hi, everyone,
I've been using oscx a lot during the last years but now I face a problem I have not struggled with before. I need to send the same order via osc message to multiple microcontrollers at the same time and it looks like I cannot connect with more than one ip at the same time.
One possibility would be to disconnect from one ip after sending the message and connect again to another ip in a loop iterating over all the ip adresses I need to reach, but I would prefer to do it in a cleaner way for the sake of synchronizity.
Do you think it is possible with puredata?

Thanks a lot!

How about sending to 255.255.255.0, or something like that? I think you can broadcast a message to all devices in your network this way.

@rojele You will need to use Pd 0.51 or newer to multicast in Vanilla...... open the sub-patch [pd IP version and multicast] at the bottom right of the [netsend] help page.

The MrPeach library always could broadcast OSC messages...... see the help file for [sendOSC]

I changed the [connect( message to match my network subnet and added [dumpOSC] to test.
My laptop is at 192.168.1.67..... and it works.

Hi, thanks a lot for your help. It was very useful for me to understand the whole thing.
First of all, finding the "Broadcast address" is needed in order to reach all ips under the same router.
Finding the broadcast address can be done doing some maths acording to your own ip and the given subnet mask. These maths remain obscure for me but are explained here: [https://www.wikihow.com/Calculate-Network-and-Broadcast-Address
](link url)
Finally I used a calculator, this one: [https://jodies.de/ipcalc](link url)

Then, instead of the needed ip in the **connect **message, I put the given broadcast address followed by the port number and here you are! Worked perfectly!
Thanks a lot for your help @alexandros and @whale-av

note: I'm using oscx library, in my case
