Bluetooth®LE
Bluetooth® Low Energy (LE), introduced in Bluetooth® 4.0, forms the backbone of connected IoT ecosystems. Unlike Bluetooth® Classic, Bluetooth® LE prioritizes ultra-low power efficiency and is ideal for applications demanding minimal, infrequent data transfers—such as sensors, wearables, and smart tags. Since 2014, Telink’s proven Bluetooth® LE SoCs and software development kits (SDKs) have driven the global deployment of billions of IoT devices, delivering reliable performance and effortless interoperability.
TLSR8208 Series
The TLSR8208 series is a cost-effective multi-protocol wireless connectivity SoC that supports Bluetooth® Low Energy (LE) standard protocols and proprietary protocols in the 2.4GHz band. The TLSR8208 series offers the common peripheral interfaces and a variety of packaging options, making it an ideal choice for the developing basic IoT devices and wireless transceiver modules.
