Hello Danny,

Direwolf v1.7A is a rather old version of the DEV branch as the current version is 1.7E:

?? grep "Dire Wolf DEVELOPMENT" src/direwolf.c
?? --
?? dw_printf ("Dire Wolf DEVELOPMENT version %d.%d %s (%s)\n", MAJOR_VERSION, MINOR_VERSION, "E", __DATE__);
?? --

Can you try that version and report back?? If it still happens there, it might very well be a bug.? If so, can you create a Direwolf Github issue to track this against the DEV branch?

Hello Clinton,

I finally figured the issue with the install (updated commands are helpful) but when running direwolf I get the following errors.

For the "original steps" you were following, where did you read those?? Do you have a URL?

My set up is a baofeng UV5R+, RTL-SDR receiver R820T2, raspberry pi 3B+. Thank you for any help, yes I am new to this. The bold are the red error lines

Can you describe your setup?? Since you 're showing two radios here (a Baofeng and a RTL SDR), I hope you have these connected to two different antennas and they are placed far apart.? Unless you're very careful here, you can destroy your SDR if the Baofeng radio transmits into it.

Dire Wolf version 1.6

Includes optional support for:? cm108-ptt

ERROR - Could not open config file sdr.conf

Try using -c command line option for alternate location.

Please show us how you're trying to start Direwolf (the command line) as well as share us any configuration files.? It's clear here that Direwolf cannot find the "sdr.conf" file from the current directory you're in when you try to start Direwolf.

Audio input device for receive: –? (channel 0)

Audio out device for transmit: default? (channel 0)

This looks as if you're trying to take the output from rtl_fm and send it into Direwolf.? That's fine for receive.

ALSA lib pcm.c:2660:(snd_pcm_open_noupdate) Unknown PCM –

Could not open audio device – for input

No such file or directory

You might be victim to a classic Microsoft copy and paste issue where Windows will translate a "-" hyphen character into a LONGer unicode character that looks similar but it's NOT.? In the command line start up or in the direwolf.conf file, be sure the input is using a real hyphen character.

Exact sample rate is: 1008000.009613 Hz

r82xx_write: i2c wr failed=-9 reg=12 len=1

r82xx_set_freq: failed=-9

Those errors don't look good though maybe not fatal.? Where did you get this RTL dongle?? Not all are equal and some of these are very poorly made, poorly supported, etc.

cd ~

git clone -b dev 

cd direwolf

mkdir build && cd build

cmake ..

make -j$(nproc)

sudo make install

make install-conf

Exactly what commands did you use?

Hi,
I followed the directions for installing direwolf on a raspberry pi and everything was working but when I get to the sudo make install command I get the following:

make: *** No rule to make target 'install'. Stop.

The same thing happens with make install-conf

Any help is appreciated.
thank you

Thanks much. It looks like it worked for the Libasound2. I'll continue with direwolf.

Hello Larry,

I looked over that documentation and while it's nicely written, it's recommending some obsolete things like removing pulseaudio,? I bet when you did that, it asked you to uninstall a lot more packages than what this guide shows as it wasn't written for the Raspberry Pi / Bullseye OS version).? If you search around using '"libasound2" error processing package "elpa-magit"', you'll see all kinds of various issues revolving some long standing bugs.? There are some possible workarounds but I don't know which ones will fix your specific issue.

Ps.? It should be mentioned that a LOT (aka many many people) have tried and failed to create a reliable packet station with Baefeng radios.? It really comes down to your specific radio and how well it was made at the time of it's manufacturing.? Search the Direwolf email archives for all the weird and inconsistent issues that people were combating.? Ultimately, once they replaced their radio with something a bit better made (or even a different Baofeng radio), all their issues went away.

I am in the process of trying the install process described in the?? guide.
This is a Raspberry Pi3 with the latest January 28th 2022 Desktop OS install. When I install the libsound2 I get an error after about 850 lines
I get??dpkg: error processing package elpa-magit (--configure):
it gives several more errors referencing the same package.

As a quick follow up, what are your settings for slot time and persistence per the Direwolf User Guide section 9.2.13?? You can learn how these two values are used to determine when the frequency should be clear to transmit:

?? #Section 6
??

There is also a nice description of DCD in the Tino hardware TNC documentation too:

?? #Section 7

Yes, DCD is "0" before my TX every time so the TX INHIBIT function seems to be working.? It seems as though my issue is from DCD dropping mid-packet and then my station immediately jumps on the false opening and transmits.? I've attached a longer log.? Looks like DCD and PTT don't log time.

Hello Joshua,

It seems as though Direwolf is dropping the DCD occasionally on RX even though the packet gets decoded.? Here is an example:

PTT 0 = 1

[0L] KJ7LVZ>CQ:test <0x0d>

PTT 0 = 0

DCD 0 = 1

DCD 0 = 0

DCD 0 = 1

What was the state of DCD before your station asserted PTT?? I assume it was "0".

Station address, in position 0, is empty!? This is not a valid AX.25 frame.

You should disable the APRS heuristics with say the following:

?? FIX_BITS 0 AX25

??

You can see that the carrier detect started and stopped once before staying on and displaying the packet.? ?I saw a couple that jumped around more than that and still successfully decoding.?

This might be more of a debug display artifact more than anything else.? Try turning on timestamp debugging as well to see if that helps clear that up.?

I have logging turned on but it doesn't seem to log the DCD and PTT to the file, only the packets themselves

That's expected as debug details only go to STDERR.? If you're running on Linux, you can redirect that using the "2>" syntax if you want to log it to a file.

You are understanding me correctly.? I will turn on debugging and see what's going on.

If I'm understanding you correctly, you have a single channel setup on Direwolf as your 300bps TNC.? Correct?? If so, when Direwolf's base logic detects DCD on the signal, it should consider the frequency busy and NOT attempt to transmit on it.? Can you turn on debugging when you start debugging and send us that output that includes DCD and PTT details?
