Good morning,
I have java DLMS server running on NetBeans. In the code I have put listen to the COM4 serial port.
class Settings {
public TraceLevel trace = TraceLevel.INFO;
public int port = 4060;
public String serial = "COM4" ;
public boolean useLogicalNameReferencing = true;
}
Then I have the DLMS client in C in a virtual machine (virtualBox),listening to the COM1 serial port (/dev/ttyS0 on Ubuntu).
COM1 and COM4 serial ports are virtually connected.
I run the client with the command,
sudo ./bin/gurux.dlms.client.bin -S /dev/ttyS0
or
sudo ./bin/gurux.dlms.client.bin -S /dev/ttyS0 -c 16 -s 1
and each time it gives me different things:
GetAssociationView
GetObjects failed Send failed.
Close failed.Error. 252
SNRMRequest failed Send failed.
Error. 252
AARQRequest failed Send failed.
Close failed.Error. 252
Could you help me?
Thanks you.
Hi,
Hi,
Check first that you can operate with the serial port.
Then give "-t Verbose" parameter for the server and the client. Check what bytes you are receiving and sending.

Hi,
Hi,
The server receives different things every time, these are some examples:
1.-
Client: sudo ./bin/gurux.dlms.client.bin -S /dev/ttyS0 -t Verbose
InitializeConnection
TX: 7E A0 07 03 21 93 0F 01 7E
SNRMRequest failed Send failed.
Error. 252
Server: run:
Logical Name DLMS Server in serial port COM4
----------------------------------------------------------
Press Enter to close.

2.-
Client: TX: 7E A0 07 03 21 93 0F 01 7E
SNRMRequest failed Send failed.
Error. 252
Server: RX: 7E A0 07 03 21 93
It seems that the server does not receive the complete frame that the client sends
This occurs by running the client only once, but if I run the client 2 times in a row this happens:
first run
client: InitializeConnection
TX: 7E A0 07 03 21 93 0F 01 7E
SNRMRequest failed Send failed.
Error. 252
Server : RX: 7E A0 07 03 21 93 0F 01
second run
client: InitializeConnection

With the gurux director, if it works well, I don't understand.
Thanks you.
Hi,
Hi,
Can you run ANSI C in Windows and check if it works from there? I checked this with my Windows and Linux, and it worked without problems. What Ubuntu version you are using?
BR,
Mikko
Hi,
Hi,
Sorry for my ignorance, but I don't know how to run ANSI C in Windows, could you tell me how?
The Ubuntu version I use is:
Distributor ID: Ubuntu
Description: Ubuntu 18.04.3 LTS
Release: 18.04
The server uses a baud rate of 9600, the client with the command dmesg | grep tty, it tells me this:
[ 0.004000] console [tty0] enabled
[ 2.167286] 00:02: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A
but I have changed the baud rate to 9600 with the command:
setserial -v / dev / ttyS0 baud_base 9600
with the command: setserial -a / dev / ttyS0
gives me this:
/dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4
Baud_base: 9600, close_delay: 50, divisor: 0
closing_wait: 3000
Flags: spd_normal skip_test
but with the previous command: dmesg | grep tty, it gives me the same as before
[ 0.004000] console [tty0] enabled
[ 2.167286] 00:02: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A
Hi,
Hi,
You need to use Visual Studio to build it and then you can run GuruxDLMSClientExample in the same way as in Linux.
You don't need set the serial port settings because the client app don't use tty. It communicates directly with the serial port. Default serial port settings are 9600 8None1.
BR,
Mikko
It is the first time that I
I just opened and compiled the project with visual studio. I have run it through the windows command line and the first time it said: GetObjects failed Send failed.
But all the other times it has worked correctly.
I must have some problem with VirtualBox or the ubuntu version.
Do you know why it could be?
Thank you very much for your help
Hi,
Hi,
Try to start server and client in Windows first. The reason is usually in serial port settings, but it's strange if you can make the connection and it stops answering when you read association view.
