trying to read\write to serial device - getting garbage

Projects General Guidance

Hello ,
I can't manage to see the serial output of my device(my device using baud-rate of 115200
I have connected it using a RS232-TTL
this is the code I have put - a simple write\read serial
if I write commands to the device I can see it work.

#include <SoftwareSerial.h>
SoftwareSerial mySerial(6,7);// Green-Tx-6,Yellow-Rx-7)
void setup()
{
  Serial.begin(115200); 
  mySerial.begin(115200); 
}

void loop()
{
     if (mySerial.available())
    Serial.write(mySerial.read());
  if (Serial.available())
  
    mySerial.write(Serial.read());  
    
}

this is the output:

the GND is the same for the Arduino+RS232TTL+Device

what else I can check?

Thanks ,

Hi, try a slower speed for a start, like 9600.

Tom..... :slight_smile:

I have thought about it but my device only work at 115200

never mind
found how to change 9needed to enter the device with Admin)

Thanks ,
now working!

Thanks ,
