Async Webserver becomes unresponsive about fsbrowserng HOT 4 OPEN

Well that almost worked. I had about 15 hours of operation without a problem. That's a record.

I should note that the symptoms changed a bit. When the Webserver became unresponsive, Ping continued to work . After an hour or so it recovered on its own for no clear reason.

So: I depreciated the PING solution and added in this proposed solution.

Presently testing. We will see. It is doing something the Webserver is not very snappy as before.

EDIT ** overnight it became unresponsive again:(

This is clearly a work-around, but it seems to resolve 'unresponsive' behavior. Then code it not meant to run alone. Merge it into your existing sketch that has 'unresponsive' issues.

#include <ESP8266HTTPClient.h>
#include <ESP8266WiFi.h>
#include <ESP8266Ping.h>
#define FPM_SLEEP_MAX_TIME 0xFFFFFFF

unsigned long pingTest = 1000UL * 60UL * 30UL; // Test connection every 30 minuites
unsigned long prevMillis = 0; // used for temp timing counter

extern "C" {
#include "user_interface.h" // Required for wifi_station_connect() to work
}

extern "C" {
extern char *netif_list;
uint8_t etharp_request(char *, char *); // required for forceArp to work
}

void forceARP() {
char *netif = netif_list;

while (netif)
{
etharp_request((netif), (netif + 4));
netif = *((char **) netif);
}
}

void setup() {
wifi_set_sleep_type(NONE_SLEEP_T); // May help stability
// add your code to connect to the internet and so forth

}

void loop() {
// ----------------------Connectivity testing within Loop() -----------
HTTPClient http_1; // used in ping test
unsigned long currentMillis = millis(); // timer for data
unsigned long pingMillis = millis(); // timer for data

if ((pingMillis - prevMillis) > pingTest) {
prevMillis = pingMillis;
WiFiOff();
Serial.print("WiFi - OFF ");
delay (20);
WiFiOn();
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("WiFi - ON");
if (Ping.ping(WiFi.gatewayIP())) {
Serial.print("ping gateway Success!! Ping Time (mS) = "); Serial.println(Ping.averageTime());
forceARP();
} else {
Serial.println("Failed ping to gateway!");
ESP.restart();
}
if (Ping.ping(WiFi.localIP()), 1) {
Serial.print("ping localIP Success!! Ping Time (mS) = "); Serial.println(Ping.averageTime());
forceARP();
} else {
Serial.println("ping Error :(");
ESP.restart();

}
http_1.begin("http://api.wunderground.com"); // or some other web site you like
int httpCode = http_1.GET();
if (httpCode > 0) {
Serial.println ("connection test okay!");
}
else {
Serial.print("connection test failed! code: ");
Serial.println(httpCode);
ESP.restart();
}
http_1.end();
}
// -------------------- end testing ---------------------------
// rest of your loop goes here
}

void WiFiOn() {

wifi_fpm_close();

//Serial.println("Reconnecting");
wifi_set_opmode(STATION_MODE);
wifi_station_connect();
}

void WiFiOff() {

//Serial.println("diconnecting client and wifi");
//client.disconnect();
wifi_station_disconnect();
wifi_set_opmode(NULL_MODE);
wifi_set_sleep_type(MODEM_SLEEP_T);
wifi_fpm_open();
wifi_fpm_do_sleep(FPM_SLEEP_MAX_TIME);

Sorry short in time at the moment
May be able to support you in this over the holidays

My temp sensor based on this seems to reboot every few days
And stops responding to are requests
But web server still works. May be related

from fsbrowserng.

Thanks. Possibly related. Also try, accessing the. server from an iPhone using Safari. After a couple of refreshes it begins to ignore the Safari browser. Here'a a link to my sketch. It plots actual temperature vs Wunderground forecast..
