I’m making a game and I will need to use radio services, however, I don’t know how to simulate multiple hardwares in the editor to test that. Help?

If you include the radio services, then it will pop up another simulator that are connected by radio.

Actually scratch that - the first time a function is run that uses the radio services another sim will pop up.
