dear tuanpmt

my problem is esp8266 didn't connect again if i turn off then turn on my router, i

1. how to check my esp wifi connection status, i've been try using waitReturn but return value always false?
2. how can i check payload is published or not?

sorry for my bad english thank you

when you subscribe callback esp.wifiCb.attach(&wifiCb) it will call wifiCb everytime wifi status changed. You need to check status like this

void wifiCb(void* response)
{
  uint32_t status;
  RESPONSE res(response);

  if(res.getArgc() == 1) {
    res.popArgs((uint8_t*)&status, 4);
    if(status == STATION_GOT_IP) {
      debugPort.println("WIFI CONNECTED");
      wifiConnected = true;

    } else {
      wifiConnected = false;
    }

  }
}

i think, i'll set my device to subscribe, just like published status, but i still thinking what is better way for this anyway thank so much mr tuanpmt
