Trouble shooting sending OSC "program as a service"

simonb

Hi Sorry me again.

So I went though setting up as a service. Instructions are great and the program runs in the background sending OSC to PD on my attached laptop.

https://learn.bela.io/using-bela/bela-techniques/running-a-program-as-a-service/

However when I try and run it in the backround. (I change the address to localhost re compile) and it doesn't do anything to the same PD patch running on the Bela.

Here is a snippit from the


include "Adafruit_TSC2007.h"
#include <libraries/OscSender/OscSender.h>

// hostAddress should be "localhost" if sending to another application on Bela
// or 192.168.7.1 or 192.168.6.1 if sending to a port on the host computer

// this works and sends to computer when program running as a service
const char* hostAddress = "192.168.7.1";

// when I try to change to this it still runs but has no effect on the same pd patch. This time on the Bela
//const char* hostAddress = "localhost";
int hostPort = 1234;
unsigned int sleepMs = 50; // sleep time between reads

Here is screen shot of the PD patch which as I said is responsive on my mac.

And here is a console dump.

Any ideas what I am doing wrong?

I struggle a bit to understand the log you posted, I assume that is a copy/paste of the console at the bottom of the Bela IDE, where there is a mix of messages printed from building/running/stopping the current program and the execution and output of commands you run in the console itself. Unfortunately, the project names are not printed, which makes things complicated for me to understand.

In one point you have this which would send to a Pd patch running on Bela:

Sending to localhost:1234

elsewhere you have:

Sending to 192.168.7.1:1234

which would send to the host.

Why does this not show any output from the service? Can you show the content of /lib/systemd/system/Adafruit_TSC2007-OSC.service ? Is it actually using the file that you have been building in the project? Or a copy of it?

simonb root@bela ~/Bela# journalctl -fu Adafruit_TSC2007-OSC

As a note, that console in the IDE is very limited, so you should not use -f for journalctl (or run any other commands that do not return automatically) there as that will result in not being able to run more commands until you reboot.

giuliomoro

you can also use the "download all projects" button from the IDE's settings->other system functions and post them here if that helps me troubleshoot the issue.

simonb

I followed the instructions so it seems like my project is here

/root/Bela/projects/Adafruit_TSC2007-OSC/Adafruit_TSC2007-OSC

Then I created this file.

Adafruit_TSC2007-OSC.service

And moved it using.

mv /root/Bela/projects/Adafruit_TSC2007-OSC/Adafruit_TSC2007-OSC.service /lib/systemd/system/

[Unit]
Description=Adafruit_TSC2007-OSC Launcher
After=network-online.target

[Service]
ExecStart=/root/Bela/projects/Adafruit_TSC2007-OSC/Adafruit_TSC2007-OSC
Type=simple
Restart=always
RestartSec=1
WorkingDirectory=Adafruit_TSC2007-OSC
Environment=HOME=/root
KillMode=process

[Install]
WantedBy=default.target

So I am sure it works and I can edit the project and get it working and then change to localhost and break it again... when it is set to send to the host computer it sends fine. But when I change that to local host things go wrong.

I added this bit of code into it and strangely it prints "sending_osc" when set to send to the host computer but not when I try changing that to localhost.

if(touch.read_touch(&x, &y, &z1, &z2)) {
			oscSender.newMessage("/tsc");
			oscSender.add(x).add(y).send();
			printf("sending_osc\n");

Another interesting thing is when I run the service in either case using the command.

systemctl start Adafruit_TSC2007-OSC

I am 99% sure the project runs in all cases because the led flashes on the i2C board.

Does that help at all?

Thanks

giuliomoro

Add some extra prints in the code: once at the beginning of main, one after each statement and see if you can figure out where it hangs. Is "Found touch controller" being printed at all? If you set a different IP, e.g.: 192.168.7.2 or 127.0.0.1, does it print something more?

Also replace WorkingDirectory=Adafruit_TSC2007-OSC with WorkingDirectory=/root/Bela/projects/Adafruit_TSC2007-OSC/. Not that that should fix it, but it should get rid of the warning.

simonb

So this runs as a project and prints to the terminal all through the code.

#include "Adafruit_TSC2007.h"
#include <libraries/OscSender/OscSender.h>

// hostAddress should be "localhost" if sending to another application on Bela
// or 192.168.7.1 or 192.168.6.1 if sending to a port on the host computer

// this works and sends to computer when program running as a service
const char* hostAddress = "192.168.7.1";

// when I try to change to this it still runs but has no effect on the same pd patch. This time on the Bela
//const char* hostAddress = "localhost";
int hostPort = 1234;
unsigned int sleepMs = 50; // sleep time between reads

int main()
{
	Adafruit_TSC2007 touch;
	OscSender oscSender(hostPort, hostAddress);
	if (!touch.begin()) {
		fprintf(stderr, "Couldn't find touch controller\n");
		return 1;
	}
	printf("Found touch controller\n");
	printf("Sending to %s:%d\n", hostAddress, hostPort);
	while(1)
	{
		printf("made it to the while loop\n");
		uint16_t x, y, z1, z2;
		if(touch.read_touch(&x, &y, &z1, &z2)) {
			oscSender.newMessage("/tsc");
			oscSender.add(x).add(y).send();
			printf("sending_osc from the if loop\n");
		}
		usleep(sleepMs * 1000);
	}
	return 0;
}

When I run it as a service it works and sends OSC to my host computer but does not print to the IDE terminal.

Still not managed to pick it up within 'local host'

Added a load bang to my PD patch above. forgot to mention I can hear the sine waves fine.... Still they are not changing frequency like my host version and obviously no OSC messages being printed to terminal from the C project or the PD patch.

thanks

giuliomoro

Not sure what you expect the loadbang to do and what it doesn't do... just checking, is the _main.pd file in the same folder as the Adafruit_TSC2007-OSC/ project?? That won't work, it needs to be in a project of its own.
That is to say, a project containing a main() function will not load any Bela or Pd stuff. It will simply execute the main() function. If you want to run one such project (e.g.: Adafruit_TSC2007-OSC) alongside a Pd patch on Bela, you need to first run that project as a service and then open a different project, where you'll have only the Pd patch and run that.

simonb When I run it as a service it works and sends OSC to my host computer but does not print to the IDE terminal.

Programs running as service won't print to the terminal, you need to use journalctl to see their output.

simonb Still not managed to pick it up within 'local host'

did you try the IPs I suggested?

simonb

Hi so.

The Adafruit-osc project is selfcontained. I change it etc. Then run it in the background.

Then the Pd project is a separate project so I move over to that.

I ran Jounalctl on a localhost version. And it seems to be working.

Your code is printing to the console too quickly. Check your audio thread for print messages.

I was just messing with PD and put in Loadbang to try anything really. It is in the OSC recieve example so thought it might do something. But like I said. I can hear the sinewaves so its working.

Cheers

giuliomoro

What if you print the output of netreceive directly? Just in case something goes wrong when osc parsing?

Or try sending to netreceive from a netsend within the same pd patch? Also try changing port in case that one is taken and you are missing the error message

simonb

Ok its something to do with my PD patch.

changed the port to 7562 in Adafruit_TSC2007-OSC and the bela recieve osc example prints. Horaay.

Bela version now working.

My version running fine and tested with bela on host but not working on Bela

giuliomoro

simonb My version running fine and tested with bela on host but not working on Bela

So was this patch not working or was it a filename issue?

giuliomoro

I should say : for me it works as expected: running this as a service and running this Pd patch prints all that it needs:

simonb

Solved..

Ah apologies... Its my fault for not using _main.pd.... I should have known better and had done this before but forgot because I was sure the problem was in the service and sending the OSC etc....

Thanks again for your amazing support.

Best wishes

Simon

simonb

It was because I was dragging a patch that wasn't called main into bela so I think it was compiling on Bela without some of the required libraries. It worked enough to make sound but not to catch the OSC.
