This article mainly explains "what are the characteristics of AliOS Things". The explanation in this article is simple and clear, easy to learn and understand. Please follow the ideas of Xiaobian and go deep into it slowly to study and learn "what are the characteristics of AliOS Things" together!

Architecture:

Features:

Basic capability: Low kernel resource consumption (RAM

< 1KB, ROM < 2KB），提供系统和芯片级别安全保护、硬实时能力、低功耗框架、差分OTA等功能。 核心协议栈技术：产品级 TCP/UDP/IPv6/IPv4 支持；MQTT，CoAP，HTTP 支持；WiFi, 蓝牙，LoRA，NB-IoT等协议支持。 自组织网络：支持阿里巴巴自研的uMesh 即插即用网络技术，支持物联网设备上电自动建立通信网络。 设备安全：提供TEE可信计算框架、KM密钥管理、Crypto密码、ID2身份认证、SST安全存储等安全环境，提供需要高安全的应用场景。 可移植性：支持主流的芯片，包括STM32、平头哥、小博通、Nordic蓝牙芯片、NXP、乐鑫、ASR、瑞昱等100多类不同芯片。 调试手段：支持栈回溯以及coredump技术，具备cli终端命令调试；支持日志上传到云端然后智能解析日志定位bug。 HAL 抽象 硬件抽象HAL层最主要的目的是为了屏蔽不同芯片平台的差异，对上提供统一硬件访问接口，从而使上面的软件不会随芯片而改变。目前AliOS Things定义了全面的HAL抽象层，只要对接相应的HAL接口就能控制芯片的控制器，从而达到控制硬件外设的目的。 AliOS Things定义的HAL层硬件包括如下模块： 1 GPIO 2 UART 3 SPI 4 I2C 5 FLASH 6 PWM 7 TIMER 8 WDG 9 RTC 10 ADC 11 DAC 12 RNG 13 I2S 14 QSPI 15 CAN 16 NAND 17 NOR 目前HAL抽象层的定义已经能兼容各主流芯片公司的标准，比如STM32，Beken，全志，NXP等芯片厂商，用户可参照已有平台的HAL封装实现。 网络支持 AliOS Things提供了具备如下功能的Wifi Service模块，方便快速连入Wi-Fi网络。

AliOS Things supports the LwIP 2.0.0 protocol stack, and optimizes the throughput rate. Its performance is better than Linux.

Cloud Platform Adaptation

AliOS Things3.1 on Haas 100 provides LinkKit 3.0.1 cloud components. The following application layer protocols are available:

MQTT;

HTTP;

HTTP2;

CoAP, etc.

At the same time, it provides customized access solutions for Alibaba Cloud IoT platform. Includes:

authentication authentication;

Dynamic connection (one type and one dense);

Secure Channel (MbedTLS/iTLS);

physical model;

child device proxy;

Equipment shadow;

Wi-Fi distribution network and account binding (only for Feiyan platform), etc.

Thank you for reading, the above is the content of "What are the characteristics of AliOS Things?" After studying this article, I believe everyone has a deeper understanding of what the characteristics of AliOS Things are. The specific use situation still needs to be verified by practice. Here is, Xiaobian will push more articles related to knowledge points for everyone, welcome to pay attention!
