Can the Micro:Bit V2 send or receive multiple radio signals at the same time? I would like to make a radio project, but I am not sure if it will work. Thanks in advance, Brodie ---

Hmmm what are you trying to do exactly? You can certainly send multiple messages in quick succession. ---

@richard I am going to try to make a flight controller for an RC helicopter entirely with Micro:Bit. The code wasn’t working in the simulator, but I think I need to set a slight delay between the radio communications for it to function properly. I come from an RC background, so I have many options for the aircraft, but I am trying to get the code to work before I order any Micro:Bits Thanks for your help. ---

In addition to sending multiple messages as @richard indicated, the micro:bit’s radio protocol is one-to-many broadcast. A single micro:bit can send a message and several others will get it at the same time. They use the radio group to filter our messages, so all communicating micro:bits must be set to use the same radio group. ---

@Brodie How are you testing it? Can you share your code, which may help someone spot any problems? (MakeCode has a “[Share](https://support.microbit.org/support/solutions/articles/19000086289-sharing-a-makecode-project)” button that will result in a URL you can post that will allow others to look at a copy of your code. Modifications would just be in the copy) If the micro:bits will be running different code, you may want to try the Multi-editor: [https://makecode.microbit.org/---multi#](https://makecode.microbit.org/---multi#) . The multieditor lets two different microbit programs communicate. Flight control is definitely possible! MakeKit has Drones that are micro:bit controlled: [https://shop.makekit.no/en/products/air-bit-2-micro-bit-drone](https://shop.makekit.no/en/products/air-bit-2-micro-bit-drone) Bill ---

@bsiever I can’t really share the code since I am testing in Tinkercad. I will probably get multiple Bits, so I can use one in the controller and two in the 'copter. Unfortunately, it may be a while before I am able to actually test it in real life due to personal circumstances, but I will post it once I am done. Thanks for the help. 🙂 ---

Hey @Brodie : You can share work via Tinkercad too. Here’s a project with three interacting micro:bits: [https://www.tinkercad.com/things/g4myzwU9WdS](https://www.tinkercad.com/things/g4myzwU9WdS) It’s a public, tinkerable link. Start a simulation. Each Micro:bit’s Button A will transmit a different message. Receivers will display the message on their screen. Bill ---

Yes, as far as I know it can. You cound use the in-background feature to accomplish that,
