Error on page request with captive portal #7
Description
If the ESP is in STA mode, everything works fine. If i use it with it's AP mode and captive request handler it crashes sometimes on page load.
Here is the decoded trace:
CORRUPT HEAP: Bad head at 0x3ffd89f8. Expected 0xabba1234 got 0x00000000

};Here is how it is inited:
void bootHandler::initAP(){
WiFi.softAPConfig(apIP, apIP, netMsk);
WiFi.softAP(firstBootAP_NAME);
dnsServer.start(53, "*", WiFi.softAPIP());
IPAddress myIP = WiFi.softAPIP();
Serial.print("AP IP address: ");
Serial.println(myIP);
}
void bootHandler::initServer(){
captiveSerer.addHandler(new CaptiveRequestHandler()).setFilter(ON_AP_FILTER);
captiveSerer.begin();
}
void bootHandler::setup(){
Serial.println("First boot handling started...");
initAP();
initServer();
}And in the loop there is only the dnsServer request processor for the captive portal
void bootHandler::loop(){
dnsServer.processNextRequest();
}
