Hi,
So the "bu" command imitates the actual press of the button in the Cuety interface. When pressed shortly, this is a Go+ command. When pressed longer, it will release the playback.
The same will happen with this UDP command. You will have to send a "...bu=1" for the pressing of the button, and a "...bu=0" for the release of the button.
If you send these immediately after each other, it will be a Go+
If you send these with a pause, or don't send the 0 value at all, it will be a release.
If you want to prevent this behaviour, you can use the go+ and release commands instead of the "bu" (button) command.
Greetings,
Bootsy
