 02 C0 FE",
So I command the RR (6) to request a repeat of the previous frame, in response I get,
RR (7) - readiness to receive the next frame, not the previous frame.

How to fix this error?

    Hello Aleksej,

    Unfortunately, I don't have much experience with the DLMS/COSEM library. I'm assuming that the client here is the MSP430F67791? Is the host/server a PC or something else? Are you able to debug your code to figure out why the frame did not reach the client (assuming it's the MSP430)? I'm assuming that the client lets the host/server know that the message was received. Do you know if there are multiple clients? I'm assuming this protocol is over UART, but please correct me if I'm wrong.

    The following resources may be helpful.

    Regards,

    Hello, James.

    As a client, I use my software, as a server - a stack from TI implemented in the MSP430F67791. I specially imitated the wrong frame, in order to work out the procedure for restoring frames when the connection is broken or an erroneous frame is received.

    After sending the command RR(6), I expected frame I(6,7) but in response received the command RR(7). The question is, why? Can I chat with the developers of the DLMS\COSEM stack?

    Hello Aleksej,

    Sorry for missing out this post!

    If your issue issue is still open, pls leave your email-id here so that I get in touch with you offline. As TI is no longer providing the DLMS library in the public domain, I will not be in a position to give you online support.


    Regards,

    Chander
