APRS WebChat Start Failure.

[elliott paddock]

Hi, I’m new here and not skilled in raspberry pi’s. I’m trying to start the aprs webchat over hf aprs, but nothing happens when I beacon. no tax on my 7300. I looked at the sys log and see this error, but not sure how to fix it. Any help is appreciated.

Hi Elliott,

This suggests the APRS TNC/Igate is not running (either didn't start or died).  You
can click PktLog to confirm this.  It can die when RF gets on the audio/usb cables.

In any event, direwolf isn't responding on port 8001 which aprsd/webchat needs
to send/receive packets.

cool,

Thanks, Craig. The Kiss TNC fails to start due to erroring out before i even attempt to send RF so would there be another reason for the startup failure? This is with my 7300 not powered on.

Interesting. I thought when Direwolf starts it needs to see a interface to the radio. So if the radio is off so too is the interface? How are you connected between teh digpi host (I assume a Raspberry PI) and teh radio?

[elliott paddock]

i’m using a pi zero 2w that connects via usb to my 7300.

Hi guys, direwolf MUST be running so webchat can connect.

PktLog will give you the status of direwolf.

Normally, starting the web chat service also turns on APRS TNC/Igate.

if the ic705 is off, direwolf will die with the USB port going down.

if the ic7300 is off and plugged in, USB stays up, direwolf stays up.

in my experience,
