上一次在程序中指定了路由器的SSID和密碼，然后連接WiFi。

使用ESP8266的smartconfig接口，可以從手機(jī)的APP端給ESP8266傳路由器的SSID和密碼。

在系統(tǒng)初始化之后回調(diào)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);

}

調(diào)用結(jié)果如圖：
