This is a program that lets you send events (with optional integer arguments). You can call the events what you want, but the names must match on the micro:bit end.
It is to be used in conjunction with the https://github.com/jaustin/pxt-bluetooth-commands/ extension
This script is suppposed to run in conjunction with the following MakeCode programme:
https://makecode.microbit.org/S05435-27154-54062-42140
Install deps:
pip install -r requirements.txt
Put the example on your micro:bit (amend for your platform)
cp microbit-example.hex /Volumes/MICROBIT/
This script will scroll the name of your micro:bit on the display. Also, you can derive the name from the pairing pattern/graph
Edit the script to change the micro:bit name
open microbit_ble.py
Run the sample
python3 microbit_ble.py
This expects you to write code both on the micro:bit (in MakeCode - https://makecode.microbit.org) and in Python on the host system. You can pick your event names and arguments to represent something relevant to you.
I don't have the concept of a 'response' because it would require tracking events and their response in a more synchronous way - you can layer your own 'response' command over this if you need, I guess.
To present a simple API and to get an idea of what this might feel like, I wrapped the very complete/featurefull KaspersMicrobit library in a little wrapper. You might not want that, in which case the microbit_ble_rawuarts.py file is a good starting point to work against the MakeCode example, or indeed just against a simple MakeCode uart where you can do your own parsing/command interface.
