Introduction

The BM70/71 module offers BLE solutions for embedded applications. It conforms to the Bluetooth 5 core specification to enhance the throughput and security for the IoT applications. It also supports beacon technology to enhance the user experience for the IoT applications, and enables users to control the cloud and receive data without opening the application through a smartphone. The BM70/71 module has an integrated Bluetooth stack and is available in different form factors to optimize space, cost, and RF performance. The power-optimized design minimizes the current consumption and extends battery life for portable and wearable applications.
