ESP8266 SDK开发: 物联网篇-ESP8266配网 SmartConfig

前言

　　SmartConfig配网是在手机APP连接路由器的情况下.

　　APP发送无线信息在空中.

　　Wi-Fi模块通过监测空中的无线信息实现的获取路由器名称和密码

1.包含以下头文件

#include "smartconfig.h"

2.编写配网程序

void smartconfig_callback(sc_status status, void *pdata){
    switch(status) {
        case SC_STATUS_WAIT:
            os_printf("SC_STATUS_WAIT\n");
            break;
        case SC_STATUS_FIND_CHANNEL:
            os_printf("SC_STATUS_FIND_CHANNEL\n");
            break;
        case SC_STATUS_GETTING_SSID_PSWD:
            os_printf("SC_STATUS_GETTING_SSID_PSWD\n");
            sc_type *type = pdata;
            if (*type == SC_TYPE_ESPTOUCH) {
                os_printf("SC_TYPE:SC_TYPE_ESPTOUCH\n");
            } else {
                os_printf("SC_TYPE:SC_TYPE_AIRKISS\n");
            }
            break;
        case SC_STATUS_LINK://获取到手机发来的无线信息
            os_printf("SC_STATUS_LINK\n");
            struct station_config *sta_conf = pdata;
            //连接路由器
            WIFI_Connect(sta_conf->ssid, sta_conf->password, wifiConnectCb);
            break;
        case SC_STATUS_LINK_OVER:
            os_printf("SC_STATUS_LINK_OVER\n");
            if (pdata != NULL) {
                uint8 phone_ip[4] = {0};
                memcpy(phone_ip, (uint8*)pdata, 4);
                os_printf("Phone ip: %d.%d.%d.%d\n",phone_ip[0],phone_ip[1],phone_ip[2],phone_ip[3]);
            }
            smartconfig_stop();
            break;
    }
}

void wifiConnectCb(uint8_t status)
{
    if(status == STATION_GOT_IP){
        os_printf("\nConnect AP Success\n");
    } else {
        os_printf("\nDisConnect AP\n");
    }
}

3.测试

请使用第一节里面的APP进行测试

https://www.cnblogs.com/yangfengwu/p/11961168.html

如果想自己做SmartConfig的APP,请看这一节文章

https://www.cnblogs.com/yangfengwu/p/11911992.html

3.1,安装手机APP

3.2,点击APP右上角菜单

3.3,连接家里的路由器,输入路由器密码

3.4 下载好Wi-Fi模块程序

3.5,点击APP上面的搜索设备按钮

3.6 使用串口调试助手查看Wi-Fi打印的数据

4.优化:长按按钮3S,指示灯快闪,进入配网模式

int KeyDelay=0;//检测按键延时
int SmartConfigDelay=0;//控制LED闪耀时间
int SmartConfigFlag=0;//开始配网标志

    //定时器初始化
    hw_timer_init(0,1);//1:循环
    //设置定时器回调函数
    hw_timer_set_func(hw_test_timer_cb);//hw_test_timer_cb:硬件定时器中断回调函数
    hw_timer_arm(1000);//1000:1000us定时进入中断函数

//按钮按下
    if(GPIO_INPUT_GET(0) == 0){
        KeyDelay++;
        if(KeyDelay>=3000 && SmartConfigFlag==0){
            KeyDelay = 0;
            SmartConfigFlag = 1;
            wifi_set_opmode_current(STATION_MODE);//STATION模式下才能配网
            smartconfig_set_type(SC_TYPE_ESPTOUCH_AIRKISS);//smartconfig + airkiss(APP+微信)
            esptouch_set_timeout(60);//超时时间60S
            smartconfig_start(smartconfig_callback);//设置配网回调函数
        }
    }
    else{
        KeyDelay=0;
    }
    //控制指示灯快闪
    if(SmartConfigFlag == 1){
        SmartConfigDelay++;
        if(SmartConfigDelay>100){
            SmartConfigDelay=0;
            GPIO_OUTPUT_SET(2, 1-GPIO_INPUT_GET(2));
        }
    }

        SmartConfigDelay=0;
    }
