以最小的努力建立藍牙連接物聯(lián)網(wǎng)無線傳感器原型

　　隨著用戶對物聯(lián)網(wǎng)應用程序的熟悉，開發(fā)人員需要快速響應新出現(xiàn)的機會，使用能夠證明新概念或有競爭力產品的功能完備的原型。然而，大多數(shù)物聯(lián)網(wǎng)開發(fā)解決方案都需要大量努力才能使它們正常工作，特別是在軟件方面。

　　為了加快這一進程，開發(fā)人員需要一種物聯(lián)網(wǎng)開發(fā)解決方案，它能夠消除許多新的物聯(lián)網(wǎng)應用程序的響應速度慢的現(xiàn)有障礙。來自北歐半導體的快速開發(fā)套件滿足了這一需求，為藍牙連接的無線傳感器設計提供了完整的硬件/軟件解決方案。

　　本文將討論設計需求，介紹一種合適的藍牙無線解決方案，并指導開發(fā)人員如何快速地啟動和運行。

　　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.
