What is the BBC Micro:bit

From Wikipedia:

The Micro Bit (also referred to as BBC Micro Bit, stylized as micro:bit) is an ARM-based embedded system designed by the BBC for use in computer education in the UK. The device has been given away free to every year 7 pupil in the UK, and is also available for purchase by anyone.

More details/videos on the official website.

Instructions

  • You need to flash a hex file on the Micro:bit that enables all the bluetooth services you want.
  • You can use the hex file provided by Martin Woolley for this Micro:bit BLUE app. The file can be found linked in this article.
  • You also need to pair the Micro:bit with your phone. The instructions for doing this can be found at the link above.

Known issues

  1. Bearing value in the Magnetometer service doesn't seem to work.
  2. Issues when multiple services are opened and closed in rapid succession. This is probably related to how subscribing/un-subscribing to characteristics works.
  3. This app hasn't been tested on iOS yet. If you manage to try it out and it works, let me know.

Any bug fixes, feature additions are welcome!
