Hello, i want to send messages (using radio) between three micro:bit devices, but i don’t know how to add other micro:bit using only Makecode with no real micro:bit. i did open two projects at the same time and set the radio group to the same number but message could not be transmitted between two projects. Please let me know how to do it if it is possible. thank you. ---

I don’t think we have support for this. ---

If you want to send messages between two different projects, you can use the “Multi Editor” to test your work: [https://makecode.com/multi#](https://makecode.com/multi#) . I think it only supports two micro:bits, not three. ---

If you want to simulate the basic behavior, you can simulate radio with three (or more) micro:bits via TinkerCad. Here’s an example: [https://www.tinkercad.com/things/diPZ3rFXPXE-basic-microbit-traffic-lights?sharecode=hvaCbwe\_7NJztPuc83-eceR4kXavNRGDXDqfzkBuyQo](https://www.tinkercad.com/things/diPZ3rFXPXE-basic-microbit-traffic-lights?sharecode=hvaCbwe_7NJztPuc83-eceR4kXavNRGDXDqfzkBuyQo) It’ll take a little effort to convert code back-and-forth between Tinkercad and MakeCode, but Tinkercad’s block are pretty consistent with MakeCode.
