The full story
Claude for macOS and Windows can connect Claude Cowork and Claude Code to maker devices over Bluetooth LE, so people can build hardware that shows permission prompts, recent messages and other activity. This official Anthropic repository is the reference and example for that API: an ESP32 desk "buddy" that reacts to what Claude is doing. It has about 2,700 stars.
