Re: Direwolf as a TNC Help
Danny, thank you for the reply.
There is a way to find the device, yes
Basically instead of using /dev/ttyUSB0 or 1 I'm targeting it by ID by using /dev/serial/by-id/............
I had not however tried /dev/ttyUSB* but just gave it a go and the results were the same. /dev/ttyUSB1 DTR gave a dead key
I am however going to give creating a link to each device a go so they are better sorted as found here () starting at 8:39.
Something I didn't realize you could do until I saw that.
Basically once I figure out exactly what is what I'm going to at least create a /dev/300PTT and a /dev/857PTT link with rules so that no matter how or when the system starts I will always know exactly where and what my /dev/PTT is.
I'm about 90% sure /dev/USB1 and /dev/serial/by-id/usb-Silicon_Labs_CP2105_Dual_USB_to_UART_Bridge_Controller_00F8CEC3-if01-port0 is CAT/PTT control and I believe the problem is that PTT is controlled by CAT and not just a simple RTS DTR command.
The question is how to work with and/or around a CAT command for something so new that it's not listed in any libraries yet?
On the SCU-17 you have two devices per SCU-17. One is CAT control the other is a sound interface.
For instance I have /dev/ttyUSB0, /dev/ttyUSB1, /dev/ttyUSB2 and /dev/ttyUSB3 as I have two SCU-17's connected.
ls /dev/serial/by-id/ lists them as the following...
usb-Silicon_Labs_CP2105_Dual_USB_to_UART_Bridge_Controller_00AC0110-if00-port0
usb-Silicon_Labs_CP2105_Dual_USB_to_UART_Bridge_Controller_00AC0110-if01-port0
usb-Silicon_Labs_CP2105_Dual_USB_to_UART_Bridge_Controller_00F8CEC3-if00-port0
usb-Silicon_Labs_CP2105_Dual_USB_to_UART_Bridge_Controller_00F8CEC3-if01-port0
The other SCU-17 is connected to a 857D and that is listed in hamlib, well the 857 is, not the 857D specifically though the commands should be the same.
FLRig has absolutely no problem controlling the 857D so for FLDigi, WSJTX and JS8Call I just point them to FLRig for control and it works great, plus it allows me control of my rig on my screen, pretty much just bling there but hey, whatever, could come in handy for remote stuff.
Anyhow, indeed a good thought about using another app to control it, it does have me thinking about other ways to achieve the same objective though not certain how at the moment.

Re: Direwolf as a TNC Help
Patrick,
The following is the entire contents of my direwolf.conf running on a Raspberry pi.
ADEVICE plughw:1,0 plughw:1,0 ACHANNELS 1 CHANNEL 0 MYCALL K5CG MODEM 1200 PTT /dev/ttyUSB0 RTS TXDELAY 30 TXTAIL 10 AGWPORT 8000
The serial port is an FTDI USB to RS-232 cable and the radio (a KW TM-V71A) is set to key on the assertion of RTS (using it's Echolink Sysop mode feature). This appears as /dev/ttyUSB0.
Audio in/out is via a simple USB sound fob. This appears as device #1.
YAAC connects to the AGWPORT and direwolf keys the radio when needed.
I don't know anything about the SCU-17 but is there a way to know the COM port number or device name from whatever PC you are connecting it to?

Anyone have an insite on how to get PTT working or some things I can test to get it working?
I've tried ending the first un-commented PTT line with RTS, RTS DTR, RTS -DTR, -DTR and DTR and it will dead key
Being that hamlib doesn't have any of the D (digital) variations in it's library I tried RIG 1021, RIG 1022 and RIG 1043, none of those seemed to work either.
I do know my com port is set to 19200, I set it, Data speed is set to 1200, so I know that is set correctly but I'm not sure what other options I have regarding PTT configuration.
Does anyone have any ideas, thoughts and or suggestions?
I'm willing to give whatever you think up a go to see if we can get the SCU-17 to key PTT

Re: Direwolf as a TNC Help
I'll jump over there and see what I can get figured out. I have the radio connected via USB to a via a ?which provides CAT control via a serial port and sound via a 10-pin mini-DIN to 6-pin Mini-DIN. The 6 pin is plugged into the I am able to see Direwolf decode what the radio receives, now I need to get PTT working to verify I have the correct outgoing or microphone port.

Rob is right here (sorry for the confusion).? I did
have them reversed BUT it's the "DATA IN" signal that also needs
the ability to enable or disable the application of pre-emphasis
if your radio supports this.? For say Kenwood v71/d710 models,
here is a thread about it:
?? /g/VARA-MODEM/topic/74742391
Ultimately, when in doubt, assume your radio is applying the
emphasis / de-emphasis to your signal which is the CORRECT choice
for 1200bps packet used with APRS, classic connected packet, etc.

Re: Direwolf as a TNC Help
Hello Patrick,
OK, I seemingly overlooked the volume on the sound
interface and have confirmed direwolf sees traffic but YAAK isn't,
not sure why since YAAK does report a connected application on
port 8001 when I open it.
I cannot help you with YACC APRS application running over Java but I
would assume you have a configuration issue with that application.?
Consider joining the YACC support group at [email protected] but
beyond that, try enabling debugging on YACC and see what that might
tell you.
Just got PTT kind of working but it will dead key with either
PTT line I use when direwolf is run.
How have you connected your sound device to your radio?? Is it via a
specific serial port's control signal?? Maybe you're using GPIO pins
on the sound device, GPIO pins on a Raspberry Pi?? Maybe you're
using a Signalink with "auto-VOX"?? Are you using something like an
easy-digi isolation device?

Re: Direwolf as a TNC Help
OK, so yea, going to need some help. I'm finding it a bit overwhelming. Direwolf is capable of doing quite a bit considering.
The biggest issue I'm having right now is trying to target the correct sound device.
Here is my list of sound devices...
**** List of PLAYBACK Hardware Devices ****
card 0: Generic_1 [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
? Subdevices: 1/1
? Subdevice #0: subdevice #0

? Subdevice #0: subdevice #0
card 3: CODEC_1 [USB Audio CODEC], device 0: USB Audio [USB Audio]
? Subdevices: 1/1
? Subdevice #0: subdevice #0
In Direwolf I set the sound (AChannels) as follows...
ACHANNELS 1
ARATE 44100
ADEVICE plughw:CARD=CODEC_1,DEV=0 hw:CARD=CODEC_1,DEV=0
DWAIT 0
SLOTTIME 10
PERSIST 63
TXDELAY 30
TXTAIL 10
FULLDUP OFF
The extra parameters weren't in the config file, I assumed likely the default anyhow but for future reference and to be sure, I put them in to be set.
It's likely they're not in the right spot, but anyhow....
I targetted what I believe is the correct sound device but I'm not seeing any decode nor PTT
I'm transmitting from my APRS iGate (connected over the network via KISS from my desktop) but it doesn't look like the 300DR received it though I can hear the 300DR heard the traffic.
When I run direwolf and then open YAAC I get the following.......
Dire Wolf DEVELOPMENT version 1.7 E (Apr 25 2022)
Includes optional support for:? gpsd hamlib cm108-ptt
Reading config file direwolf.conf

KISS protocol set hardware "MODEML:", chan 0
KISS Set Hardware unrecognized command: MODEML.

KISS Set Hardware unrecognized command: MODEMBW.
Direwolf has to point directly to the device and not depend on Pulse or ALSA to determine the inputs and output or there's no way I can use two radios at the same time on one machine.
Keep in mind the 300DR is on a dummy load, all it can hear is my iGate and if it transmits I'm sure only the iGate will hear it.
PTT is configured as follows....
PTT /dev/serial/by-id/usb-Silicon_Labs_CP2105_Dual_USB_to_UART_Bridge_Controller_00F8CEC3-if00-port0 -DTR
#PTT RIG 1021 /dev/serial/by-id/usb-Silicon_Labs_CP2105_Dual_USB_to_UART_Bridge_Controller_00F8CEC3-if00-port0 19200
I have the other PTT there as I was testing with it, there was no PTT with either
Other config settings I have is....
CHANNEL 0
MY CALL KD7WPQ
MODEM 1200
AGWPORT 8000
KISSPORT 8001
FIX_BITS 1
Everything else in the config file is all commented (#) out

d'oh.? This was originally supposed to appear under the 'Headaches with direwolf + linpac ' topic.? Look there for context.

Based on suggestions, I tried to follow using the direwolf calibration tones(-x).
For my test setup I have a C-Media USB Audio attached to a yaesu ft-817, and a kenwood tr-2500 or kenwood tm-241 connected to a ASUS Xonar U7 MKII back to the same computer to monitor how the signal looks over the air.? Note that I also ran two instances of direwolf, and I was able to communicate between them, but I have still had no luck talking to other stations.

Re: Direwolf as a TNC Help
Thank you for the reply.
I've given that a go before though I may have missed what I was looking for and I don't think I realized it was the official Direwolf howto guide so let me give it a go again and see what I can get done and get back to you.
Regarding operating on the FT857 while operating VHF APRS it's very likely I'll have something like JS8Call or WSJTX or FLDigi going on the FT857 while the 300DR is doing APRS.
Basically they'll be handled by different applications at the same time though I'd like to be able to switch it up when and if needed.
Such as putting it in a APRS bridge or something of the sort. Bridging VHF to HF such as in the situation of being unattended for any reason there by allowing a local station to reach far away stations and visa versa while off the grid.
This would be a just in case situation
Being able to have a application like YAAC monitor, send and receive messages at the same time would be handy as well with both.
Basically it's a contingency plan, just in case.
For now I'll start with just the 300DR, make a backup of the config then try other options.
Baby steps, get it working then go from there.
I'll report back if I start racking my brain against the wall.

A friend of mine and I are getting more and more into APRS.
We love the messaging and optional tracking/Txing location features.
We plan to use it for off the grid stuff such as hiking, search and rescue (if it ever comes up), notifying loved ones of our location when out in the back country, ect
Currently I have Direwolf running on a Raspberry Pi4 with a generic USB sound fob modified to trigger PTT when audio output is detected.
It acts strictly as a iGate for the area
I am currently working on getting it working with two radios in my some what go-box. I say somewhat because it's heavy but it's meant to act as a portable control station.
GigaIPC QBIX Pro AMD Ryzen V1605B Indestrial Embedded Fanless PC

Yeasu FTM-300DR (For digital and quick basic APRS)
Primary software I use...
YAAC
Xastir
Direwolf
FLDigi
FLRig
WSJTX
JS8Call
And many more as I didn't want it and not have it when in the field though they may not all be configured. I also download and hold documentation just in case it's needed.
I have other upcoming projects which include using a couple ODroid N2+'s for mobile use (Linux, likely 32bit, hopefully 64bit).
The primary reason to use a portable low power PC is for the extra control, logging, messaging and mapping features.
I prefer using linux as it's open source, updates don't require waiting a half hour to use your machine again, more secure than Windows and more stable than Windows (in my opinion)
Sure you can't find everything you want in Linux you can in Windows without some extra work but I find the extra work rewarding and helps me understand my system better.
A friend of mine uses the Tiny Tracks and Raspberry Pis (32bit Linux)
When you get the AX25 how to working I would be EXTREMELY interested in reading it and giving it a go.
I find configuring AX25 a little overwhelming at the moment. I've done some reading on it but can't quite wrap my head around it.
I understand each dev needs a assigned call with SSID and each call with SSID needs a IP, or at least I think I understand but how to go about doing all that is a bit mind numbing
I understand networking, routing, subnetting and what have you but to assign that much to a device, wow. I'm sure there's reasons for it but that's currently beyond me at the moment.
Hopefully what I listed here is helpful. If you want to know more feel free to ask.

I have experimented with Raspberry Pi4 (Linux) where I installed APRS32 and DW, using the SignalinkUSB to connect to radio. I have yet to figure out how DW recognizes the comm ports. Seems RPi with DW is perfect for long running sessions of APRS32. Small size, less power, etc.

Hello J K,
It's unclear if Direwolf's support can be expanded to support more
sound devices but I bet the hard work is in the *test* of this
change.? I really doubt many people would need such a thing.? Why??
A single instance of Direwolf can support up to three stereo sound
devices ultimately supporting up to SIX different radios (one radio
on the left channel, another radio on the right channel).? That
said, there are limitations with this setup such as Direwolf cannot
interdependently transmit (aka asynchronously) send to all it's
channels.? It has to do this sequentially going from channel 0 all
the way through channel 5.? This isn't to much of a problem for
almost all installations but it's something to consider.
If you really need more active Direwolf channels, you can simply
start up a second, third, etc instance of the Direwolf binary
specifying different direwolf configuration files.? As long as the
different direwolf configuration files specify different sound
devices, you should be good.? The main limitation of this approach
is that you won't be able to interconnect the different packet
channels together for say digipeating, etc.?
Curious, what is your specific need to support more than six radios
per instance of Direwolf?
