summary
Bluetooth Mesh runs over BLE, supports 32,000+ nodes, and routes by relaying (recommend ~5% relays) with configurable TTL up to 127 hops. It uses publish/subscribe groups, standardized models (on/off, lightness, HSL) with set/get/status messages and prefers unacknowledged sends for scalability. Security uses provisioning and AES-CCM network/app keys. Zephyr RTOS ships samples and runs mesh on small boards (~200 supported); a 16-node Zephyr demo with a proxy and a browser interface shows a Web Bluetooth proxy demo worked and there are about 200 certified products.
