以最小的努力建立蓝牙连接物联网无线传感器原型
随着用户对物联网应用程序的熟悉，开发人员需要快速响应新出现的机会，使用能够证明新概念或有竞争力产品的功能完备的原型。然而，大多数物联网开发解决方案都需要大量努力才能使它们正常工作，特别是在软件方面。
为了加快这一进程，开发人员需要一种物联网开发解决方案，它能够消除许多新的物联网应用程序的响应速度慢的现有障碍。来自北欧半导体的快速开发套件满足了这一需求，为蓝牙连接的无线传感器设计提供了完整的硬件/软件解决方案。
本文将讨论设计需求，介绍一种合适的蓝牙无线解决方案，并指导开发人员如何快速地启动和运行。
Wireless IoT device requirements and solution options
As the data source for high-level IoT applications， wireless sensor systems need to satisfy a wide range of complex requirements. Among those requirements， expectations for Bluetooth connectivity continues to rise， along with user expectations for easy IoT monitoring and control through smartphone apps. Semiconductor manufacturers have responded to this growing demand with an array of solutions including Bluetooth transceiver ICs， modules， and system-on-chip （SoC） devices.
While each solution addresses different classes of application requirements， Bluetooth SoCs have emerged as a particularly attractive solution for wearables and tiny IoT devices. By integrating a Bluetooth communications subsystem， these devices offer a combination of reduced BOM， small footprint， and minimal power without compromising functionality and performance.
Among devices in this class， the Nordic Semiconductor nRF52832 Bluetooth SoC integrates a processor core and radio subsystem with a flexible software architecture designed to simplify development of wireless systems.
