Setup
This code depends upon a computer with Bluetooth capabilites, running
Python 3.x, plus the bluezero Python package available from the
Python Package Index (PyPI) and
microbit_uart.py included in this repository. On Linux,
bluetoothctl from the bluez package is also helpful.
Upload the Blocks code to the micro:bit, and then, in On https://makecode.microbit.org/ change the Project Settings: Set Bluetooth to No Pairing Required. (This is not very secure, but the the JustWorks pairing just didn’t work.) Then upload the Blocks code to your micro:bit.
Debian-based Linux systems
On Debian-based systems, type the following at the command prompt ($):
./setup.sh
That should install all the necessary components and edit
microbit_uart.py and substitute the unique addresses for your
hardware into the source code.
Non-Debian-based systems
If you are not using Debian, Ubuntu, Mint, or other Debian-based Linux
system, you will need install Python 3, pip and bluezero
manually, and then determine the address of your PC’s Bluetooth
adapter and the address of your micro:bit Bluetooth adapter. These are
both a series of six 2-digt hexadecimal numbers separated by colons,
e.g. F1:E2:D3:4C:5B:6A. Edit microbit_uart.py and substitute the
two addresses in place of your_pc_bluetooth and
your_ubit_bluetooth. (Leave the quotes in place.)
