"DSR is off" problem

Hi, I’m JB who started to use blynk for 4month, usually, I worked with cloud server. But, today I made my own server on windows and try to use blynk with arduino uno with usb serial before my nodeMCU comes, I did everything same as what I did with cloud server and did

’ C:\Users\북 4>cd C:\Users\북 4\Documents\Arduino\libraries\Blynk\scripts

C:\Users\북 4\Documents\Arduino\libraries\Blynk\scripts>blynk-ser.bat -c COM4 -b9600 -s 192.168.35.241 -p 9443’

did this on CMD… but It keeps saying that DSR is off… tried some other things on Blynk comunity but didn’t work…

Hope anyone of you can help me :smiley:!

and Here is my code :

#define BLYNK_PRINT DebugSerial


// You could use a spare Hardware Serial on boards that have it (like Mega)
#include <SoftwareSerial.h>
SoftwareSerial DebugSerial(2, 3); // RX, TX

#include <BlynkSimpleStream.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "c33e7c58836e4a9da6965f75759d5b7e";


void setup()
{
  // Debug console
  DebugSerial.begin(9600);

  // Blynk will work through Serial
  // Do not read or write this serial manually in your sketch
  Serial.begin(9600);
  Blynk.begin(Serial, auth);
}

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

I think from memory that’s the response you want and you should be good to go. Remember to keep the command window open though.

That is fine… it is NOT an error.

Unless you are specifically trying to run an SSL library… use port 8080
