So I’m trying to get the 4.x version working in a headless mode (ubuntu 24.04, no gui). I’ve managed to get the daemon running and prevented it from auto-terminating

But I can’t get it to run SP code from there.

From what I can figure, this should work:

```ruby
require "osc/osc"
client = SonicPi::OSC::UDPClient.new("localhost", SPIDER_LISTEN_TO_GUI_PORT)
client. send("/run-code", TOKEN, "play 60")
# or maybe?
client.send("/run-code", TOKEN, "SOMEPREFIXplay 60")

```

Right? What am I missing here?

Thank you?

Hi there @vomitHatSteve

as this is a dev question - the best place to ask this kind of question is on GitHub via an issue: [Issues · sonic-pi-net/sonic-pi · GitHub](https://github.com/sonic-pi-net/sonic-pi/issues)

That way we get to keep these forums specifically for using the app rather than developing the app (or adjacent tools).

However, that said, I think there’s a good chance you’re sending your `TOKEN` as a string rather than a 32 bit integer. Could you try check to see if you’re sending it as an integer?

Happy to help further over on GitHub if necessary!

Thank you. It’s possible my actual code was treating it as a string, yes. But the test code is definitely using an int.

I will take it over to Github to investigate further tho.
