   // build esptouch task

   NSString *apSsid = @"wifi-1";

   NSString *apBssid = @"12:34:56:78:9a:bc";

   NSString *apPwd = @"1234567890";

   BOOL isSsidHidden = NO;// whether the Ap's ssid is hidden, it is NO usually

   ESPTouchTask *task = [[ESPTouchTask alloc]initWithApSsid:apSsid

                                             andApBssid:apBssid
   
                                               andApPwd:apPwd
   
                                         andIsSsidHiden:isSsidHidden];
   

   // if you'd like to determine the timeout by yourself, use the follow:

   int timeoutMillisecond = 58000;// it should >= 18000, 58000 is default

   ESPTouchTask *task = [[ESPTouchTask alloc]initWithApSsid:apSsid

                                             andApBssid:apBssid
   
                                               andApPwd:apPwd
   
                                         andIsSsidHiden:isSsidHidden
   
                                  andTimeoutMillisecond:timeoutMillisecond];
   

   // execute for result

   ESPTouchResult *esptouchReult = [task executeForResult];

   // note: one task can't executed more than once:

   ESPTouchTask *esptouchTask = [[ESPTouchTask alloc]initXXX...];

   // wrong usage, which shouldn't happen

   {

   [esptouchTask executeForResult];
   
   [esptouchTask executeForResult];
   

   }

   // correct usage

   {

   [esptouchTask executeForResult];
   
   EsptouchTask *esptouchTask = [[ESPTouchTask alloc]initXXX...];
   
   [esptouchTask executeForResult];
   

   }

==================================v0.2.2==================================

1. add isCancelled API in ESPTouchTask and ESPTouchResult to check whether the task

   is cancelled by user directly.

==================================v0.2.1==================================

1. fix the bug when SSID char is more than one byte value(0xff), esptouch will fail forever

   thx for the engineer in NATop YoungYang's discovery

2. the encoding charset could be set, the default one is "NSUTF8StringEncoding":

   change the macro ESPTOUCH_NSStringEncoding in ESP_ByteUtil.h

   (It will lead to ESPTOUCH fail for wrong CHARSET is set.

   Whether the CHARSET is correct is depend on the phone or pad.

   More info and discussion please refer to http://bbs.espressif.com/viewtopic.php?f=8&t=397)

==================================v0.2.0==================================

1. add check valid mechanism to forbid such situation:

   NSString *apSsid = @"";// or apSsid = null
   
   NSString *apPassword = @"pwd";
   
   EsptouchTask *esptouchTask = [[ESPTouchTask alloc]initWithApSsid:apSsid andApPwd:apPwd]; 
   

2. add check whether the task is executed to forbid such situation,

   thx for the engineer in smartline YuguiYu's proposal:

   NSString *apSsid = @"ssid";
   
   NSString *apPassword = @"pwd";
   
   EsptouchTask *esptouchTask = [[ESPTouchTask alloc]initWithApSsid:apSsid andApPwd:apPwd]; 
   
   // wrong usage, which shouldn't happen
   
   {
   
       [esptouchTask execute];
   
       [esptouchTask execute];
   
   }
   
   // correct usage
   
   {
   
       [esptouchTask execute];
   
       EsptouchTask *esptouchTask = [[ESPTouchTask alloc]initWithApSsid:apSsid andApPwd:apPwd]; 
   
       [esptouchTask execute];
   
   }
   

==================================v0.1.9==================================

1. fix some old bugs in the App

2. Add new Interface of Esptouch task( Smart Configure must v1.1 to support it)

   The usage of it is like this:
   
   // create the Esptouch task
   
   EsptouchTask *esptouchTask = [[ESPTouchTask alloc]initWithApSsid:apSsid andApPwd:apPwd]; 
   
   // execute syn util it suc or timeout
   
   EsptouchResult *result = [esptouchTask executeForResult];
   
   // check whehter the execute is suc
   
   BOOL isSuc = result.isSuc;
   
   // get the device's bssid, the format of the bssid is like this format: @"18fe3497f310"
   
   NSString *bssid = result.bssid;
   
   // when you'd like to interrupt it, just call the method below, and [esptouchTask execute] will return NO after it:
   
   [esptouchTask interrupt];
   

==================================v0.1.7==================================

1. The entrance of the Demo is ESPViewController.m

2. EsptouchTask.h is the interface of Esptouch task.

   The usage of it is like this:
   
   // create the Esptouch task
   
   EsptouchTask *esptouchTask = [[ESPTouchTask alloc]initWithApSsid:apSsid andApPwd:apPwd]; 
   
   // execute syn util it suc or timeout
   
   BOOL result = [esptouchTask execute];
   
   // when you'd like to interrupt it, just call the method below, and [esptouchTask execute] will return NO after it:
   
   [esptouchTask interrupt];
   

3. The abstract interface is in the group esptouch
