I am trying to create an application to listen to as many nearby micro:bit which sends radio on a particular group. I have read a lot about BLE connection and uart, but my project would benefit for a one-to-many transmission similar to the microbit radio.
Is it possible to listen to Micro:bit radio with App Inventor?
A lot to read via this link on my website. Unfortunately, the MIT extension for Micro:Bit is a mess and probably won't work at all with Micro:Bit2. MIT are working on a new extension, but in the meantime you can use the BLE extension to communicate.
