Mbed OS是为基于ARM Cortex-M内核的IOT设备提供的开源操作系统，Mbed OS提供了运行在MCU上面的抽象层，所以开发者只需要针对Mbed开发板，编写C/C++应用程序即可。Mbed OS提供了一组优质的API用于开发应用程序，包括了免费的工具，针对通用组件的几千个代码示例、库和驱动。已经内置了安全协议栈、内核组件，如存储和外设的支持等。
已支持的3类编译器和IDE适用于各类需求情况：Mbed在线编译器、Mbed Studio本地IDE和Mbed CLI命令行。
Mbed OS 6.3的更新主要包括：云连接、WiSUN和BLE。
云链接可以使得设备方便的支持微软Azure IoT和Google Cloud IoT。
Wi-SUN是一种组网协议，被用于智慧城市和智能设施的建设。

Mbed OS 6.3 released today[size=0.9em]Last updated about 14 hours ago, by
Andy Powers.The Mbed team are pleased to announce the release of Mbed OS 6.3 today. This release includes features and examples covering;
- Cloud connectivity
- WiSUN
- BLE
Over the past few months, we have begun to release our work to extend cloud service support in Mbed OS, initially by adding an integration with the Amazon Web Services SDK, which we released as part of Mbed 6.0 back in June. We firmly believe that providing examples of how to use Mbed OS with different cloud service providers gives developers using Mbed more choices when it comes to developing their IoT products and so today we’re pleased to release two further cloud service integrations;
- Microsoft Azure IoT
- Google Cloud IoT
You can find out more about these integrations, and see an example of how to use them here
Wi-SUN is a meshing network technology being adopted in smart city and smart metering use cases. Mbed OS first introduced Wi-SUN support in our 5.12 release and we’ve subsequently been adding new features as the technology is becoming more widely adopted. In Mbed OS 6.3 we’ve added new functionality to support setting up and securing a Wi-SUN Border Router.
As we’ve mentioned before, we are also in the process of tidying up the Mbed directory structure as part of the development of the new build tools we’re working on, so further changes to that structure are included in this release.
This release also includes the BLE Integration Test Suite that my colleague Vincent blogged about yesterday.
Mbed OS 6.3 is available now using Mbed Studio and the Mbed Online Compiler, or directly on the Mbed GitHub repository.
