This repository provides an Arduino library that implements the Bluetooth Low Energy MIDI (BLE-MIDI) transport layer, enabling Arduino boards to send and receive MIDI data over BLE connections. The library works with the FortySevenEffects Arduino MIDI Library and supports multiple hardware platforms including ESP32 (with both standard BLE and NimBLE), ArduinoBLE (NANO 33 BLE), and nRF52. The architecture features a clean separation between the core BLE-MIDI protocol implementation and hardware-specific adaptations. The transport layer correctly handles timestamp generation per the BLE-MIDI specification, running status optimization, and buffer management. Hardware abstractions use C++ templates to provide a consistent interface across different BLE stacks while exposing platform-specific configuration options.
The LLM identified 2 files worth highlighting for reuse:
The core BLE-MIDI transport layer that implements the Bluetooth Low Energy MIDI specification. Handles timestamp generation per spec, running status optimization, and transmit/receive buffer management. Templated to work with different hardware implementations, demonstrating non-obvious skill in correctly implementing the BLE-MIDI 1.0 specification with proper MIDI message parsing and formatting.
A well-crafted BLE MIDI client implementation for ESP32 that manages device scanning, connection, reconnection, and communication. Features proper security handling, connection parameter configuration, FreeRTOS queue-based thread-safe communication, and robust reconnection logic. Demonstrates expertise in BLE client operations with clean separation of concerns and reusable patterns for BLE device management.
