BCU/Tpuart + Calimero = IP Router? about calimero-core HOT 6 CLOSED

v2.3 provides a link interface for TP-UART, see

Great. So accessing KNX via TP-UART would be possible.

I guess the existing IP Link implementation (tunneling+routing) can only interact with a real device and can not be used as a kind of "master" so that others can send data to this master, which can be then routed to the TP-UART link and vice versa?

I don't fully understand what you consider a real device.

Depending on the KNXnet/IP protocol requested to be used by the IP link, 1 endpoint (Tunneling) or [0..*] endpoints (Routing) are required. Client- and server-side of the protocols differ.

From your first question about a knx router interface, for calimero/eibd this means:
eibd uses the EIBnet/IP server front end, for which the equivalent in calimero is the KNXnet/IP server.
If you want to use the eibd front end for marshalling client data over a socket, you have to use eibd as this is specific to eibd.
How you multiplex data for transmission over a tpuart link is up to the application.

Seems we are using different wording. And I must admit, that I'm maybe not so familiar with the knx-conform-wording(, maybe also because I don't differentiate between knx and eib?!)

Question was: Is it possible to use an KNX TP-UART + Calimero + the computer's network-interface to "behave like an KNX IP Router device": Traffic from wired-knx-bus is routed to the ethernet (knx ip) and vice versa ??

From what I already understood:

The implementation to talk to the knx bus with an TP-UART is available. ok.

And the other end seems also to be present? --> "for which the equivalent in calimero is the KNXnet/IP server. "

Seems that all required part's are already there?
So, to put it all together:

Data from knx bus receives via TP-UART and the corresponding TP-UART link implementation in calimero. All I have to do is, forward the data (and maybe increment the routing counter and eventually some other stuff that real KNX IP Routers do) via the "KNXnet/IP server"(???) implementation to the ethernet and vice versa, right?

Yes, take a look at the readme of calimero-server. It does exactly what you want. Maybe a little ascii art helps:

                          |             calimero-server                |
                          |    server-side           KNX subnet side   |
client <-KNXnet/IP link-> | KNXnet/IP <--> gateway <--> [1..n] subnets | <-link-> KNX

All I have to do is, forward the data (and maybe increment the routing counter and eventually some other stuff that real KNX IP Routers do) via the "KNXnet/IP server"(???) implementation to the ethernet and vice versa, right?

This is the case if you only run the server-side parts of the KNXnet/IP protocol (as opposed to running a KNXnet/IP server). Then you have to implement all the rest that makes up an actual "server", i.e., the gateway logic, interface objects, subnet connection, message filtering, etc.

Thanks for the details.
