Gateway Rewrite

This folder hosts the native ESP-IDF C++ rewrite of the Lua DALI gateway.

Layout

• apps/: standard ESP-IDF applications for each firmware role.
  • apps/gateway/main/Kconfig.projbuild: project-visible gateway-role settings such as per-channel native/serial PHY selection, gateway ids, pin mapping, and startup transport policy.
• components/: reusable components shared by all gateway applications.
  • gateway_core/: boot profile and top-level role bootstrap.
  • dali/: vendored ESP-IDF DALI HAL/backend reused from LuatOS, including native raw receive fan-out.
  • dali_domain/: native DALI domain facade over dali_cpp and raw frame sinks.
  • gateway_ble/: NimBLE GATT bridge for BLE transport parity on FFF1/FFF2/FFF3, including raw DALI notifications.
  • gateway_controller/: Lua-compatible gateway command dispatcher, internal scene/group state, and notification fan-out.
  • gateway_network/: HTTP /info, /dali/cmd, /led/1, /led/0, /jq.js, UDP port 2020 command/notify routing, Wi-Fi STA lifecycle, setup AP mode, ESP-NOW setup ingress, and BOOT-button Wi-Fi reset for the native gateway.
  • gateway_runtime/: persistent runtime state, command queueing, and device info services.
  • gateway_usb_setup/: optional USB Serial/JTAG setup bridge; disabled by default so USB remains available for debug at boot.

Current status

The native rewrite now wires a shared gateway_core bootstrap component, a multi-channel dali_domain wrapper over dali_cpp, a local vendored dali hardware backend from the LuatOS ESP-IDF port with raw receive fan-out, an initial gateway_runtime service that provides persistent settings, device info, Lua-compatible command framing helpers, and Lua-style query command deduplication, plus a gateway_controller service that starts the gateway command task, dispatches core Lua gateway opcodes, and owns internal scene/group state. The gateway app also includes a gateway_ble NimBLE bridge that advertises a Lua-compatible GATT service and forwards FFF3 framed notifications, incoming FFF1/FFF2/FFF3 writes, and native raw DALI frame notifications into the matching raw channel, and a gateway_network service that provides the native HTTP /info, GET/POST /dali/cmd, /led/1, /led/0, /jq.js, UDP control-plane router on port 2020, Wi-Fi STA lifecycle, the Lua-style LAMMIN_Gateway setup AP on 192.168.3.1, ESP-NOW setup ingress for Lua-compatible connReq/connAck/echo/cmd/data/uart packets, native raw DALI frame forwarding back to connected setup peers, and BOOT-button Wi-Fi credential clearing. Startup behavior is configured in main/Kconfig.projbuild: BLE is enabled by default, Wi-Fi STA and ESP-NOW setup mode are disabled by default, and the built-in USB Serial/JTAG interface stays in debug mode unless the optional USB setup bridge mode is selected. The gateway app exposes per-channel PHY selection through main/Kconfig.projbuild; each channel can be disabled, bound to the native DALI GPIO HAL, or bound to a UART1/UART2 serial PHY. The checked-in sdkconfig is aligned with the app's custom 16 MB partition table so the Wi-Fi/BLE/network-enabled image fits the OTA app slots.
