Bluetooth Mesh

Bluetooth MeshIn 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. In difference to BLE Bluetooth Mesh is not limited by the direct connection range. In 2023 a reworked version (called “Mesh 1.1”) has been released by the Bluetooth SIG adding Mesh Protocol improvements like Directed Forwarding and Remote Provisioning as well as completely new specifications for Mesh Device Firmware Updates and Mesh Network Lighting Control Profiles.

The LOYBT product line is based on Bluetooth SIG qualified mesh and represents a wireless ecosystem for field devices.
