mobilinkd on my linux laptop		2024-02-13T22:05:30+01:00	2024-02-16T17:08:08+0000	amateur-radio computerstuff	draft_post	true

Mobilinkd

I use blueman-manager, a graphical tool to manage bluetooth devices. Because I actually hate bluetooth and its unpredictability...

right click on to TNC4 Mobilinkd, Connect with: serial port

that will create /dev/rfcomm0

open that port with KISS

$ sudo kissattach /dev/rfcomm0 wl2k
AX.25 port wl2k bound to device ax0

For now, I haven't enabled auto-connect of the serial port.

We can now use this in pat http when we select AX.25+linux

There are a few files that need to be prepared.

/etc/ax25/axports

# /etc/ax25/axports
#
# The format of this file is:
#
# name callsign speed paclen window description
#

#1	OH2BNS-1	1200	255	2	144.675 MHz (1200  bps)
#2	OH2BNS-9	38400	255	7	TNOS/Linux  (38400 bps)
wl2k OE7DRT 1200 255 7 Winlink

and the pat config has

  "ax25_linux": {
    "port": "wl2k"
  },
  "serial-tnc": {
    "path": "/dev/rfcomm0",
    "serial_baud": 9600,
    "hbaud": 1200,
    "type": "Kenwood",
    "rig": ""
  },

Digirig

Using AX.25+agwpe in pat

  "ax25": {
    "engine": "linux",
    "rig": "",
    "beacon": {
      "every": 3600,
      "message": "Winlink P2P",
      "destination": "IDENT"
    }
  },
  "agwpe": {
    "addr": "127.0.0.1:8000",
    "radio_port": 0
  },
