2 months ago Thanks for the compliment, but I'm definitely not a C++ expert. There are several parts to the answer here:
- I've done several BLE based projects and already knew most of the concepts I was interested in using (independent of the micro:bit ecosystem).
- I had also worked the the Nordic BLE libraries outside of the micro:bit ecosystem. So I knew some of the things I wanted to do and tricks to get it done. The "BLE LOG" is two parts: the micro:bit end (this repo) and a corresponding Web Browser client: https://github.com/bsiever/microbit-webblelog . (My other bluetooth extension, BLE-HID, has to do several hacks to really work: https://github.com/bsiever/microbit-pxt-blehid).
- Tangents you may be interested in too --- I had university students do a variety of related projects:
- Web-based GUI to get and visualize the data: https://2024-ui-sp.github.io/Micro-bit-ble/ (repo)
- Flutter mobile app: https://github.com/masongaller/MicroSync
- Another Flutter mobile app: https://github.com/a-jeck/microbit_app
- I spent a lot of time looking at the source code to the micro:bit, both for the run-time (called CODAL) and for the MakeCode environment:
- codal-microbit-v2 --- Looks like you're already aware of that one.
- codal-microbit-v2's bluetooth
- MakeCode Bluetooth API Source
- And, of course, there was a fair amount of trial-and-error and debugging....
You may want to join the micro:bit developer Slack: https://github.com/microsoft/pxt-microbit/tree/master/libs/bluetooth (I also try to answer questions there if/when I can. It's pretty low traffic). Sometimes the MakeCode forum is a good place for some MakeCode specific questions: https://forum.makecode.com/c/microbit
I hope that helps!
Hello!
To write this amazing code. I'm working with the Micro:bit v2, and am having trouble understanding what's what with the BLE support infrastructure, when you have to be paired, etc. Thought maybe I could talk to an expert.
Your C++ skills are black belt!
Thanks!!!
