The micro:bit app for iOS is available to download from the App Store. Install the app and follow these instructions for pairing your device.


The Android app may request access to Location Services and Storage in order to function properly.



Pairing

To pair the micro:bit with your mobile device you will first need to enter pairing mode:

 

  • Hold down the A, B and reset buttons simultaneously.
  • Release the reset button. The LED screen will fill and you should then see the Bluetooth logo.




 You should then see a pattern displayed on the micro:bit screen.



Copy the pattern into the app



After tapping PAIR you should receive a success message and a tick/check mark appear on the LED display.




You have now successfully paired the micro:bit. 


Press reset to complete the process



Flashing

When the micro:bit has been paired with your iPad or iPhone, you can send your programs to the micro:bit.  You can do this from MakeCode by pressing ‘Download’ or you can select ‘Flash’ on the Home page to send a program stored in the app.


Enter pairing mode again in order to connect to the app and flash a program:

  • Hold down the A, B and reset buttons simultaneously.
  • Release the reset button. The LED screen will fill and you should then see the Bluetooth logo.


Troubleshooting

  • Before you start, it’s a good idea to use a computer to flash a fresh MakeCode HEX file onto your micro:bit, especially if you’ve previously been using Python with your micro:bit. Use your own program or any of our MakeCode projects. You can also use the hex file attached to this article.

  • Make sure you pair your micro:bit and mobile device every time you transfer a MakeCode program.

  • When pairing, make sure you hold down the A + B buttons long enough for all the LEDs on the display to light up.

  • If you’re using batteries to power your micro:bit, make sure they are fresh. Even if the micro:bit seems to be working, it may not have enough power for the Bluetooth radio function to work.
