C++ MIDI 2.0 platform: a C++17 callback-first wrapper that bundles the portable midi2 C99 core. Covers UMP transport (M2-104), MIDI-CI with Appendix E (M2-101), Property Exchange Subscribe/Notify, Profile Configuration, Process Inquiry, Flex Data, and Bit Scaling (M2-115).
blifi: BLE-based Wi-Fi provisioning for ESP32. Provision Wi-Fi credentials over an encrypted BLE session (X25519 + AES-256-GCM, gated by a Proof-of-Possession) instead of a hotspot/captive portal. Includes a NimBLE GATT transport, Wi-Fi station manager with NVS persistence and retry/backoff, and an optional reset-pin factory reset. Companion Flutter package: `blifi` on pub.dev.
ESP-IDF component for firmware updates via GitHub Releases. Polls the GitHub API for new releases, downloads the .bin asset, and flashes it. Supports partial HTTP download, OTA resumption across reboots, and anti-rollback (software semver check + hardware secure_version eFuse check).
