Bluetooth-Microcontroller-IO

Introduction

Useful Python scripts for working synchronously with multiple Bluetooth-enabled microcontrollers running CircuitPython.

This project is subdivided into two directories: central and peripheral.

• Central contains server-side scripts for discovering devices, connecting to devices, and transmitting/receiving data.

• Peripheral contains client-side scripts that are run on BLE-enabled microcontrollers.

Dependencies

• Bleak for Bluetooth communication on central devices.
• Adafruit CircuitPython BLE for Bluetooth communication on peripheral devices.

Usage

A docstring at the top of each script details its function. Generally, a script from the central directory is run on a PC or single-board computer and a script from the peripheral directory is run on a microcontroller. The following Python file name conventions indicate the function:

• Simple: Purely Bluetooth functionality.
• Dotstar: Adds LED indication for boards with Adafruit DotStar LEDs.
• Serial: Reads data via USB connection and transmits it via Bluetooth.
• Handshake: Adds an echo to confirm serial connection.
