机智云Gokit2开发板,ESP8266刷AT固件后,使用基于ebox代码在线稳定性测试。有教程有源码。。。

一、设备功能

机智云gokit开发板实时上传DHT11温湿度数据,接受控制并进行反馈,保持断线重连,可以通过开发板的usb口,用串口工具调试工具,直接控制esp8266。

机智云gokit开发板连接贝壳物联

二、硬件

gokit开发板2.0v,esp8266网络模块。

三、实现方法

1、gokit扩展板上的esp8266刷AT固件,参见:机智云Gokit2代功能板ESP-12F直接刷AT固件透传方法

2、下载基于ebox系统的stm32,工程文件,点击下载

3、复制下方代码,粘贴替换下载工程文件中的mian.cpp文件内容;

4、修改文件中的DEVICEID、APIKEY、temp_input_id、hum_input_id,分别为设备id,设备密码,属于该设备下的温度接口和湿度接口id;

5、编译烧录;

6、进行透传设置,直接通过gokit的usb口,使用串口调试工具,向esp8266发送命令进行透传设置,可参见:ESP8266透传设置脚本,设置成功后自动连接贝壳物联平台 ,请透传8282端口。

四、代码
