  如何部署一个完整的基于蓝牙的物联网设计为40美元以下

  对于物联网(物联网)设备的开发,蓝牙是一个快速和安全的路由连接和无线片上系统(SoC)设备已成为现成的解决方案,实现蓝牙功能设计。不过,市场压力的时间正在增加,所以即使这些高度集成的解决方案功亏一篑,需要时间和资源来添加硬件和软件需要一个完整的物联网设计。

  本文介绍了一种蓝牙功能的传感器板,它提供了一个即时的物联网解决方案的圣杯,也可以是定制的无线传感器物联网设备为家庭或个人使用的基础设计。然后,它描述了一个现实世界的感知实现的例子,与代码,使用板的应用程序和车载MEMS麦克风。

  Module simplify Bluetooth

  Bluetooth low energy (BLE) offers multiple advantages including low power consumption, high security, and near-universal availability in mobile platforms, including smartphones, tablets, and notebooks. While wide availability of low-cost transceivers fueled rapid acceptance of Bluetooth connectivity, these transceivers still required significant expertise in RF design to build optimized designs.

  Bluetooth modules simplified design, delivering a complete RF subsystem that required engineers to simply integrate an MCU and associated sub-circuits to build a Bluetooth-enabled system. Wireless SoCs such as the Silicon Labs Gecko MCU family are a recent step in this evolution, simplifying implementation while reducing design size and cost.

  For example, the SiLabs EFR32MG1P Mighty Gecko MCU integrates a 32-bit ARM® Cortex®-M4 core, memory, crypto hardware accelerator, DC/DC converters, multiple peripherals, and a transceiver for both 2.4 GHz and sub-GHz communications (Figure 1).
