TwoToneDetect TwoToneDetect on a Raspberry Pi - How To

[DC31]

TTD Installed on Pi3, OS is Raspbian Stretch.

I get the Text-Only email when my tone goes off. I do not receive any AMR or MP3 email with the tone. Is this an issue with FFMPEG?

I did the command below:

sudo apt-get install ffmpeg

After install, I had to go find the ffmpeg which I found under directory .usr/bin

Is this the correct ffmpeg?

Thanks!
Jeff

Take a look in your logfiles directory for the most recent logfile. See if it contains an error message, probably like "file not found" Copy the error message to a reply to this post and we can figure it out.

Hi All, Been running TTD on a pi for a few years now as a backup for our fire department radio dispatch, and I just updated our call out list and have run into a weird problem.
The Pi fires out a different set of texts and emails for two different tones, one set works fine, but the set that I recently updated only sends out the first text, the first AMR and the first email.
When I go in and look at the logfiles, there are no commas between the phone numbers on the tone set that is not working properly. However, there are commas present in the "tones.cfg" file, and I can see that they are being sent to the Pi
Here are the two pieces of the logfile (Names and numbers have been changed)

When the tones.cfg file is loaded:
text_emails = "Corey Smith"<5867286251@pcs.rogers.com>,"Steve Flann"<5866257310@pcs.rogers.com>,"Randy Williams"<5863542490@txt.bell.ca>

Then, when the tone is detected;
Text Group Email sent to "Corey Smith"<5867286251@pcs.rogers.com>"Steve Flann"<5866257310@pcs.rogers.com>"Randy Williams"<5863542490@txt.bell.ca>

And only Corey Smith gets the text. As I say, the other tone, with the other set of numbers works fine.
Thoughts?

Hey y'all. I have a feeling I'm missing something really basic here.

Trying to run TTD v70 on RPi 3B with Stretch. It will not run from the command line, I'm assuming, because none of my audio devices are called pulse. I can manually start TTD from the GUI without a problem, and I have pavucontrol auto starting when the GUI starts. The problem I'm having is that everything I've tried to get TTD to start doesn't work. I assume it's because it's trying to start from the command line, which doesn't work.

How the heck do I auto start the v70 executable in the GUI? It's probably something obvious and I'm just too tired to see it or find it in this thread.

I ran into a similar problem once. Mine turned out to be related to the fact that there are actually two types of double quotes in the computer world; straight quotes as yours above appear to be, and curly quotes where the beginning and ending quotes are different. I had to figure out how to make my Mac keyboard always use straight quotes. Maybe there is more than one type of comma?

Copy both lines to a plain text editor and look closely at all the characters to see if you can detect a difference. Maybe simply copying them back to TTD from the plain text editor will fix the issue?

I don't know that I can directly answer your question. All that I can do is to tell you how I do it. I am no linux guru, so it may not be the best or most accepted method. But, it works.


Navigate to your /home/pi/.config/autostart directory from the command line. If the directory doesn't exist, create it.

Then at the command line in that directory type:

sudo wget http://twotonedetect.net/burnham/TwoToneDetect69a/TwoToneDetect.desktop

That will put a file in that directory called TwoToneDetect.desktop. This will execute when the GUI starts.

Open that file using the nano text editor (sudo nano TwoToneDetect.desktop) and modify the Exec= line putting in the command that you use to start TTD from the command line.

Regarding starting it from the command line, try going into your config.cfg file and set the input device index to 0 (zero). It wants to look for the "default" device rather than "pulse". This was a Stretch change.

This all comes with no warrantee expressed or implied!

Thanks Jim; still no dice though. I tried pointing TwoToneDetect.desktop the the executable, it didn't work. I downloaded the non-pi version and pointed it to the .pyc, it didn't work. I removed the sh script and delay entirely, it still didn't work.

I'm going to roll back to Jessie and v69 and try to get things working.

 

[ispepnam]

I got it working now. I used the Ubuntu image DC31 provided in July 2016. It detects tones, records, fires off emails, and activates my python scripts that are controlling things over GPIO.

Now I just need to get an RTL-SDR piped into TTD and I'll have the tiny package I'm looking for.

Keep us posted on how you do on the RTL-SDR part. I have spent countless hours/days/months working on that trying to use the rtl-sdr as a source for TTD. While I have made it work, it is nothing that has stayed working for very long.

There is a lot of detail in this forum thread that you might not find due to its title:

https://forums.radioreference.com/s...rcraft-am-atc-broadcastify-using-rtl-sdr.html

There is a LOT to read through but it clears up some of the squelch and various forks of RTL-SDR variables that you will need to work through. One of the challenges is that rtl-sdr outputs audio to stdout, not to a sound card.

To get the basics of sdr on the pi you may want to experiment first with GQRX to get a handle on some of its workings in a GUI environment.

Gqrx SDR for the Raspberry Pi &#8211; Gqrx SDR

I tried running GQRX and inputing it into TTD just last night. GQRX itself requires about 75% CPU. Running both of them caused crashes.

I tried running GQRX and inputing it into TTD just last night. GQRX itself requires about 75% CPU. Running both of them caused crashes.

My plan (right now) is to use RTL_FM from the command line. It *should* be able to pipe raw audio to TTD without too much hassle. I've gotten RTL_FM working in Jessie for a different project, and it doesn't need too much CPU, but I'm not sure how Ubuntu is going to like it. Hopefully, like Jessie, the SDR just needs some drivers installed and others blacklisted to make it work.

I'll give an update if I get it figured out.

I could use some help with TwoToneDectect on Raspberry PI

I am attempting to run TwoToneDetect in a headless config.

It seems to me that I am having an issue with ffmpeg. It would also be nice to be able to cleanup the ALSA errors. Any pointers on how to fix my issue or cleanup the startup would be appreciated.

Thanks in advance -Jason

In the startup script I have this set (I also ran this before I started it in this test).
export PULSE_SOURCE=alsa_input.usb-C-Media_Electronics_Inc._USB_Audio_Device-00.analog-mono
export PULSE_SINK=alsa_output.usb-1130_USB_AUDIO-00.iec958-stereo

K1jak,

I think you want to focus your attention on this:

All the other error messages are either normal or as a result of this error.

Does TTD run properly if you don&#8217;t set the pulse source/sink? It should find the card unless you have multiple sound cards installed.

As for the long list of alsa errors, those are related to the features of the sound card that TTD doesn&#8217;t use. The more complex the card the longer the list. We are not looking for Dolby Surround Sound only simple mono audio. In my opinion, the cheaper the sound card the better.

As for the long list of alsa errors, those are related to the features of the sound card that TTD doesn’t use. The more complex the card the longer the list. We are not looking for Dolby Surround Sound only simple mono audio. In my opinion, the cheaper the sound card the better.

It looks like the issue was that I took someones tones.cfg that was built on Windows.

They had mp3_Emails=
Changing it to: mp3_emails looks to be the fix.


Now I am just getting two sets of SMS for each call.

Correction it wasn't the mp3_Emails=

When debugging I did additional cleanup I had removed:
playback_during_record = 1

I went to the station to setup pushbullet and added the playback_during_record back in and it stopped working again.

I removed it and I was then working again.

My next issue probably needs to go to another thread but TTD is uploading to the pushbullet correctly but pushbullet isn't proving any notification on IOS or Android. Any thoughts on where I should take my pushbullet question?
Thanks -Jason

Audio Issues

So I have this up on running on a raspberry PI and can see audio coming into the sound card via the pulse audio GUI, but do not see this registering in the TTD GUI....any idea what I am missing here?

1. Make sure that you have the input device set to default and the output to the pi sound card.

2. In PAVucontrol go to the Recording Tab. Make sure that you have the USB sound card selected.

3. Again in the Recording Tab, make sure that you don’t have it muted.

4. Adjust the slider in the TTD window.

Thanks DC31, that fixed that issue. That works great....now, next issue:

I am trying to have this autostart Pulse and TTD in terminal on startup with the following:

[Desktop Entry]
Encoding=UTF-8
Name=Terminal autostart
Comment=Start a terminal and list directory
Exec=/usr/bin/lxterm -e 'ls -l | /usr/share/applications/pavucontrol.desktop'
Exec=/usr/bin/lxterm -e 'ls -l | /home/pi/TTD/TwoToneDetect70'

That works and both programs run. TTD appears to be "listening" and can see the audio in the GUI. However, when I send test tones it does not detect them.

When I open a terminal and start the program with /home/pi/TTD/TwoToneDetect70, it seems to work, but will not detect my tones.

When I double click on TwoToneDetect70 in the /home/pi/TTD directory and choose "Execute In Terminal", it works perfectly and detects my tones and sends the email as desired....

I'm at a loss with this one.

Any ideas?

 

[tdpearce]

it seems I may need to run this x-terminal-emulator, perhaps?

 

[tdpearce]

I tried to manually start it from the x-terminal-emulator and it wouldn't detect my tones either, the only time I can get this to detect my tones is when I double click TwoToneDetect70 in the directory and choose "Execute In Terminal"

Edit: The program does detect my tones when I double click and choose "Execute"

EDit #2: if I open a terminal and type cd TTD then /home/pi/TTD/TwoToneDetect70, it works fine
