In 2017 the Bluetooth SIG introduced Bluetooth Mesh on top of the Bluetooth v4.2 specification. In difference to classical Bluetooth and BLE, the new technology allows many-to-many communication by using advertising channels only. It is based on a forwarding mechanism (relay-function) and a publish/subscribe method for data exchange. Bluetooth Mesh is not limited by the direct connection range.
The LOYBT product line is based on the Bluetooth SIG qualified mesh and represents a wireless ecosystem for field devices. Other product lines (e.g. L-DALI sensors) with Bluetooth use BLE to advertise either standard beacons with configurable identifier like iBeacon or EddyStone-UID which allows them to be perfectly integrated in indoor navigation systems. The L-WEB beacon enables secure room operation using the L-WEB-App, as it restricts access to LWEB-900 functions to the close vicinity of the L-WEB beacon.
