4.2.5 在iot_app/user/user_main.c中定义airkiss按键监控任务的运行函数airkiss_key_poll_task()

......

#include “driver/delay.h”

#include “espressif/esp_timer.h”

#include “espressif/smartconfig.h”

......

static os_timer_t test_timer;

singed char air_kiss_start_flag=0;

signed int to_stop_app=0;

signed char wifi_reconnect_start_flag=0;

......

void airkiss_key_poll_task(void *pvParameters)

{

unsigned int i,value;

while(1)

{

value=gpio_get_value(AIRKISS_KEY_IO_NUM);

if(!air_kiss_start_flag && !value)

{

delay_s(1);

value=gpio_get_value(AIRKISS_KEY_IO_NUM);

if(!air_kiss_start_flag && !value)

{

os_printf(“begin airkiss!n”);

air_kiss_start_flag=1;

os_timer_disARM(&test_timer);

to_stop_app=1;

//here to stop all app

wifi_reconnect_start_flag=0;

smartconfig_start(smartconfig_done);

os_timer_setfn(&test_timer,(os_timer_func_t *)user_esp_platform_check_ip, NULL);

os_timer_arm(&test_timer,1000,0);

}

delay_ms(500);

}

os_printf(“end airkiss!n”);

vTaskDelete(NULL);

}

用到了延时函数，因此需要将头文件包含进来

用到了定时器，将相应的头文件包含进来

用于进行smartconfig的头文件

用于检测按键的定时器

用于airkiss的标志变量(0:未在airkiss过程中，1:已在airkiss过程中)

用于进入airkiss任务后停止应用的标志变量(0:未停止，1:需要停止)

用于重连wifi的标志

定义airkiss_key_poll_task()函数

获取当前按键的状态

未进入airkiss过程且按键生效

延时1秒后再检查，依然未进入airkiss过程且按键生效

进入airkiss过程中

设置标志

清除定时器

在airkiss过程中需要停止所有应用，其他任务的停止都在这里进行

wifi重连启动标志

启动smartconfig过程，需要定义回调函数smartconfig_done

设置定时器回调函数user_esp_platform_check_ip，该函数用于检查wifi模块是否获得IP地址(smartconfig是否顺利完成)

定时器延时时间为1秒

延时500ms后再检测

任务推出时输出信息

删除任务

4.2.6 在iot_app/user/user_main.c中定义smartconfig_done回调函数

void smartconfig_done(sc_status status, void *pdata)

{

printf(“smartconfig_done---status:%dn”,status);

switch(status)

{

case SC_STATUS_WAIT:

os_printf(“SC_STATUS_WAITn”);

break;

case SC_STATUS_FIND_CHANNEL:

os_printf(“SC_STATUS_FIND_CHANNELn”);

break;

case SC_STATUS_GETTING_SSID_PSWD:

os_printf(“SC_STATUS_GETTING_SSID_PSWDn”);

sc_type *type = pdata;

if(*type == SC_TYPE_ESPTOUCH)

{

os_printf(“SC_TYPE:SC_TYPE_ESPTOUCHn”);

}

else

{

os_printf(“SC_TYPE:SC_TYPE_AIRKISSn”);

}

break;

case SC_STATUS_LINK:

os_printf(“SC_STATUS_LINKn”);

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_OVERn”);

smartconfig_stop();

delay_s(2);

system_restart();

break;

}

定义回调函数smartconfig_done

输出配置状态信息

配置完成

停止配网

延时2秒

系统重启

4.2.7在iot_app/user/user_main.c中定义airkiss_key_poll_task任务中用到的定时器回调函数user_esp_platform_check_ip().

......

#include “espressif/esp_wifi.h”

#include “espressif/esp_sta.h”

#include “espressif/esp_system.h”

......

signed char user_main_start_flag = 0;

......

void user_esp_platform_check_ip(void)

{

unsigned int time = 0;

struct ip_info ipconfig;

os_timer_disarm(&test_timer);

wifi_get_ip_info(STATION_IF, &ipconfig);

if(wifi_station_get_connect_status() == STATION_GOT_IP && ipconfig.ip.addr !=0)

{

os_printf(“got IP!rn”);

if(user_main_start_flag == 0)

{

user_main_start_flag = 1;

// xTaskCreate(et_user_main,”et_user_main”,512,NULL,0,NULL);

}

wifi_reconnect_start_flag = 1;

}

else

{

if( wifi_station_get_connect_status() == STATION_WRONG_PASSWORD ||

wifi_station_get_connect_status() == STATION_NO_AP_FOUND ||

wifi_station_get_connect_status() == STATION_CONNECT_FAIL )

{

if(system_get_time()- time) >= 5000000)

{

os_printf(“connect fail, wrong password or AP not found!n”);

time = system_get_time();

}

if(air_kiss_start_flag == 1)

{

wifi_station_set_reconnect_policy(false);

smartconfig_stop();

air_kiss_start_flag = 0;

}

os_timer_setfn(&test_timer, (os_timer_func_t *)user_esp_platform_check_ip, NULL);

os_timer_arm(&test_timer, 1000, 0);

}

wifi相关的头文件

station相关的头文件

系统时间相关的头文件

主任务是否开启的标志

定时器回调函数

ip配置

停止定时器

获取STATION的IP配置

判断station的IP地址是否获取到且ip配置取到

如果主任务没有开启，则在这里开启主任务

设置主任务已开启标志

开启主任务

wifi重新连接启动标志，IP配置完成后需要重启wifi模块

密码错误

AP没找到

连接失败

每过5秒输出出错信息

取系统时间

设置station断开连接后是否重连：不重连

停止smartconfig

重新设置定时器，检查IP地址的获取与否

4.2.8 设置wifi事件处理回调函数

......

void et_wifi_event_cb(System_Event_t *event)

{

printf("et_wifi_event_cb,event_id:%dn",event->event_id);

switch(event->event_id)

{

case EVENT_STAMODE_SCAN_DONE:

os_printf("scan done n");

break;

case EVENT_STAMODE_CONNECTED:

os_printf("connect to ssid:%s,channel:%d n",event->event_info.connected.ssid,event->event_info.connected.channel);

break;

case EVENT_STAMODE_DISCONNECTED:

os_printf("disconnect from %s, reason:%sn",event->event_info.disconnected.ssid,event->event_info.disconnected.reason);

if(true != wifi_station_get_reconnect_policy())

{

os_printf("et wifi set to reconnectn");

wifi_station_set_reconnect_policy(true);

}

os_printf("wifi reconnect start flag: %dn",wifi_reconnect_start_flag);

if(wifi_reconnect_start_flag == 1)

{

os_printf("wifi connect status:%d, restart system!n",wifi_station_get_connect_status());

system_restart();

}

break;

case EVENT_STAMODE_AUTHMODE_CHANGE:

os_printf("auth mode changed: %d -> %d n",event->event_info.auth_change.old_mode,event->event_info.auth_change.new_mode);

break;

case EVENT_STAMODE_GOT_IP:

os_printf("ip:" IPSTR ",mask:" IPSTR ",gw:" IPSTR,IP2STR(&event->event_info.got_ip.ip),IP2STR(&event->event_info.got_ip.mask),IP2STR(&event->event_info.got_ip.gw));

break;

case EVENT_STAMODE_DHCP_TIMEOUT:

os_printf("wifi dhcp timeoutn");

break;

case EVENT_SOFTAPMODE_STACONNECTED:

os_printf("et station: " MACSTR "join, AID = %dn",MAC2STR(event->event_info.sta_connected.mac),event->event_info.sta_connected.aid);

break;

case EVENT_SOFTAPMODE_STADISCONNECTED://a station disconnected to ESP8266 soft-AP

os_printf("et station: " MACSTR "leave, AID = %dn",MAC2STR(event->event_info.sta_disconnected.mac),event->event_info.sta_disconnected.aid);

break;

default:

break;

}

......

void user_init(void)

{

......

wifi_set_opmode(STATION_MODE);

wifi_reconnect_start_flag = 0;

wifi_set_event_handler_cb(et_wifi_event_cb);

......

}

4.2.9 修改iot_app/Makefile文件

......

SUBDIRS=

4.2.10编译链接

在iot_app目录中运行gen_misc.sh，选择正确的配置参数。将生成的bin文件烧录到开发板后，进行调试和测试。局域网配网使用的app为espressif提供的apk demo，版本号V0.3.3或V0.3.4.3，apk demo可以在espressif官方网站上下载。

以上为freeRTOS输出的信息

SDK版本号

以上espressif SDK V1.4输出的信息

应用输出信息

sdk输出信息

应用输出信息

长按boot键进行配网

进入状态1----等待配网状态(wifi模块进入杂凑模式，收听广播消息)

这时在手机上启动espressif apk demo，输入路由器密码并confirm。手机广播SSID和PSWD。

配网类型：ESPTOUCH

AP通道号为11

AP MAC地址

进入状态2-----获取SSID/PSWD

已经收到广播信息，下面对SSID和PSWD进行解析

解析出PSWD和SSID

进入状态3-LINK

连接到AP

WIFI事件，状态1----EVENT_STAMODE_CONNECTED

<-这是SDK的输出

WIFI事件，状态4----EVENT_STAMODE_GOT_IP

获取到IP

到这里后配网成功，SMARTCONFIG等待客户端的confirm。客户端confirm后，才进入SC_STATUS_LINK_OVER状态，在该状态将重启系统。

WIFI事件，进入状态2----EVENT_STAMODE_DISCONNECTED

重新启动成功

连接到AP并成功分配IP地址

至此，smartconfig功能已经完成。

楼主你这一统统的代码是要上天嘛？也不说明一下是要干嘛！

CHNlyt · 2016-9-25 12:37:57

哎，后悔了。当年读书怎么就没多看这些牛人了

2017-12-20 22:26:47

你好，请问一下wifi_set_event_handler_cb(et_wifi_event_cb);这个函数是怎么把et_wifi_event_cb(System_Event_t *event)中的event参数传递进来的？
