SmartConfig example doesn't work with EspTouch Android App

[bzhang222]

Hardware:
Board: ESP32 WROOM
Core Installation/update date: 5/1/2018
IDE name: Arduino IDE
Flash Frequency: 40Mhz
Upload Speed: 115200

Description:
on ESP-32 module, I installed Arduino SmartConfig example, on Android device I installed ESPTouch Android App, I added comment in the smartConfig and I can see password/id is sent to device; and device is able to connect to WIFI AP successfully. But android app ends with "ESPTouch Fail" message

This is a problem because when integrated with other part of android app, android app reports no device gets configured

Sketch:
same as smartconfigure example
#include "WiFi.h"

void setup() {
Serial.begin(115200);

//Init WiFi as Station, start SmartConfig
WiFi.mode(WIFI_AP_STA);
WiFi.beginSmartConfig();

//Wait for SmartConfig packet from mobile
Serial.println("Waiting for SmartConfig.");
while (!WiFi.smartConfigDone()) {
delay(500);
Serial.print(".");
}

Serial.println("");
Serial.println("SmartConfig received.");

//Wait for WiFi to connect to AP
Serial.println("Waiting for WiFi");
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}

Serial.println("WiFi Connected.");

Serial.print("IP Address: ");
Serial.println(WiFi.localIP());
Serial.println(WiFi.SSID());

}

void loop() {
// put your main code here, to run repeatedly:

}
