Don't use mem data

Postby Logan » Mon Dec 25, 2017 4:44 am

Hi,
I am using esp-wroom-02 module, and using arduino and a logic serial converter for the signals to rx and tx pin. I am putting the module under UART mode and my codes are:

Code: Select all

#include <SoftwareSerial.h>
SoftwareSerial mySerial(2,3); // RX, TX
void setup()
{
 
  Serial.begin(115200);
 
  mySerial.begin(115200);
  //Serial.print(78);
}
void loop()
{
   //Serial.print(mySerial.available());
   //Serial.print(Serial.available());
  if(mySerial.available()){
  Serial.write(mySerial.read());
  //Serial.print(78);
  }
 
 if (Serial.available()){
    //Serial.print(78);
  mySerial.write(Serial.read());
 
  }
 
}

But I keep getting messages like "don't use RTC mem data" does anyone know what the message means and how to solve it? I have attached the messages.
Thanks a lot!!!

The message just means that the RTC memory data is not to be used. I don't think that would potentially cause any problem in your application.
And what is up with the corrupted symbols? Looks like a lot of baud rate error in the logs!
