oi,
i was kinda wondering because the ascii and hex/binary examples you gave don’t match.
so googling brought up this saying you can also send all your commands via plain ascii strings which is kinda convenient in v4.
if you want to have it hex / binary you have to start counting byte lengths and encode it after the prefix (kinda like osc does it)
and remember, just because vvvv udp node accepts only string, it’s still just bytes being sent. so binary data in vvvv shows up like a line of garbage string but you can send that too.
