TwoToneDetect TwoToneDetect on a Raspberry Pi - How To

[KK6ZTE]

Yes, I get the following:

Otherwise it's working perfectly. I had to change some tones slightly compared to my Win7 PC, but it's working great, just sending wav files. Thank you for the help and for this awesome software!

And if I understand correctly, you're getting a "FFMPEG NOT FOUND" statement when TwoToneDetect starts? That's odd.

Here is something you can try at the command line:

python
import subprocess
subprocess.check_call(['ffmpeg','-version'])

If that completes without error, TwoToneDetect should be finding ffmpeg.

If instead TTD on startup says "FFMPEG FOUND" but it's still not creating mp3 and amr files, it may be a compatibility issue with the version of ffmpeg you're using and we can dig deeper into that if needed.

It comes up with similar results to the previous command, no error.

FFMPEG NOT FOUND
pulse selected as audio input device
pulse selected as audio output device
SLO COUNTY FIRE
Successfully retrieved local tone info at 18:45:24 on 06/28/19
Successfully retrieved local tone info at 18:45:24 on 06/28/19
Tone1

Other than no ffmpeg it works good.

Sometimes I'll get

Done recording SLC Station 21 SLO Airport 08:25:22 on 06/29/19

going to try to copy files now

IOError: [Errno 2] No such file or directory: './audio/SLC_Station_21_SLO_Airport_2019_06_29_08_24_46.mp3'

Which I assume is due to ffmpeg not being found that there is no mp3 file generated, but then it doesn't send the email.

What model pi and which OS are you running?

 

[KK6ZTE]

It's a Pi 3B+ with Buster. Andy's logged in remotely for some testing. He thinks it's an issue due to the newer OS and ffmpeg

 

[DC31]

Good. Same place I was going...

 

[KK6ZTE]

The test 71d has been working on my machine since Tuesday night and made it through the big county-wide quickcall test yesterday with no hiccups, even on Buster.

I sent you a Private Message

I'm just starting out and I too want to run TTD without all the logs appearing...Can you tell me what you told @rparker87

I don’t remember that discussion.

 

[medic459]

I don’t remember that discussion.

Sorry...I thought you showed someone how to run it without all the output to the screen. I guess the best way is to just 'hide' it by running it thusly:
screen -d -m ./TwoToneDetect71d

I was just wondering if there was a way to start the app itself without output (vs simply hiding it).

 

[DC31]

Okay, when running it in a screen I have used the parameter -dmS. d detaches the screen, makes it not visible like you want. m creates a new session. S allows you to name the screen.

Then you use -r to reattach the screen when you want to see it. Then cntrl a d to detach it again.

Since you are running 71d you might want to try running it headless (in the configuration parameters), then access the control interface through a web browser. Localhost:8080 or piipaddress:8080

I'm running this on my Pi. I have these in the config.cfg file:
instance_id = Port 8081 ;Put text here that you want to appear in the title bar of the program start_headless = 1 ;Start in headless mode (no GUI) gui_remote_access_port = 8081 ;Port over which to access the GUI from a remote computer via HTTP (web browser)

When I try to go to 8081 I get:

Error: 404 Not Found
Sorry, the requested URL 'http://10.20.30.40:8081/' caused an error:

Not found: '/'

 

[DC31]

Try http://10.20.30.40:8081/index.html

 

[medic459]

Try http://10.20.30.40:8081/index.html

Fantastic!!! Just need to put in a cron task to start it on reboot and check/restart if it dies and viola!
Thank you so much!
One last thing (for now, I hope): Is there a way to stop it from logging the 2x per second audio entries?

[DC31]

In TTD window on your web browser, adjust the squelch slider so that it only shows audio entries when there is radio traffic.

What version of Raspbian are you running on the pi? Stretch or Buster?

PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"
NAME="Raspbian GNU/Linux"
VERSION_ID="10"

and the squelch worked like a charm....Once again, you are my hero.

I tried to search the thread here for any details pertaining to my issues with a fresh install but couldn't seem to find anything. I currently am running version 67 on an old raspi model 2. I recently purchased a raspi model 4 to replace my slower, outdated model 2 which does not have internal wifi. Everything went good, until I wasn't able to select my USB soundcard for the input. In addition, I'm unable to get the program to start when the pi 4 is booted. Does anyone have an image running a more current version of TTD (71d) on a model 4 raspberry pi that they would be willing to share? I'd greatly appreciate it since I had to do a clean install. (the older image file of version 67 would not boot on the model 4 raspi)

Thanks in advance!

Are you using Pulseaudio Volume Control to select the sound card?

Yes, I am.
