- In addition, don't take my blog as a learning standard, mine are just notes, and it's hard to be negligent. If there are any, please point them out, and welcome to leave a message!
The WeChat IoT ecology is mainly divided into the WeChat hardware development platform and the Tencent IoT development platform . The former has stopped maintenance, but still has great learning value, while the latter, as the main platform, integrates many functions, including realizing distribution from WeChat applets. network to control;
In order to take care of more friends and my own study notes, I will keep updating this special note. Welcome to pay attention to my CSDN half heart , and take you into the frontier field and learn the frontier technology!

I. Introduction
My previous article mentioned how and what is the LLSyncprotocol of the Tencent IoT Development Platform, now let's practice it.
This project blog post is used as a sample project of Anxinke Technology NodeMCU-ESP32Development Board & Tencent IoT Development Platform Distribution Network + Communication. Based on Anxinke Technology NodeMCU-ESP32Development Board, it demonstrates that terminal devices pass through LLSync SDKand Explorer SDKperform network distribution and communicate with the cloud.
