Re: Repeating "GPSD: Location fix is now 2D/3D"
A lot of conversation about the PPS. I am pretty sure ths conversation was about getting position infomration through gpsd, not time (beyond the data stamp). I have no idea how a Garmin GLO2 could implement a PPS - its Bluetooth. Is this just additional commentary for tose using gpsd for more than position? ? I don't see anything on PPS in the Direwolf manual.? I am not sure how Direwolf benefits from a PPS? Not trying to be critical, just checking if I missed something. Robert Giuliano KB8RCO

Hi Fred,

Both my Ublox devices - LEA4 (IIRC) and a considerably newer M8 - have 1PPS so yours likely does too. The Garmin I dabbled with was the 18-5Hz with sentences sent five times per second for better positional accuracy but its PPS seemed to not play nicely with gpsd. Either that or I wasn't smart enough to make it happen! I cut my losses and bought the M8 board for the RPi4 for my Stratum 1 network time server. Take care Regards Ray vk2tv On 7/10/21 3:33 am, Fred Hillhouse wrote:

Re: rPi 4 / Signalink USB / Yaesu ft-895 / Direwolf.
Nick
Thanks David. Are you by chance on Discord?? I'd love to chat about options. I'm not trying to get the KPC back into the stack. I just want the rPI to run direwolf and then find a good client that I can hit from on the LAN. My primary use case is to use commands like? C EOCND?- to hop from node to node in our Marin Country packet network, and open corresponding MBs (mailboxes - these are usually hosted on old school TNCs) I also want to be able to access the Digipeater on ISS. I can see the traffic when it goes overhead, but no way to upload. I'm going to be on this google Meet video chat for ten minutes in case you care to help out "in person" On Mon, Oct 4, 2021 at 1:35 PM David Ranch <direwolf-groupsio@...> wrote:

Re: rPi 4 / Signalink USB / Yaesu ft-895 / Direwolf.
开云体育Hello Nick, I have a KPC3+ in the garage.? You can definitely access Direwolf via port 8000 and 8001 for AX.25 services but a KPC3 cannot do this alone.? There are ways to integrate a KPC3+ with Linux and add on AGW support with the ldsped program but it's still going to be less-optimal.
I can help you with Linpac since I'm the maintainer but you can technically put anything there as long as it "looks right".
Ok.. and don't forget that Direwolf natively runs on Mac as well.
WINE also runs on the Mac too. --David |

Re: rPi 4 / Signalink USB / Yaesu ft-895 / Direwolf.

Thanks all.? I have a KPC3+ in the garage.? But as you suspect ,I'm hoping to use Direworlf/Raspberry pi as a low level TNC, and then access it over the local area network via port 8000 or 8001.
The rest of my computers are Macs. All the TNC/AGM clients seem to be for Windows.? Does anyone have any ideas? |

Re: rPi 4 / Signalink USB / Yaesu ft-895 / Direwolf.
开云体育Hello Max, KPC3+ TNCs are probably one of the best hardware TNCs out there but Direwolf has better packet decodes than it.? They are pretty good for a "set it up and forget it deployment" but their functionality for a PBBS is pretty low, they haven't received any real fixes or improvements in a decade or more though there are known bugs with them, etc. I suppose they are a good choice for some but a Direwolf setup + some other software will always blow it away. Ps.? If you're just pining for a classic TNC2 like interface, you can run BPQ32 with it's TNC2 emulator + Direwolf to effectively get you the same experience. --David KI6ZHD On 10/04/2021 10:23 AM, J K via

Re: rPi 4 / Signalink USB / Yaesu ft-895 / Direwolf.

Direwolf is a TNC intended to provide lower level set of tools for APRS but it also offers extensive connectivity to OTHER TOOLS using KISS, TCP-KISS, AGW, etc. to support things like terminal programs to make packet connections, run services like NODES, and BBSes, etc.?

Re: rPi 4 / Signalink USB / Yaesu ft-895 / Direwolf.
I have used AGWTermTCP and connect to Dire Wolf through an AGW port for testing. It seems to have the features you are looking for. Also, having AGWMonitor running is helpful can be helpful when troubleshooting as well. Robert Giuliano

Hello. I've gotten Direwolf installed, and it's hearing packet traffic. Printing it out into the REPL or wahtever the terminal window is....but I can't seem to transmit.

Version 3.17 Gary’s comment: Wow, that is 4 years old.? You need to update that.? 3.23.1 is current. I am not sure but came from the apt repository. I didn’t install gpsd initially on this RPI.

Re: USB soundcard on raspi
An easy way to turn off the onboard audio is to comment out dtparm=audio=on in config.txt. # Enable audio (loads snd_bcm2835) #dtparam=audio=on I don't know if that affects hdmi audio because I've never seen that show up in my audio devices list to see that it's missing.

Re: USB soundcard on raspi
开云体育Please note that Fred's recommended StackExchange post comes from March 2018 when maybe PulseAudio was bad news and thus people recommended to remove it.? We are now into late 2021 and I would say that any instructions that recommend to REMOVE PulseAudio from your OS are probably going to break more things than help.? Yes.. I know that the Direwolf v1.6 docs currently say to remove PulseAudio also but it's v1.6 is also old (Oct 2020) and there is a Git Issue tracking the recommend to STOP recommending this. Anyway.. there are various sites covering this topic.? I recommend to search for "raspberry pi sound card enumeration disable hdmi sound device" to get some recommendations.? Most of the answer will be a combination of possibly: ?? - Disabling the onboard audio playback via changes to the /boot/config.txt file ????? or ?? - Disabling HDMI device playback via changes to the /boot/config.txt file and/or blacklisting the snd_bcm2835 sound kernel driver ??? ????? or ?? - Changing the sound enumeration order between the onboard sound chip, USB audio devices, and other devices via the /etc/modprobe.d/alsa-base.conf file ??? It all comes down to what behavior you want. --David KI6ZHD On 09/30/2021 10:42 AM, Fred Hillhouse
