send body?

[stepir]

apologies for the noob questions...

I need to make a WebSocket call, it works as I wanted using a Mac client I found in the App Store:

What would be the equivalent using websocat?

Thanks

What have you tried? What do you mean by "body"? A WebSocket message? A body in Connection: Upgrade HTTP request used for connecting to a WebSocket?

For the first one, just echo /opt/key/up | websocat ws://192.168.1.169/ may be sufficient.

Thanks!

I'm not sure what body mean in the WebSocket client for Mac (the posted screenshot), but if I send it - the server will produce the expected change (it's changing view on an exposed rtsp stream camera).

If I use this I don't see any particular error but it will not produce any view change:

You may want to use -n to see the error as echo | websocat immediately closes the connection after sending a message.

ok but I don't see any other output:
