Microbit Bluetooth Starters

Pairing Instructions (from Microbit)

1. Hold down buttons A and B on the front of your micro:bit together. The front is the side with two buttons and the LED display. Keep the two buttons held down. Don’t let go of them yet!
2. While still holding down buttons A and B, press and then release the reset button on the back of the micro:bit. Keep holding down buttons A and B.
3. You should see “PAIRING MODE!” start to scroll across the micro:bit display. When you see this message start to appear you can release buttons A and B.
4. Eventually you’ll see a strange pattern on your micro:bit display. This is like your micro:bit’s signature. Other people’s micro:bits will probably display a different pattern.

Troubleshooting

• If you see the error

  GATT operator failed for unknown reasons

  open up your Bluetooth settings on your computer and remove your Microbit from the list of devices. You will have to repair the Bicrobit from scratch, but you should then be able to connect to its services correctly.
• If you see a frowny face and error code appear on your Microbit, try resetting it to its factory settings using the instructions found here. Note this will remove any current program on your Microbit!
• If you keep seeing a checkmark appear on your Microbit's LED array, reset your Microbit and re-pair. The checkbox is the default state to show right after the Microbit has been paired for the first time.
