KNX virtual crash when Write Command send about knx-go

[vapourismo]

You need to provide a little bit more information than that.

Do you use a router or tunnel client?
Can you provide a more detailed example?
Have you brought this up with the ‘knx-virtual’ project?
Does ‘knx-virtual’ log any information before crashing?

I have not experienced any KNX device (or any software for that matter) crashing when used with this library.

Thanks in advance. @vapourismo
Please let me know if you need any further information. I really appreciate your help.

Extra information:
I have setup HomeAssistant (https://www.home-assistant.io/) in IP 192.168.1.84 (Mac) and configured KNX Virtual. I am able to control the Switch without any issues.

I using Tunnel client
client, err := knx.NewGroupTunnel("192.168.1.21:3671", knx.DefaultTunnelConfig)

Can you provide a more detailed example?
Using KNX ETS i have setup a lamp and button with group "1/1/1". I am trying to control the switch using this package.
KNX Virtual installed in a separate windows box with IP 192.168.1.21.
Go/python code is running in mac with IP 192.168.1.84. They both are in the same network.

Have you brought this up with the ‘knx-virtual’ project?
Not yet. As this was working fine when used with Python and HomeAssistant.

Does ‘knx-virtual’ log any information before crashing?
No info before crashing but i found this in event log of windows.

Here i am attaching Go code and ETS5 sample knx project as zip file.

This seems like a KNX Virtual issue so far.

Can you provide network captures so we can look at the differences between xknx and this library?
Ideally something Wireshark-compatible.
