HOWTO: Link XRouter (XrPi, XrLin, XrWin) With BPQ
(On the same computer, or across the network)
The best way to do this is via the AXUDP (AX25 over UDP/IP) protocol.
On the Same Computer:
When both nodes are on the same computer, they can be linked via the operating system's “loopback” interface, usually known as “localhost”.
If we assume that GB7XRP is the XRPi node and GB7BPQ is the BPQ node:
In BPQ.CFG…
UDP 10093 MAP GB7XRP localhost 9393 B
In the above example, 10093 is the UDP port that BPQ RECEIVES on, and 9393 is the UDP port that BPQ TRANSMITS on to GB7XRP (they are shown as different numbers to avoid confusion, but could be the same).
In XROUTER.CFG…
You need two things: (a) an AXUDP INTERFACE, and (b) a PORT “attached” to that interface..
INTERFACE=1 ID=AXUDP TYPE=AXUDP MTU=256 ENDINTERFACE
If you already have an AXUDP interface, you will only need the **PORT* because the interface will support unlimited ports.
