Unreleased

0.2.1 - 2026-05-06

Changed

  • Adopt rustyfarian-ws2812 v0.5.0 retag covering the upstream crate renames led-effects → pennant and ws2812-pure → bunting. Workspace dependency led-effects becomes pennant; rustyfarian-esp-hal-ws2812 feature flag led-effects becomes pennant. All use led_effects::… imports updated to use pennant::…. The two HAL drivers stay on git (not yet on crates.io) so pennant is also kept as a git dep — sharing the source guarantees a single compiled copy and unifies StatusLed / PulseEffect across the HAL boundary.

0.2.0 - 2026-05-06

This release introduces an OTA MVP across both stacks, completes the April 2026 esp-hal upgrade wave, and switches bare-metal Wi-Fi to an async-only API built on embassy-net.

Added

  • OTA MVP — three new experimental crates (ota-pure, rustyfarian-esp-idf-ota, rustyfarian-esp-hal-ota) for end-to-end firmware update
  • Bare-metal async Wi-Fi via the new embassy Cargo feature on rustyfarian-esp-hal-wifi
  • ESP-NOW peer discovery, reliable delivery, and the Peripheral Command Framework
  • Wi-Fi TX power and power-save configuration in wifi-pure
  • MQTT non-blocking publishes, StatusLed boot feedback, and configurable task stack / reconnect timeout

Changed

  • BREAKING — bare-metal Wi-Fi is now async-only; the synchronous WiFiManager surface and the hal_*_connect examples are gone
  • BREAKING — esp-radio 0.18 API renames cascade through rustyfarian-esp-hal-wifi
  • April 2026 esp-hal stack wave: esp-hal 1.1.0, esp-rtos 0.3.0, esp-radio 0.18.0, plus matching embassy pins

Fixed

  • ESP-NOW channel-scan and send_and_wait race conditions

0.1.0 - 2026-03-16

Added

  • wifi-pure crate with WifiDriver trait, WiFiConfig, ConnectMode, MockWifiDriver, and SSID/password validation (ADR 006); rustyfarian-esp-hal-wifi bare-metal stub
  • lora-pure crate with LoraRadio trait, LoRaWAN types, OTA command parser, and MockLoraRadio (ADR 005); rustyfarian-esp-hal-lora bare-metal stub
  • rustyfarian-esp-idf-lora: LoraRadioAdapter bridging to lorawan-device 0.12; idf_esp32s3_join and hal_esp32s3_join examples for Heltec WiFi LoRa 32 V3
  • espnow-pure crate with EspNowDriver trait, EspNowEvent, PeerConfig, WifiInterface (STA/AP), and MockEspNowDriver (ADR 007); rustyfarian-esp-idf-espnow ESP-IDF driver
  • rustyfarian-esp-idf-mqtt: MqttBuilder API with MqttHandle, lifecycle callbacks (on_connect, on_disconnect, on_message), LwtConfig, with_auth(), and publish_with() (ADR 002)
  • rustyfarian-network-pure: MQTT input validation, MqttConnectionState state machine, and ExponentialBackoff iterator for retry logic
  • Dual-HAL script infrastructure: build-example.sh, flash.sh, ensure-bootloader.sh, and xtensa-toolchain.sh for hal_* bare-metal targets
  • Examples: idf_c3_connect, idf_c3_mqtt, idf_esp32_mqtt; hardware reference docs/heltec-wifi-lora-32-v3.md
  • CI: pure-crate test job for all host tests (rustyfarian-network-pure, wifi-pure, lora-pure, espnow-pure)
