使用手机APP通过smart config来配置RTOS版本的ESP8266，双方握手不能成功，为什么？

使用手机APP通过smart config来配置RTOS版本的ESP8266，发现双方握手不能成功，

手机是iphone6 ios8.3。ESP touch v0.3.3。用xCode7做设备调试的时候，可以输出“send gc code”，前端日志如下：

可见，后端的平台任务线程一直等待configing完成，而smart config 任务线程不能接收到手机APP发出的SSID和PASSWD指令，无法进入到SC_STATUS_GETTING_SSID_PSWD状态
同时，开发板上的smart config LED蓝色灯一会慢闪一阵，一会快闪一阵子，不断这样变化，请问问题在什么地方？
