Telink’s Bluetooth mesh extended to add Bluetooth SIG standard
This adds to its own Bluetooth mesh networking protocol; Telink Semiconductor previously offered features such as real-time updates and synchronized control for applications such as lighting, healthcare and industrial control.
Mesh networking opens up the use of Bluetooth for ‘many-to-many’ or multicast traffic device communications, making it suitable for implementing mesh networks in beacons, robotics, industrial automation, energy management, smart city applications, and other industrial IoT (internet of things) and advanced manufacturing solutions.
Bluetooth mesh networking utilizes a ‘managed flood’ approach for message transmission, which is a simple and reliable form of message relay that is uniquely suited for low-power wireless mesh networks, especially those handling a significant amount of multicast traffic. This makes flood-based message relay an ideal approach for the strict reliability, scalability, and performance requirements of commercial and industrial markets.
According to ABI Research, 48 billion internet-enabled devices are expected to be installed by 2021, of which nearly one-third will include Bluetooth; the Bluetooth SIG expects that Bluetooth mesh will make the largest initial impact in commercial lighting and industrial applications.
Telink Semiconductor has been offering its own proprietary Bluetooth Low Energy (LE) mesh networking protocol for several years – for example, last year the company announced that its BLE SoC chip and mesh technology are being used in connected LED light bulbs from GE Lighting, in its C by GE product family.
The software development kit (SDK) is fully compatible with the Bluetooth SIG mesh specification. In addition to meeting the standard specification, Telink’s devices have features such as being able to update in real-time with complete and efficient presence information sharing on the network to reflect multiple nodes’ status automatically. Telink mesh supports a synchronized control mechanism within multiple or large mesh networks, which in a smart lighting application for example can guarantee a large number of lights to be on/off or controlled at exactly same time.
Telink’s BLE mesh technology can support multiple terminals to control multiple smart devices simultaneously in real time. Using Telink’s patented network traffic control technology, it enables the system to update and reflect the status of multiple smart devices on every control terminal in time and automatically; without this, it could result in inconsistent control and might lead to devices and controllers not being in in sync.
