Re: Digipeater hearing & repeating itself

This is exactly what I did (with it's own callsign). ?

I guess I was hoping that DireWolf would add itself into the list where it wouldn't repeat that exact same packet for the 30 seconds. ?(Can't think of the exact name of that.) ?

I was think that maybe I had missed some setting to fix it without an explicit filter.

Thanks, Arnold

Hi Arnold,

I had the same issue on my digipeater (still in test on a CHIP).

I got a solution with this filter :

FILTER 0 0 ! b/F1EVM

You need to change F1EVM by the callsign of the digipeater.

Best regards.

My digipeater is hearing its own transmissions, and because it is sending with a path of WIDE1-1, and will digipeat WIDE1-1, it digipeats itself.

So how do I make it so it knows it already sent its own message?

Hope you don't mind if I join in with this Tim as I'm watching this with interest. I have similar problems trying to get GPIO PTT and DCD working with the correct permissions. Despite being able to write to GPIO as my normal user, Direwolf always wants a sudo password.

I haven't tried USB serial PTT yet but I may well do and see if I get a similar result to you.

Re: Audio input device 0 error: Input/output error

#1822

John,?

I have run into a similar error.?

What I found was that the Raspberry Pi processor couldn't keep up with the audio demands at the higher USB speeds. This resulted in dropped USB packets that caused the Rpi to lock up.?

The solution was to force the Rpi to the lower USB speed by adding a parameter to the cmdline.txt?

sudo nano /boot/cmdline.txt

and adding dwc_otg.speed=1 to the end of the text.

?However, this solution is not without its side effects. Some keyboards and mice refuse to operate at this speed. This is not an issue if you are connecting to the Pi via ssh or VNC.

If there is a better solution, I am all ears.?

Direwolf functions flawlessly. The serial PTT functions without issue.

Shutting down direwolf with either a:

[Ctrl] + c

kill -HUP (direwolf process number)

both stop direwolf as expected. However when restarting direwolf with
the same command as before I get the following error message:

ERROR can't open device /dev/PTT for channel 0 PTT control.

the error message disappears when restarting direwolf with sudo.

There has to be a better solution than elevating to root.

What are your thoughts?

Thanks for the info. I'd like to see if I can get it to work with a Project Fi data-only sim card, which costs a penny per megabyte, with no ongoing monthly charge. It's cheap enough to try it for a little while and tinker with the filters if necessary.

For the hotspot hardware, did you find any special needs from the direwolf or pi perspective, or should I be able to use anything that works with the sim card?

DPRS to APRS converter

#1814

I am currently using APRX to convert DPRS from D-STAR radios to APRS and forward it to APRSIS. Specifically, a program called D-RATS parses the position data from D-STAR radios and presents it to TCP port 9500. From there, APRX converts it and sends it to APRSIS. I am looking for a similar function in Direwolf as it would simplify my station. I have read through the User's Guide and have not found any mention of it. Have I missed it? Is that something that could added in a future release?

Audio input device 0 error: Input/output error

#1812

I am experimenting with setting up a "two-way" IGate on a Raspberry Pi 3 running Jessie.

The Direwolf version is the current one, downloaded form GitHub.

I keep getting the error show in the subject line that eventually results in Direwolf crashing. This occurs after about an hour or so of successfully processing packets at a modest pace from traffic on 144.390 MHz. I saw some mention of this in this group earlier on but I am not sure how this was resolved. From the direwolf output console I see:

[ig>tx] WB2UTI>APWW10,TCPIP*,qAC,T2MSSOURI:;TVRH ? ? *241542z2857.01N/08157.51WhThe?

Villages Regional Hospital (WB2UTI) !H4OH!

Tx IGate: Already transmitted maximum of 12 packets in 5 minutes.

Audio input device 0 error: Input/output error

this will occur multiple times until giving up with:

[ig>tx] W4MCO>APWW10,TCPIP*,qAC,T2FRANCE::BLN0 ? ? :Ready for check ins for the?

OCARES Net

Tx IGate: Already transmitted maximum of 12 packets in 5 minutes.

Audio input device 0 error: Input/output error

Terminating after audio input failure.

from dmesg I see:

[ 7276.035136] usb 1-1.2: 1:1: cannot set freq 44100 to ep 0x1

[ 7281.075209] usb 1-1.2: 1:1: cannot set freq 44100 to ep 0x1

[ 7286.660299] Transfer to device 4 endpoint 0x2 frame 594 failed - FIQ timed out.?

Data may have been lost.

This (bad) behavior has been consistent across multiple power supplies ( the usual diagnosis for all RPi problems....) and multiple usb audio devices ( SYBA usb soundcard recommended in the Direwolf docs, and a Signalink USB) Both devices work ?flawlessly under Win 7, BTW.

The RPi3 has only 1 device (the usb soundcard) connected directly (no usb hub).

Not sure what to do next about this...
