关于原子STM32mini板上传数据至服务器(OneNET)

2017-8-15 22:51:46 4867 STM32 ESP8266 OneNET

   终于结束了四天三夜的电赛，之后睡到绝望。好的废话不多说。本次的帖子是关于STM32使用esp-8266上传数据至服务器。前期直接使用STM32mini板直接驱动esp-8266时，无法正常使用该模块，排除了程序上的问题后，开始找找硬件电路上存在的问题。后来找到了OneNET麒麟座开发板的原理图，根据其esp-8266的应用电路搭了个类似于转接板的东西。

                  图1.应用电路

               图2.转接小板
   使用了这应用电路之后esp-8266总算能够正常的工作了，参考了例程进行了配置，但是还是无法连接服务器。esp-8266同样是使用AT指令进行操作的，所以还是按照了以前写过的一个SIM808C通信的进行使用，移植后能正常通信，上传数据。
