How to pair your BBC Micro:Bit with your phone or Bluetooth device.
Pairing’ is what you have to do to have your micro:bit trust another device like a smartphone and similarly, have your smartphone trust your micro:bit. Why ‘trust’? Well, pairing is all about security. You wouldn’t usually want just anyone’s smartphone connecting to your micro:bit and making it do things so by pairing your smartphone with your micro:bit you ensure that only your devices can talk to each other.
Once you’ve paired your micro:bit with another device it also means that they are able to exchange information privately, without someone else being able to “see” the data they’re exchanging over the air using Bluetooth. This is accomplished by data being encrypted and pairing makes it possible for devices who trust each other to encrypt and decrypt data from each other.
