Connecting to blynk-cloud.com:80 --> Login timeout

Solved

Hi all,

I’ve search every post I could find and can’t find the answer to this issue…

I’m using an ESP2866 ESP01s, simply connected and uploaded the ESP8266_Standalone sketch with the WIFI and Auth values entered. This works fine on my D1 Mini without a glitch, but I get this on the ESP01. While it’s connected for a second or less at a time, I’m able to send commands to it, but it never remains connected longer than a second or 2:

The code is out of the box with BLYNK_DEBUG added:

#define BLYNK_PRINT Serial
#define BLYNK_DEBUG  // Optional, this enables more detailed prints
#include <ESP8266WiFi.h>  // for ESP8266
#include <BlynkSimpleEsp8266.h>  // for ESP8266

char auth[] = "**********";
char ssid[] = "**********";
char pass[] = "**********";

void setup()
{
  // Debug console
  Serial.begin(9600);
  Blynk.begin(auth, ssid, pass);
}

void loop()
{
  Blynk.run();
}

Also the Blynk App constantly shows “[app name] Connected”, “[app name] Disconnected”.

Any ideas? Only a problem with my 2 ESP01 chips, but not the D1 Mini on the same network.

How are you getting Serial prints from an ESP-01?

Actually, it is not connecting to the server at all.

3

The output is also out of the box with the Blynk Standalone sketch. None of this is custom code.

It is definitely connecting intermittently for a very short while at a time. I can occasionally control the pins using the Blynk app if I get the timing just right.

4

Not my point… the ESP only has one Serial connection, and it is unusable when WiFi is being used… and visa versa, so perhaps that is your problem right there?

Hah! It was a bit of a cryptic answer but I got it. Thanks Gunner. I commented out the #define BLYNK_PRINT Serial line and it stopped serial printing which in turn stopped interfering with the WIFI.

Solved!

I actually didn’t put it together myself until my last comment :smiley:
