TwoToneDetect TwoToneDetect on a Raspberry Pi - How To

[motomeso]

Managed to get the PiPeater running but I'm now getting these errors.

Are there any known bugs with the ftpupload.py script and TTD?

I have it set in the tones.cfg with ftpupload.py [mp3] but it doesn't seem to be calling the script after the tones. I don't see anything in the log file either where it tried or failed. The script works fine when I run it from command line using the file path.

Can you paste in a sample from your tones.cfg file showing how you are calling it?

Can you paste in a sample from your tones.cfg file showing how you are calling it?

I'm using:

post_email_command = ftpupload.py [mp3]

This is on the TTD RPi image.

Try post_email_command = python ftpupload.py [mp3]

I'm not sure how it ended up that way, but there's definitely a problem in the code. I uploaded a new version to the website, or you can replace this code:

			for i in range(0, int(RATE / chunk * .2)):
				filedata = stream.read(chunk)
				temp.append(filedata)
				filedata = ''.join(temp)
			all.append(filedata)
			audio_data  = fromstring(filedata, dtype=short)

with this:

			for i in range(0, int(RATE / chunk * .2)):
				filedata = stream.read(chunk)
				all.append(filedata)
			audio_data  = fromstring(filedata, dtype=short)

in the .py file.

Any other options to upload calls to twitter since now audio boom wants to charge 10 dollars a month which is way to step

Thanks Andy,

Now how do I only get it to PTT on certain tone sets? I have a tone.cfg file configured and in the same folder but no joy.

Well blonde moment, I was using the PeaterPi instead of the PagerPi code.

I'm getting intermittent decoding on the receive but no transmit. After it decodes it records and transmits but no audio and the transmitter just hangs until the process is stopped.

Here is the error I'm seeing.

Don't bother wasting your money. Even with the $10 account, they dropped support for email uploading. Time to find something else.

Twitter uploads

Direct twitter uploads using python code are possible if you are using a RPi to run TTD. The python code is relatively simple. It is setting your twitter acct up to receive the uploads that is tedious. It also requires that you have an ftp server to upload the audio file to. If there is enough interest, I could probably provide an outline.

I'm interested but I need to purchase another pi and re learn how to set it up. I had crash problems the last time. That may have been because I was running TeamViewer on it to remote in.

IFTTT.com works good for this I am using it now on https://twitter.com/RenfrewCntyScan

Audio Issues

I tried these steps without luck.

When I type: pavucontrol it returns the error: WARNING **: Error retrieving accessbility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by an .service files

The GUI of Volume Control then opens and I see my USB sound card. In fact, I can send audio to it and see the meter raise as I turn up the volume on my radio.

I then exited and typed: pulseaudio - D as you recommend. It states: Daemon startup failed.

When trying to run: ptyhon TwoToneDetect70.pyc it returns:
ImportError. No Module named pushbullet

I'm running the new PI 3 B+. I just can't seem to get the command prompt version to work at all. If I run the Pi version, I get the same long list of errors the other buy posted a few weeks ago. I could try the GUI version. How do I start that on the PI?

Thank you!

It runs on a pi3 but takes several tweaks to get it there and to keep it running. Mostly related to pulseaudio. If you want to give it a go, here are some steps from memory to get you started:

1. Image an SD card with the full version of Raspbian Stretch

2. Do a sudo update and reboot.

3. Install pulse audio. You can do thus using Add Programs under Preferences/Pi configuration or at comand line sudo apt install pulseaudio

4. Install pulse audio volume control. Again, either Preferences or command line sudo apt install
pavucontrol.

5. Make a TTD directory

6. Populate the TTD directory with the TTD version and files of your choice from the .zip download from the TwoToneDetect website. Use the linux version of TTD, NOT the one identified specifically for the pi. You will also need tones.cfg, config.cfg, and TTD.cfg.

7. Create a blank file simply named ffmpeg in the TTD directory.

8. Reboot again

9. Try starting pavucontrol, from command line it is pavucontrol, or in the dropdown under the pi icon under Sound.

10. If you get an error message, close it out, go to the command line and type pulseaudio -D

11. Then try starting pavucontrol again. Hopefully, you won’t get the error message.

12. Once you get pavucontrol running, then open a terminal window, cd to your TTD directory, then start TTD by typing python TwoToneDetect69.pyc or whatever your linux program file is called

13. Cross your fingers...

Let me know how it goes, if anyone tries it. There are several more steps to get it to auto start etc. but those won’t help if you can’t make it run from the command line

When trying to run: ptyhon TwoToneDetect70.pyc it returns:

To fix this, run:

This fixed the problem. Now it looks like I'm back to figuring out how to get the audio selected properly:

Here is the series of errors when running v70 of TDD. As I mentioned below, I can open the Volume Control and see my USB sound card receiving audio from my radio. Any ideas how to fix the errors? Or maybe there is a way to enter GUI mode and select the audio source from a drop down?

If I run LevelMeter.pyc multiple times it shows the same audio sources each time. None disappear.

When I run LevelMeter.pyc I get a bunch of errors but I am then prompted to choose my indexes. I pick "2" for each, as you can see below. It then gives me a set of new errors. Any ideas?

**I attached my log, hopefully that comes through for you to see.

Andy

 

[DrPepper12]

Update.

I make the USB sound card as my default by going to:
sudo nano /usr/share/alsa/alsa.conf

and changing:

defaults.pcm.card 1
defaults.pcm.device 0


I then told config.cfg to use index 3, which is system default. TTD will now open. If I leave my radio open squelch and launch TTD the "Audio Input Level" is all the way to the right. If I turn off the radio it does not move. If I start TTD with the radio off, the Audio Input Level is in the middle. Is this normal? Shouldn't the bar move like it does when you launch it in Windows based on the audio it is receiving. In Volume Control, I do see the level changes, so I know the sound card sees it.

With all that said, I still get errors when launching TTD. See below. The last entry is referring to a input overload, which I can't seem to figure out how to resolve.

Updated Pi Install Instructions

Hi everyone,

Thanks to the efforts of DC31 and others, I've had some success building a TwoToneDetect executable file that will run on the Raspberry Pi. This executable bundles all of the Python dependencies, which greatly reduces the number of steps needed to get TTD running on a stock Pi OS image.

The instructions on the website for getting TTD running on a Pi had gotten pretty out of date, so I updated them today using the new executable files that I just posted on the site. The updated page is here:

TwoToneDetect on a Raspberry Pi | TwoToneDetect

For those running TTD on a Pi, please take a look and let me know if these instructions work for you, if there are things that are unclear, should be added, etc.

Thanks,

Andy
