ESP8266 smartconfig学习

上一次在程序中指定了路由器的SSID和密码，然后连接WiFi。

使用ESP8266的smartconfig接口，可以从手机的APP端给ESP8266传路由器的SSID和密码。

在系统初始化之后回调smartconfig接口即可：

void ICACHE_FLASH_ATTR    smartconfig_done(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:

                os_printf("SC_STATUS_LINK\n");

                struct station_config *sta_conf = pdata;

                wifi_station_set_config(sta_conf);

                wifi_station_disconnect();

                wifi_station_connect();

                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 ICACHE_FLASH_ATTR to_scan(void){

    wifi_station_disconnect();

    smartconfig_start(smartconfig_done);

}

void ICACHE_FLASH_ATTR  user_init(){

    uart_init(BIT_RATE_115200, BIT_RATE_115200);

    wifi_set_opmode(0x01);

    system_init_done_cb(to_scan);

}

调用结果如图：
