Send OSC using Raw Packet Sender

[keftaparty]

Hi,
I'm trying to send OSC packets from Smode Station, using the Raw Packet Sender.
I don't know how to format the packet content.
txt file I guess ?
Can someone help me with this ?
Thanks !

Hello!

The raw packet sender object of smode can take any files and send it as a packet.
It's a very simple and low level tool that need computer science knowledges to use it.

I only find this documentation about the OSC packet about how to write inside the file: http://opensoundcontrol.org/spec-1_0-examples
Hope it help you.

The format is raw binary. In general we build our binary files using a network monitor tools such as wireshark.
No support for txt files so far..

Best,

Francis.

Hi,
I've got it working.
I'll try to post a little step by step when I find time for it.

Hi,
sorry to revive an old thread
I'd like help understanding how to use the raw packet sender.

I'm trying to control Philips Hue lights from Smode.

For example I want to send to this path:
http://192.168.1.51/api/Tenk0dnIB4KGFcJf4KSOHybbXCgZ6IlTqXnvDwVY/lights/3/state/

and send message:
{"on":true}

I can't figure out how to use wireshark to convert that message into a raw binary that smode can use.
Any hints much appreciated!

Hi,
Last versions of station integrate a tool to send OSC ( from 8.5 ? at least it's present in 8.6 ).
It's called OSC Packet Sender. That shoud make it much easier for you.

Thanks Mehdi,

but in this case it's not OSC I need to send.
I need to communicate with a rest API, so I guess I need to send actual raw packets, since there doesn't seem to be another way to do that from smode. Did you discover how to prepare the packets for sending in a file?

I already use the OSC packet sender, and it's great.

Thanks

Hi Headfulll
And thanks Mehdi for tech support.

We do not have native Rest Api support in Smode yet.
Of course if sponsored development came, we will do that quickly.

Now you may use Smode RawPacketSender Element to throw arbitrary UDP/TCP paquets.
RawPacketSender2 also allow you to send one packet on IPv4 addresses range but do not support TCP yet.

Concerning Wireshark, you only need to select the "Data" block of the desired packet and "Export Packet Bytes..."
The number of byte of the generated file should be the same of the Data Block (here 340 bytes over 382)
(non exported previous bytes of the packet correspond to protocols header that will be regenerated by RawPacketSender according to custom ip/port...)

Note that RawPacketSender is output only, so if the protocol (Rest?) request bidirectional communication or hand-check, this will never works.

Hoping this can helps.
Warm regards

Hi Alex,
Thanks for that detailed info. You are correct that this will not work for the standard Hue rest API as it does seem to need handshakes. But this was a good learning exercise, now I know a little about raw packets and wireshark, so thanks for that!

By the way, if anyone is interested in using Philips Hue lights with Smode, I did find a good solution using ArtNet and "DMX-HUE" running on node.js, that converts DMX to work with the Hue API. You can find that here:
