Bluetooth Low Energy (BLE) presence tracking uses the BLE advertisements emitted by phones, watches, and wearables to determine room-level location — no cameras, no wearable tags, just your existing devices.</p> https://www.pistack.xyz/posts/2026-06-05-ble-mesh-nimble-zephyr-esp-self-hosted-comparison/ Fri, 05 Jun 2026 00:00:00 +0000 https://www.pistack.xyz/posts/2026-06-05-ble-mesh-nimble-zephyr-esp-self-hosted-comparison/ <h2 id="introduction">Introduction</h2> <p>Bluetooth Low Energy (BLE) Mesh is a protocol that enables many-to-many communication over Bluetooth LE radios, allowing devices to relay messages across a network in a decentralized manner. Unlike traditional point-to-point BLE connections, mesh networking scales to thousands of nodes, making it ideal for smart lighting, building automation, sensor networks, and industrial IoT deployments. The Bluetooth SIG standardized BLE Mesh in 2017, and since then, multiple open-source implementations have emerged for building self-hosted mesh networks without vendor lock-in.</p>
