Xfbb interface with Linbpq

In bpq32.cfg add

TNCPORT
COMPORT=/home/pi/fbbded
TYPE=DED
STREAMS=10
APPLMASK=4
ENDPORT

This creates a DED Host mode TNC on device /home/pi/fbbded, accessible from the LinBPQ Node as Application 3. Change APPLMASK and APPLICATION line if you already use APPL 3

APPLICATION 3,FBB

This allows uses to connect to FBB. You can add the usual Call, Alias and Quality if you want to be able to access FBB directly instead of via the Node.

Change APPLMASK and APPLICATION line if you already use APPL 3

In /usr/local/etc/ax25/fbb/port.sys#

# FBB7.0.8-beta8

This tells fbb to use /home/pi/fbbded as a DED Mode TNC.

Installing Direwolf and LinBPQ on Raspian Stretch

Jeff KP3FT has written a nice document about the installation of Direwolf and Linbpq on a Raspberry with raspbian Stretch. Download the complet document here.

Dire Wolf

Installing Direwolf and linBPQ on a new Raspian Stretch installation.  It’s a combination from various websites and documentation, condensed down into a straightforward walkthrough.  This doesn’t include configuration of most BPQ settings, only enough to get it to use Direwolf as a modem.

Older Raspian versions like Jessie may require Pulse Audio removed first, prior to installing Direwolf.  Raspian Stretch by default does not have Pulse Audio installed.  My Raspian config settings have SSH and VNC enabled.

First:

After it restarts, install libasound:

Optionally install the following if you want to enable Direwolf to use the GPIO pin on certain USB sound devices for PTT:

Then install Direwolf (as of this writing, version 1.5 is the latest):

Plug your USB sound device(s) into the RPi, open a terminal, and run the following to verify the system sees the USB sound device(s).

If the Raspberry pi’s onboard audio is enabled, it will show up as Card 0, Device 0.  The USB sound device should show up as Card 1, Device 0.  A second USB sound device will show up as Card 2, Device 0, and so on.

Open the direwolf.conf file in a text-editor, scroll down, and enable the correct USB sound device by removing the # at the beginning of the appropriate line.  For example, on mine it is:

Scroll down and change “N0CALL” to your callsign in the line:

Enable the modem speed you want.  In my case, I enable 300-baud:

Scroll down and enable the appropriate PTT option for your setup.
Further down, enable and change the AGWPORT and KISSPORT settings for your setup.
Optionally disable all the APRS-related lines if you don’t want to use those functions.

Save the file and run Direwolf by double-clicking the desktop icon, or test-run it from Terminal with:

You should see packet activity if the radio is tuned on the right frequency and audio level is good.

Close Direwolf for now (CTRL-C) and install pilinBPQ (skip down to the Direwolf port section if pilinBPQ is already installed):

Copy an existing Linux bpq32.cfg from another source to /pi/linbpq. I have an old bpq32.cfg file here which would need some substantial editing for your own setup:

https://www.qsl.net/swlkp3/Packet/bpq32(Linux).cfg .

Be sure to rename it to bpq32.cfg .If you don’t use the above bpq32.cfg file, and add one or both of these Direwolf ports in the ports section of whatever copy of bpq32.cfg you have, depending on how many Direwolf modems you want to run.  Change the port numbers to whatever works with your particular setup.  The timing settings can also be changed; these are what worked with my setup for 300-baud HF packet and 1200-baud VHF packet.

Save the file.

Start Direwolf.

Open another Terminal and start linBPQ:

It should connect to Direwolf(s) on port 127.0.0.1:8001 or whatever port(s) you set up.

Notes:
——
Multiple instances of Direwolf can run at the same time.  Each instance has its own “.conf” file.  Each conf file needs to be edited to enable whatever port and USB sound device will be used.  To do that, just edit the original “direwolf.conf” file and save it under a new name, such as “direwolf_HF.conf”, etc.  Start each instance in Terminal using the “-c” switch to point Direwolf to the correct “.conf” file.  In my setup, I start the first Direwolf instance in Terminal with “direwolf -c direwolf.conf”.  The second instance is started in another Terminal with “direwolf -c direwolf_HF.conf”.

Direwolf has several options that can be used in the command line.  Three that I find particularly useful are the “-q”, -T”, and “-x” options.  By default, Direwolf shows audio in/out levels in its Terminal screen.  This can be turned off with “-q h”.  For example, when I run my HF 300-baud instance of Direwolf to disable audio reports, I run “direwolf -c direwolf_HF.conf -q h”

To show timestamps of sent and received packet frames, use the “-T” option with “%H:%M:%S”.  Example: “direwolf -c direwolf_HF.conf -q h -T %H:%M:%S” to disable audio reporting and show timestamds in hours-minutes-seconds format.

The “-x” option immediately starts Direwolf transmitting calibration tones, which I use mostly to key the transciever for tuning the antenna when I switch bands.  Example: “direwolf -c direwolf_HF.conf -q h -T %H:%M:%S -x”.  Enter CNTRL-C to stop the transmit.

The complete list of command-line options are in the Direwolf user guide, pages 126 through 128: https://github.com/wb2osz/direwolf/tree/master/doc

Fldigi and BPQ32

KP3FT post a example of how to setup FLdigi and BPQ32.

In the bpq.cfg driver settings, you will have to make changes for your own setup, but it does work.  For example, set the path to wherever your FLdigi executable is on your computer.  Also, set the default FLDigi mode to what you want.  In mine, the line “DEFAULTMODEM=PSK250R/1300” sets it to start FLDigi’s robust version of PSK-250 at 1300-hz waterfall frequency

Bpq32 Log options

John G8BPQ has made it possible to move the log dir of linbpq and pilinbpq. Nice

I’ve uploaded versions of linbpq and pilinbpq to my beta download site
that allow you to move the log directory. Start with a command line
parameter of logdir=directory, eg

../pilinbpq logdir=/dev/shm

 

You can download the new version here.

LinBPQ Applications Interface.

LinBPQ has a facility to make a tcp connection from the node to an application running on the same machine. This was originally intended to connect to a shell to enable basic configuration editing, but has been generalised to allow connects to other tcp ports, thus allowing you to write your own applications to be used with LinBPQ.

Ok, that sounds nice. Let give it a try.

Fist setup Linbpq, add de “cmdport” to the telnet port section.

I have add “CMDPORT 63000” but it can by any number.

Now add a Application at the end of de bpq32.cfg

Now we have to add some stuff to /etc/services and /etc/inetd.conf

/etc/services

/etc/inetd.conf

Now restart inetd. sudo killall -1 inetd

I have found a small script on the internet and make some adjustments.
This script is using some perl modules that has to be installed.

The testapp.pl script. /usr/local/linbpq/testapp.pl

Now we can run the script from linbpq. Let give it a try.

LinBPQ with Winmor port.

With the help of the config file of Jerry, N9LYA and some help from John, G8BPQ I have setup a Winmor port on my Linbpq.I use a Microham USB II as soundcard device connected to my Windows PC and a direct Cat kabel from my Linux PC to control the TRX.

Here is the section for the Winmor port. (BPQ32.CFG)

WINMOR TNC.ini

Winmor Status screen from Linbpq

Tnx for the help Jerry and John.

Complex BPQ32.cfg from N9LYA

N9LYA has setup a complex system using multi modes and multi ports. Using Packet 1k2 and 9k6, Hf Packet 300Baud, Robust packet, Winmor, Ardop, Pactor, Fldigi, Axip, Telnet.

DireWolf/Linpq with Systemd.

I have a bad time behind me, I have had a lot of arguments with Systemd to start DireWolf and Linpq when booting 🙂
If you like Systemd, you can read some about it here https://en.wikipedia.org/wiki/Systemd

I want Linbpq to run under /dev/tty2 and DireWolf under /dev/tty3. This is because if I login remotely I can view the monitor from DireWolf with “conspy”. “conspy 3” Hit esc a few times to leave conspy.

Systemd does not want to accept the start line with >/dev/tty3 &

This upper start line does not work.

So I had to come up with something else for that. So i wrote a start file. “direwolf.start”

Now i wrote a unit file to start DireWolf on boot.
/etc/systemd/system/direwolf.service

Now DireWolf is starting very nice on /dev/tty3

I had the same problem with Linbpq, which I solved in the same way.

Linbpq start file “runbpq”

The unit file “linbpq.service”

Ok, let’s see if it is running

Now have a look at /dev/tty2 “conspy 2”

 

SCS Tracker TNC and new BPQ32 Node

Sample config file based on a system off John, kx4o.

Jeff have made some comments about it.

 

SCS Tracker Driver for BPQ32 switch

SCSTracker.dll

This driver allows BPQ32 applications to make and receive Robust Packet or HF Packet calls using the SCS Tracker TNC. This driver is intended for using the Tracker on HF for forwarding, and only allows one connect at a time. For normal VHF operation or user access on HF, there is a separate driver, SCSTrackerMulti, that supports multiple connections (but not scanning).

Although the Tracker is an ax.25 controller, the driver only allows it to be used by one session at a time, so you must use the ATTACH command to allocate the port before making a call. So if your Tracker port is BPQ32 port 3, enter

ATTACH 3

Possible responses are:

#BPQ11:GM8BPQ-2} Ok

#BPQ11:GM8BPQ-2} Error – Invalid Port   // Port is not a Tracker port.

#BPQ11:GM8BPQ-2} Error – Port in use   // Port is in use.

Once attached to a port, you can issue commands to the TNC. These are the same as you would use to control the Tracker from a terminal, except that you don’t type an ESC before each command.

You can also select which mode a connect will be made in be entering HFPACKET or RPACKET. So to make a Robust call, enter

ATT 3
RPACKET
C CALLSIGN

For a normal (300 Baud HF Packet) call enter:

ATT 3
HFPACKET
C CALLSIGN

Configuration.

The driver configuration is specified in the bpq32.cfg file

The driver is defined to BPQ32 as an External port, and needs some driver-specific configuration

The first line of the config defines what BPQ Application incoming calls should connect to. If omitted, calls go to the command handler.

If you are using the Rig Control feature for scanning, add the RIGCONTROL command next.

If you want to listen for both normal and Robust packet connects, use the SWITCHMODES n command. This specifes how long to spend in each mode. Note Rigcontrol will override this.

If you want users to be able to connect to any of your applications, use the USEAPPLCALLS command.

If you want the controller to start in Robust mode, and return to that mode after a connect, use DEFAULT ROBUST

All commands that are essential to run with BPQ32 are sent automatically. You only need to include any special setup you need.

The commands that are preset are in two groups. One set is sent before the commands you specify, so can be changed. The others are sent after your commands, as they are essential for correct operation with BPQ32.

Sent before your config

Sent after your config

MYCALL is set to the PORT config PORTCALL if specified, otherwise to NODECALL. Any MYCALL in the config file is ignored.

Other possible configuraton parameters are:

FORCE ROBUST
Only use Robust Packet. Disable any switch to Normal Packet

WL2KREPORT
send Frequency info to the WINLINK database. See here for details.

UPDATEMAP
The modem logs connects to the Nodemap if you have specified a LOCATOR in your BPQ32.cfg. If you specify UPDATEMAP, stations heard will also be sent to the map.

BEACONAFTERSESSION
Send Beacon after each session
