Hello,
I'm facing a strange issue with esp8285-01.

As my sketch works good with esp8266-01 while running under 8285-01, I've garbage chars into serial.
Ex : returning seconds since boot :

At least put up some code and (if possible) schematics. Now we've got nothing to go on...

Thank you for this fast reply.

My code is pretty simple :

Code: Select all

void setup() {

Serial.begin(115200);
}

void loop() {
Serial.println(round(millis()/1000));
delay(1000);
}
