Backend:
- api/routes/compile.py accepts board-specific compile options
and dedups in-flight identical requests
- services/espidf_compiler.py expanded ESP-IDF wrapper with the new
options surface (sdkconfig.defaults.in
template added)
- services/arduino_cli.py honour the new options envelope
- services/esp32_lib_bridge.py thread board options through to QEMU
Tests:
- tests/test_compile_request_dedup.py end-to-end dedup behaviour
- tests/test_espidf_options.py covers the new options parsing
Frontend:
- services/compilation.ts client-side mirror — sends the new
options field on every compile request

- Implement tests for BMP280, DS1307, DS3231, I2CWriteSink, and MPU6050 slaves in test_i2c_slaves.py.
- Create test suite for Velxio MCP server tools in test_mcp_tools.py, covering Wokwi utilities and circuit management functions.
- Add tests for parsing WiFi and BLE serial output in test_wifi_status_parser.py, ensuring correct status events are captured.
Replace arduino-cli with ESP-IDF 4.4.7 for ESP32 compilation — Arduino-compiled
firmware crashes in QEMU (9-28 reboots) while ESP-IDF boots cleanly (0 reboots).
The new espidf_compiler translates Arduino WiFi/WebServer sketches to native
ESP-IDF C code, compiles with cmake+ninja, and merges into 4MB flash images.
Key changes:
- ESP-IDF compiler: translates WiFi.begin/WebServer to esp_wifi/esp_http_server
- ESP-IDF project template with QEMU-optimized sdkconfig (DIO, 40MHz, no WDT)
- WiFi status parser for ESP-IDF serial logs (wifi_status, ble_status events)
- IoT Gateway HTTP reverse proxy for ESP32 web servers
- WiFi/BLE auto-detection from sketch content + visual status icons
- Static IP 192.168.4.15 matching slirp DHCP first-client range
- Docker: new espidf-builder stage with ESP-IDF 4.4.7 toolchain
- 157 tests covering WiFi/BLE for both ESP32 (Xtensa) and ESP32-C3 (RISC-V)
