Blynk.begin(SerialBLE, auth) -> skip initial BT connection attempt

Solved

Hi Blynk Community,

i just did my first Projekt using Blynk and itś working great sending data from an arduino via ht05 Bluetooth module to the app.

My Issue:
Using the “Push Data” example i would like to start my code without establishing a Bluetooth connection on first boot.

I tried adding Blynk.disconnect() with no luck, but also not sure if this is suitable for BT connections…


#define BLYNK_PRINT Serial


#include <SoftwareSerial.h>
SoftwareSerial SwSerial(10, 11); // RX, TX
    
#include <BlynkSimpleSerialBLE.h>
#include <SoftwareSerial.h>

char auth[] = "YourAuthToken";

SoftwareSerial SerialBLE(10, 11); // RX, TX

BlynkTimer timer;

void myTimerEvent()
{
  // You can send any value at any time.
  // Please don't send more that 10 values per second.
  Blynk.virtualWrite(V5, millis() / 1000);
}

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

  SerialBLE.begin(9600);
  Blynk.begin(SerialBLE, auth);
//>>>>>>>     Stuck here forever without BT connection <<<<<<<<<<
//Blynk.disconnect()  >>>>> not working
  Serial.println("Waiting for connections...");

  timer.setInterval(1000L, myTimerEvent);
}

void loop()
{
  Blynk.run();
  timer.run(); // Initiates BlynkTimer
}

Thanks a lot for your help!

try using lynk.config: http://docs.blynk.cc/#blynk-firmware-configuration-blynkconfig
and then blynk.connect http://docs.blynk.cc/#blynk-firmware-connection-management-blynkconnect

Hi wolph42,

Using Blynk.config() instead of Blynk.begin() worked perfect for me.

Blynk.connect() is not needed at all to get everything running. (at least for BT connection…)

Appreciate your help, thank you :slight_smile:
