tl_ble_sdk is a software development platform for Bluetooth® Low Energy (BLE) multi-connection IoT applications. Based on Telink's TL721x, TL321x, TL322x, TLSR921x, TLSR922x, TLSR952x series of SoCs, it helps developers quickly build high-performance, low-power BLE products.
The SDK provides a complete software framework, including the BLE protocol stack, hardware drivers, system services, and engineering samples, supporting the full development process from product prototyping to mass production.
tl_ble_sdk adopts a multi-role, multi-connection architecture to meet the development needs of diverse Bluetooth LE multi-connection applications; typcial usage scenarios include gaming, wireless human interface devices, smart homes, positioning and tracking, and electronic shelf label.
- tl_ble_sdk by default supports up to 4 Central and 4 Peripheral connections, but does not support free role switching.
