Need help with outputting data to Blynk

through the application, there is no connection, and the port’s monitor writes like this

[0] 
    ___  __          __
   / _ )/ /_ _____  / /__
  / _  / / // / _ \/  '_/
 /____/_/\_, /_//_/_/\_\
        /___/ v0.6.7 on Arduino Uno

I’m trying to connect via a smartphone, the indicator on the HC06 is lit that is connected, not in the app, there is no indication on the port monitor

Does the BLE widget in the app show your device and allow you to create a connection?

I’ve just noticed that you are using BTSerial for your debug messages…

zeromax911:

void myTimerEvent() {
    emon1.calcVI(20, 2000);
    BTSerial.print("\tIrms: ");      <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
    BTSerial.print(emon1.Irms, 4);   <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
    BTSerial.print("A");             <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
    Blynk.virtualWrite(V1, emon1.Irms);
    Serial.print("\tPower: ");
    Serial.print(emon1.Irms*220, 4);
    Serial.print("W");
    Blynk.virtualWrite(V2, emon1.apparentPower);
    Serial.print("\tkWh: ");
    kWh = kWh + emon1.Irms*220*(millis()-lastmillis)/3600000000.0;
    Serial.print(kWh, 4);
    Serial.println("kWh");
    lastmillis = millis();
    Blynk.virtualWrite(V3, kWh);
}

As I said before, you can’t do this.

BTSerial is for the connection to the BT module ONLY

Serial is for debug messages using Serial.print

yes, I connected without any problems

yes, initially just Serial. print. what I wrote BT Serial thought this is the problem, but when Serial. print also does not work
