出現該錯誤的原因是在模組獲取都WIFI的名字和密碼後會關閉WIFI的混雜模式，此時如果模組的通道與要連線的WIFI通道不一樣就會呼叫aws_try_adjust_chan函式切換通道，就會產生該錯誤。這是由於zconfig_got_ssid_passwd_callback函式和aws_main_thread_func函式中的aws_try_adjust_chan函式呼叫時機引起的。

解決方法： 在zconfig_got_ssid_passwd_callback函式中，將WIFI模組的通道設定成被連線的WIFI的通道

void zconfig_got_ssid_passwd_callback(u8 *ssid, u8 *passwd,
                                      u8 *bssid, u8 auth, u8 encry, u8 channel)
{
    ........
    aws_result_auth = auth;
    aws_result_encry = encry;
    aws_result_channel = channel;

	//切換通道
	if(aws_locked_chn !=aws_result_channel)
	{
		aws_set_dst_chan(aws_result_channel);
		aws_switch_channel();
	}
   ........
}
