[ANSWERED] TCP or UDP server in Isadora 3?

merni

Hi all

Would like to trigger a scene in Isadora 3 on Windows 10 using a TCP or UDP client. Isadora should be the server.

Does anybody know, if there is a way to achieve that? I just need to receive some command strings.

Of course, the OSC would be possible but with the necessary implementation of OSC on the client side. Another approach is to use a server inbetween, where Isadora and the other client connects to.

But is there a possibility to do an TCP or UDP server inside isadora?

Thank you for your help

Hi,

I have not seen an implementation of a server inside an Isadora patch, I don't think that is possible.

You will find some information useful in this thread. In particular the Node-Red implementation appears to be an option for what you are describing.

What exactly do you want Isadora to do? Isadora can send via TCP and receive via TCP.

Hi,

Thanks for your answers.

I use several RaspberryPis to communicate to different devices (e.g. Lightning Desk) ect. in my show. There, the RPi is always the client and the other device is the server.

Now I also need to send a start signal from the RPi to Isadora to trigger the start scene. Since I am using python and already have a UDP client programmed, it would be the easyest way to just have a UDP Server on the Isadora side.

Since it seems not possible so easily, I either use a webserver inbetween where the RPi and Isadora can connect to or I build a UDP or TCP server in python on the RPi side, but this will take some time.

Are there other, easy to implement, posibilities?

Thank you for your help

Sending OSC from Python is a snap. I would think that adding that functionality would be very quick.
But you could also send a TCP message. I think there are a number of options, but OSC might be the easiest.

@merni if you are lazy you can send a upd message that is formed in the same way as OSC, OSC is just UDP with some formatting. I have done this before and it works fine. As @DusX says, adding OSC to python is trivial if you got this far.

Dear all

Thank you for your help an input. With OSC, it was pritty easy to solve. I used a python OSC library (https://pypi.org/project/pytho...) and it works very easy on the python as well as on the isadora side. Problem solved.

Thank you for your help.
