I have a larger project that I am trying to integrate with Blynk. I haven’t had any luck, so I decided to scale back and try a simple example.
I am using an Arduino Uno, HC-05 Bluetooth module, a buzzer, and a Samsung tracfone.
I am attempting to use the Blynk Blink example code to make a buzzer buzz…
Here is the code:
#define BLYNK_PRINT Serial
SoftwareSerial SwSerial(10, 11); // RX, TX
char auth = "MyToken";
SoftwareSerial SerialBLE(10, 11); // RX, TX
Serial.println("Waiting for connections...");
I am connecting the Tracfone to a mobile hotspot, then connecting to bluetooth. Both the App and the LED on the HC-05 module confirm my connection.
Pin setup is as follows, for Bluetooth: RX-10, TX-11, GND-GND, +5v-5v. For buzzer: positive-Pin3, negative-GND.
Inside the Blynk app, my buzzer is a slider on Digital Pin 3.
My serial monitor shows: Connecting…Connecting…Connecting…Login Timeout, and repeat.
What am I doing wrong? Is there a problem with using the tracfone? It doesn’t have any minutes, which is why it is being connected to a mobile hotspot.
Please let me know if you need any more information. Thank you.
Edit: It’s been a few days, no response. No ideas? I’m open to anything
Edit2: Can anyone recreate this environment? I have loaded the Tracfone with minutes, so this isn’t the problem.
Edit3: I have ruled out problems with the Arduino Uno or data/power cord. I ran the same steps with a different set.
