ESP8266-01 showing garbage in serial monitor
Posted: Wed Mar 02, 2016 9:16 pmI have my ESP8266 connected via serial to USB like the image shows:
It worked just fine, however, when I tried flashing Blynk code
It started outputting loads of garbage in the serial monitor, while Blynk app said ESP is not connected to network. I've tried since then flashing empty sketches or some other stuff from examples, whatever I do, serial monitor shows loads of junk. I've tried changing modes, I've tried changing baud rates (57600 was default, and AT worked just fine), but all baud rate changes is the junk I see, doesn't stop doing that. It also outputs like 150 symbols a second and doesn't stop.
Junk example:
Has this happened to anyone? The chip is literally new, I've plugged it, ran a test code, flashed Blynk and that's it.
Thanks and have a great day!

Code: Select all
#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
char auth[] = "YourAuthToken";
void setup()
{
Serial.begin(9600);
Blynk.begin(auth, "ssid", "pass");
}
void loop()
{
Blynk.run();
