Connnection with high ping after connection failed

svalbard · October 16, 2022, 3:40pm

Hello Dear community
Arduino Atmega2560
ethernet lan (ENC28J60) for ethernet connection
2 x dht 11 sensor
1x anenometre for windspeed

ı have a project also ı have no problem in my home but
when ı go to my office ı cant connect to blynk.cloud ı have two problems outside
issue is —> seeing like this {{ [504712] Connecting to blynk-cloud.com: 0 }}
İf the port 80 like this [504712] Connecting to blynk-cloud.com: 80 ı can connect but with high ping between (250-600 ms ) after try to reconnect but when try to reconnect port ‘’ 0 ‘’ not : 80 port thus ı cant connect blynk server.
in my home everything be okay but office not be okay

in my opinion about ----- > bad internet connection but how can ı sure there is ethernet good or bad
also my serial monitor:

Wow!
I think this is going to be the winner of the “Worst void loop() of the year awards - 2022”

I’d bet that the reason your sketch is disconnecting in the first place is that void loop.
You should read this…

You already have a BlynkTimer set up, but you’re also doing millis() comparisons in your sketch too. Get rid of the millis stuff and user timers instead.

Also, you shouldn’t this:

instead, if you really feel the need to explicitly specify the server address you should use:

Blynk.begin(auth, "fra1.blynk.cloud", 80);

because the server IPs may change, but the regional subdomains won’t.

There are lots of other bits of your code that are a total mess. Just a couple of examples…

Blynk.virtualWrite’s in void setup very rarely work. If you wnat them to run once whne the device connects to the server you should put them in BLYNK_CONNECTED()

svalbard:

  float h = dht.readHumidity();
  float t = dht.readTemperature();
  float h1 = dht0.readHumidity();
  float t1 = dht0.readTemperature();
  Blynk.run();
  timer.run();

  
  if (Blynk.connected()) {
    Serial.println("blnyk conneck oldi ");
    Blynk.run();
    timer.run();
    float h = dht.readHumidity();
    float t = dht.readTemperature();
    float h1 = dht0.readHumidity();
    float t1 = dht0.readTemperature();
  }

The first block of code declares four local variables and takes readings from your DHT11 sensors then executes Blynk.run() (which only achieves anything if Blynk.connected()==true).

The second block, which executes if Blynk.connected()==true, re-declares the same four local variables, takes more readings from your DHT11 sensors (overwriting the previous readings taken a fraction of a second ago) and once again executes Blynk.run().

Because DHT11 sensors don’t like to be read more than about once every 2 seconds (although I’d use 5 seconds to be on the safe side) none of these readings are likely to be useful.
In addition, your veriGonder function also re-declares these same variables as local to that function, and takes more DHT11 readings. This function is called once every half a second with a timer, compounding the problem with your void loop.

You need to take a serious look at your code structure and your variable scope before even starting to think about your ping and port 0- issue, as these may well be caused by the rest of your code.

Maybe you should start with the DHT example from the sketch builder and build-up your sketch in a logical way from there?

Pete.
