ESP Service is a three-layer service infrastructure providing a lifecycle base class, a dynamic service registry, and an optional MCP server for AI-agent tool invocation over multiple transports
iotta codec-board audio IO — ES8311 DAC + ES7210 mic-array ADC over a shared full-duplex I2S bus (esp_codec_dev). Optional Build-B voice backend for the iotta device SDK; wire via Esp32Platform::set_audio().
iotta device SDK — ESP-IDF binding. Runs the portable iotta core (session/protocol state machine, provisioning, MCP, audio pipeline, OTA) on ESP32-S3 by implementing the PAL with ESP-IDF APIs: control plane, voice over I2S, and A/B OTA. Add this component and wire it from your app's app_main (see example/ and sdk/docs/PORTING_NEW_CHIPSET.md).
