# Atmosic Technologies

> Fabless semiconductor company (San Jose, CA) designing ultra-low-power Bluetooth LE and 802.15.4 system-on-chips for the Internet of Things, built around patented energy-harvesting and controlled wake-up receiver technology with the goal of eliminating device dependence on batteries. Atmosic publishes an EMBEDDED developer surface — the open-source OpenAir SDK on Zephyr RTOS, an AT command set over UART, an atm_isp protobuf schema, and desktop programming tooling — not a public web API. Contract discovery on 2026-08-02 found no OpenAPI, GraphQL, MCP server, AsyncAPI, agent card or /.well-known/ surface on any Atmosic host.
