I use 4G transparent transmission mode to connect to arduino mega. Blynk app shows that it is connected, but the arduino ide debug port shows connecting login timeout.
This is my code, it’s a simple example sketch.

#define BLYNK_PRINT Serial
#include <SoftwareSerial.h>
#include <BlynkSimpleStream.h>

SoftwareSerial DebugSerial(A4, A5); //RX TX

char auth[] = "eacsmx5z2RvmYI4bKSLFkN6JgtjotL4k";

void setup() {
  Serial.begin(115200);
  DebugSerial.begin(9600);
  Blynk.begin(DebugSerial, auth);
}

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

When you post serial output, please post it as text, with triple backticks, rather than a screenshot.

This should say v1.3.2

I guess you probably have Blynk for Chinese installed, or a VERY old version of the Blynk library.

Thank you very much, PeteKnight. I will try it on.

It dose not work.

I suggest you provide more information about the Blynk libraries you have installed, or if you’re getting a different serial output message then the details of that message.

Also, details of your hardware would help.

Pete.
